Abstract
![]()
The synthesis of calix[4]- and -[6]arene derivatives P6(H)22+·(Cl–)2, V4(H)24+·(Cl–)2·(I–)2, and V6(H)24+·(Cl–)2·(I–)2 bearing N-linked pyridinium (P) and viologen (V) units at the upper rim is described here. A rare example
of an anionic conformational template is reported for p-pyridiniumcalix[6]arene P6(H)22+, which adopts a 1,3,5-alternate conformation in the presence of
chloride anions. Derivatives P6(H)22+·(Cl–)2, V6(H)24+·(Cl–)2·(I–)2, and V4(H)24+·(Cl–)2·(I–)2 show a negative solvatochromism, while their UV–vis
acid–base titration evidenced that upon addition of a base,
new bands appear at 487, 583, and 686 nm, respectively, due to the
formation of betainic monodeprotonated species P6(H)1+, V6(H)13+,
and V4(H)13+. These new bands were
attributable to the intramolecular charge-transfer (CT) transition
from the phenoxide to the pyridinium or viologen moiety and were responsive
to the presence of cations. In fact, the band at 487 nm of P6(H)1+ was quenched in the presence of a hard
Li+ cation, and the color of its acetonitrile solution
was changed from pink to colorless upon addition of LiI. Consequently,
this derivative can be considered as a useful host for the recognition
and sensing of lithium cations.

Abstract
We have studied the interaction of a polymeric water soluble anthracenyl derivative () with salmon testes DNA. The results from UV-Vis, fluorescence, Fourier transform infrared (FT-IR) and circular dichroism spectroscopies indicate that the groove binding process regulates the interaction between and DNA. The binding constants, calculated by absorption spectroscopy at 298, 304 and 310 K, were equal to 3.2 × 10(5) M(-1), 4.7 × 10(5) M(-1), and 6.6 × 10(5) M(-1) respectively, proving a relatively high affinity of for salmon testes DNA. Results of Hoechst 33258 displacement assays strongly support the groove binding mode of to DNA. The association stoichiometry of the :DNA adduct was found to be 1 for every 5 base pairs. FT-IR spectra, recorded at different /DNA molar ratios, indicate the involvement of the phosphate groups and adenine and thymine DNA bases in the association process. Thermodynamic results suggest that hydrophobic forces regulate the binding of with DNA without excluding some extent of involvement of van der Waals forces and hydrogen bonding arising due to surface binding between the hydrophilic polymeric arms of the ligand and the functional groups positioned on the edge of the groove. The resulting composite biomaterial could constitute a valuable candidate for future biological and/or photonic applications.

Abstract
Photochromic azobenzene cellulose ethers were prepared by homogeneous etherification of cellulose with 2,3-epoxypropoxy-azobenzene (EA) in N,N-dimethylacetamide/lithium chloride solution. The EA with epoxy group could highly efficiently react with cellulose to synthesize 3-azobenzyloxy-2-hydroxypropyl-cellulose (Azo-cellulose) ethers with controllable degree of substitution (DS(azo)). The DS(azo) was in a range of 0.2-2.0 adjusted by the molar ratio of EA to anhydroglucose unit of cellulose. The Azo-celluloses with DS(azo)≥0.53 were soluble in aprotic solvents like dimethylsulfoxide. Their chemical structures and properties were characterized by elemental analysis, FT-IR, NMR, and thermogravimetric analysis. They showed reversible trans-cis-trans transition when Azo-cellulose/DMAc solutions were irradiated by successive irradiation of UV and visible light. The transition between trans- and cis- isomers could be effectively controlled by simply adjusting the irradiation time. The photo-stimulated trans-cis-trans conformational change induced conformation transition between rod-like shape of trans-isomer and skewed shape of cis-isomer.
