Abstract
In this study, we investigated the photoreaction of Br U in a pyrene-labeled DNA duplex, RNA duplex, and DNA/RNA hybrids. We found that the photoreactivity of Br U changed dramatically from hydrogen abstraction to cross-linking by changing the conformation of the duplex from the B-form to the A-form. Among three A-form structures, the largest amount of cross-linked products was observed when Br U was incorporated into the RNA strand and the pyrene was conjugated to the 5' end of the DNA. These results indicate that the contact manner of pyrene was different between A- and B-form duplexes. This is a rare example of the use of the reactivity of bromouracil to analyze the contact between a small molecule with a weak binding affinity and a nucleic acid.

Abstract
Perylenediimides (PDIs) are important molecular building blocks that are being investigated for their applicability in optoelectronic technologies. Covalently linking multiple PDI acceptors at the 2,5,8,11 (headland) positions adjacent to the PDI carbonyl groups is reported to yield higher power conversion efficiencies in photovoltaic cells relative to PDI acceptors linked at the 1,6,7,12 (bay) positions. While the photophysical properties of PDIs linked via the bay positions have been investigated extensively, those linked at the headland positions have received far less attention. We showed previously that symmetry-breaking charge separation (SB-CS) in PDIs hold promise as a strategy for increasing photovoltaic efficiency. Here we use transient absorption and emission spectroscopies to investigate the competition between SB-CS, fluorescence, and internal conversion in three related PDI dimers linked at the headland positions with o-, m-, and p-phenylene moieties: o-PDI2, m-PDI2, and p-PDI2, respectively. It is found that o-PDI2 supports SB-CS yielding PDI•+-PDI•-, which is in equilibrium with the o-PDI2 first excited state in a polar solvent (CH2Cl2) while m-PDI2 and p-PDI2 exhibit accelerated internal conversion due to the motion of the linker along with subnanosecond intersystem crossing (ISC). Electronic coupling and structural dynamics are shown to play a significant role, with o-PDI2 being the only member of the series that exhibits significant through-bond interchromophore coupling. The pronounced o-PDI2 steric congestion prevents the free internal rotation that leads to rapid deactivation of the excited state in the other dimers.

Abstract
In the past few decades, charge transfer in DNA has attracted considerable attention from researchers in a wide variety of fields, including bioscience, physical chemistry, and nanotechnology. Charge transfer in DNA has been investigated using various techniques. Among them, time-resolved spectroscopic methods have yielded valuable information on charge transfer dynamics in DNA, providing an important basis for numerical practical applications such as development of new therapy applications and nanomaterials. In DNA, holes and excess electrons act as positive and negative charge carriers, respectively. Although hole transfer dynamics have been investigated in detail, the dynamics of excess electron transfer have only become clearer relatively recently. In the present paper, we summarize studies on the dynamics of hole and excess electron transfer conducted by several groups including our own.

Abstract
The biocompatibility as well as the sustainability of a deep eutectic solvent makes it a good substitute for aqueous media in studying biomolecules. Understanding the structure and stability of natural and non-natural G-quadruplexes in aqueous and highly viscous media will be useful in biological and nanodevice applications. We report the synthesis and conformational analysis of a model G-rich oligonucleotide G3T3 and non-natural G-rich sequences Pyr1-Pyr3 in aqueous and highly viscous media. Progressive increases in the loop replacement with a non-natural pyrene linker leads to a systematic increase of the thermal denaturation temperature of the modified G-rich oligonucleotides Pyr1-Pyr3 in 10 mM cacodylate buffer (pH 7.2) containing 100 mM KCl, as monitored using UV-Vis spectroscopy. A circular dichroism signal clearly revealed the formation of a predominantly anti-parallel vs. parallel conformation in the natural G-rich oligonucleotide G3T3 as well as the non-natural G-rich oligonucleotides Pyr1-Pyr3 in 10 mM cacodylate buffer (pH 7.2) containing 100 mM KCl. On the other hand, we observed thermodynamic destabilization of G-rich oligonucleotides in a deep eutectic solvent (DES; 1 : 2 choline chloride-urea) containing 100 mm KCl with an increase in loop replacements. Interestingly, we observed an exclusively parallel G-quadruplex conformation in the case of G3T3 in DES containing 100 mm KCl. While pyrene containing G-rich oligonucleotides Pyr1-Pyr3 exhibited a predominantly parallel vs. anti-parallel G-quadruplex conformation in DES containing 100 mM KCl.

Abstract
Here we report the substitution effects of N-alkyl and N,N-dialkyl carboxamide groups on the fluorescence properties of polycyclic aromatic hydrocarbon chromophores, so as to control their fluorescence properties. The fluorescence properties of compounds obtained using solvents with different polarities showed very little change, indicating that the modified compounds do not form charge transfer states. TD-DFT calculations and measurements performed at low temperature (78 K) and in viscous solvents revealed that the N-alkyl and N,N-dialkyl carboxamide groups tend to reduce the contributions from intersystem crossing and increase those from internal conversion. Considering that the fluorescence mechanism of low-fluorescence carbonyl compounds such as aldehyde and ketone is dominated by intersystem crossing and that of high-luminescence carbonyl compounds such as carboxylic acid and ester is dominated by a radiative process, it can be said that the photophysical process of N-alkyl and N,N-dialkyl carboxamides is novel. In addition, the calculation results for excited states indicated that such contributions can be controlled by selecting the appropriate polycyclic aromatic hydrocarbon or amide structure, in addition to solvent viscosity and temperature.

Abstract
Cyclobutane-pyrimidine dimer yields in UV-irradiated DNA are controlled by the equilibrium between forward and reverse photoreactions. Past studies have shown that dimer yields are suppressed at sites adjacent to a purine base, but the underlying causes are unclear. In order to investigate whether this suppression is the result of repair by electron transfer from a neighboring nucleobase, the yields and dynamics of the reverse reaction were studied using trinucleotides containing a cis-syn dimer (T<>T) flanked on the 5' or the 3' side by adenine or guanine. The probability of forming an excited state on T<>T or on the purine base was varied by tuning the irradiation wavelength between 240 and 280 nm. Cleavage quantum yields decrease by an order of magnitude over this wavelength range and are less than 1% at 280 nm, a wavelength that excites the purine base with more than 95% probability. Conditional quantum yields of cleavage for the trinucleotides given excitation of T<>T are similar in magnitude to the quantum yield of cleavage of unmodified T<>T. These results indicate that within experimental uncertainty all photoreversal in these single-stranded substrates is the result of direct electronic excitation of T<>T. Photolyase-like repair of T<>T due to electron transfer from an adjacent purine is negligible in these substrates. Instead, the observed variation in photoreversal quantum yields for adenine- versus guanine-flanked cis-syn dimer could be due to uncertainties in absorption cross sections or to a modest quenching effect by the purine on the excited state of T<>T. Pump-probe measurements reveal that the excited-state lifetimes of A or G in the dimer-containing trinucleotides are unperturbed by the neighboring dimer, indicating that electron transfer from purine base to T<>T is not competitive with rapid excited-state deactivation. Pump-probe measurements on unmodified T<>T in aqueous solution indicate that cleavage is most likely complete on a picosecond or subpicosecond time scale.

Abstract
Detecting short RNA strands with high fidelity at any of the bases of their sequence, including the termini, can be challenging, since fraying, wobbling, and refolding all compete with canonical base pairing. We performed a search for 5'-substituents of oligodeoxynucleotides that increase base pairing fidelity at the terminus of duplexes with RNA target strands. From a total of over 70 caps, differing in stacking moiety and linker, a phosphodiester-linked sequence of the residues of L-prolinol, glycine, and oxolinic acid, dubbed ogOA, was identified as a 5'-cap that stabilizes any of the four canonical base pairs, with ΔT(m) values of up to +13.1 °C for an octamer. At the same time, the cap increases discrimination against any of the 12 possible terminal mismatches, including mismatches that are more stable than their perfectly matched counterparts in the control duplex, such as A:A. A probe with the cap also showed increased selectivity in the detection of two closely related microRNAs, let7c and let7a, with a ΔT(m) value of 9.2 °C. Melting curves also yielded thermodynamic data that shed light on the uniformity of molecular recognition in the sequence space of DNA:DNA and DNA:RNA duplexes. Hybridization probes with fidelity-enhancing caps should find applications in the individual and parallel detection of biologically active RNA species.

Abstract
To investigate the parameters and rates that determine excess-electron transfer processes in DNA duplexes, we developed a DNA double-duplex system containing a reduced and deprotonated flavin donor at the junction of two duplexes with either the same or different electron acceptors in the individual duplex substructures. This model system allows us to bring the two electron acceptors in the duplex substructures into direct competition for injected electrons and this enables us to decipher how the kind of acceptor influences the transfer data. Measurements with the electron acceptors 8-bromo-dA (BrdA), 8-bromo-dG (BrdG), 5-bromo-dU (BrdU), and a cyclobutane pyrimidine dimer, which is a UV-induced DNA lesion, allowed us to obtain directly the maximum overall reaction rates of these acceptors and especially of the T=T dimer with the injected electrons in the duplex. In line with previous observations, we detected that the overall dimer cleavage rate is about one order of magnitude slower than the debromination of BrdU. Furthermore, we present a more detailed explanation of why sequence dependence cannot be observed when a T=T dimer is used as the acceptor and we estimate the absolute excess-electron hopping rates.
