Abstract
Spiropyrans have been extensively investigated because of their thermo- and photochromic characteristics, but their biotherapeutic properties have not been explored much. We report anti-proliferative properties of a novel 3,3'-azadimethylene dinaphthospiropyran 11. Dibenzospiropyrans and dinaphthospiropyrans were synthesized by a simple and expedient method using acid-catalyzed aldol condensation of salicylaldehyde and 2-hydroxy-1-naphthaldehyde, respectively, with cyclic ketones. Together with structural elucidation by 2D NMR and X-ray crystallography studies, we provide a putative mechanism for their formation. Compound 11 showed solvatochromism and exhibited altered spectral characteristics depending on the pH. In acidic conditions, 11 remains in open form, whereas upon alkalinization it reverts back to closed form. Based on the in vitro anti-proliferative activity in H441, HCT-116, MiaPaCa-2, and Panc-1 cancer cell lines, 11 was submitted to further investigation. It reduced HCT116 colonosphere formation and demonstrated induction of caspase cascade, suggesting apoptosis. In vitro proliferation assays also suggested that HCl and trifluoroacetate salts of 11 are more effective. Treatment of mice carrying HCT-116 xenografts with 11 (5 µg/day, intraperitoneal for 3 weeks) suppressed tumor growth by 62%. Overall, the results reveal a new series of structurally complex, but relatively easy to synthesize molecules of which compound 11 represents a lead for anticancer development.

Abstract
A library of 12N,9-Diaryl 2-methyl-8-azaadenine (DAMA) compounds was designed and constructed through an aryl-pairing combination strategy for identifying a nucleobase-containing molecular switch that functions by the pH-regulated Dimroth rearrangement. By utilizing 2D thin-layer chromatography/mass spectrometry (2D-TLC-MS), the DAMA compounds were easily screened to identify which compounds could be used as molecular switches. The pH-switching ability of the DAMA was achieved by incorporating the acridine group as the key structural unit, as well as dual-modal colorimetric/fluorometric on/off properties as the probe functions. The real-time tracing of the switching process clearly indicated that the paired aromatics on both terminals of the DAMA molecule play a key role in tuning the switching kinetics.

Abstract
![]()
The relation between the chemical structure and the mechanical
behavior of molecular machines is of paramount importance for a rational
design of superior nanomachines. Here, we report on a mechanistic
study of a nanometer scale translational movement in two bistable
rotaxanes. Both rotaxanes consist of a tetra-amide macrocycle interlocked
onto a polyether axle. The macrocycle can shuttle between an initial
succinamide station and a 3,6-dihydroxy- or 3,6-di-tert-butyl-1,8-naphthalimide end stations. Translocation of the macrocycle
is controlled by a hydrogen-bonding equilibrium between the stations.
The equilibrium can be perturbed photochemically by either intermolecular
proton or electron transfer depending on the system. To the best of
our knowledge, utilization of proton transfer from a conventional
photoacid for the operation of a molecular machine is demonstrated
for the first time. The shuttling dynamics are monitored by means
of UV–vis and IR transient absorption spectroscopies. The polyether
axle accelerates the shuttling by ∼70% compared to a structurally
similar rotaxane with an all-alkane thread of the same length. The
acceleration is attributed to a decrease in activation energy due
to an early transition state where the macrocycle partially hydrogen
bonds to the ether group of the axle. The dihydroxyrotaxane exhibits
the fastest shuttling speed over a nanometer distance (τshuttling ≈ 30 ns) reported to date. The shuttling in
this case is proposed to take place via a so-called harpooning mechanism
where the transition state involves a folded conformation due to the
hydrogen-bonding interactions with the hydroxyl groups of the end
station.

Abstract
Spiropyran compounds are well known as an isomeric system, the closed spiropyran (SP) could be converted into the open merocyanine (MC) via acid-induced because stable protonated merocyanine (MCH) were formed by combination of MC and H+. In order to understand how the substituent affect the isomerization of spiropyran. A series of the chromene 7-subsituted spiropyran compounds were designed and synthesized. The photophysical properties of them were studied comparatively by UV-absorption and fluorescence spectra in different pH. The results demonstrated that the various substituents influenced not only the photophysical properties of SP, MC and MCH forms, but also the pKa of the MC-MCH transformation. There was a good linearity relationship between the pKa and the Hammett constant of substituent, the pKa was smaller when the Hammett constant of substituent was larger.

Abstract
The thermal and photochemical reactions of a newly synthesized complex, [Ru(II)(TPA)(tpphz)](2+) (1; TPA=tris(2-pyridylmethyl)amine, tpphz=tetrapyrido[3,2-a:2',3'-c:3'',2''-h: 2''',3'''-j]phenazine), and its derivatives have been investigated. Heating a solution of complex 1 (closed form) and its derivatives in MeCN caused the partial dissociation of one pyridylmethyl moiety of the TPA ligand and the resulting vacant site on the Ru(II) center was occupied by a molecule of MeCN from the solvent to give a dissociated complex, [Ru(II)(η(3)-TPA)(tpphz)(MeCN)](2+) (1', open form), and its derivatives, respectively, in quantitative yields. The thermal dissociation reactions were investigated on the basis of kinetics analysis, which indicated that the reactions proceeded through a seven-coordinate transition state. Although the backwards reaction was induced by photoirradiation of the MLCT absorption bands, the photoreaction of complex 1' reached a photostationary state between complexes 1 and 1' and, hence, the recovery of complex 1 from complex 1' was 67%. Upon protonation of complex 1 at the vacant site of the tpphz ligand, the efficiency of the photoinduced recovery of complex 1+H(+) from complex 1'+H(+) improved to 83%. In contrast, dinuclear μ-tpphz complexes 2 and 3, which contained the Ru(II)(TPA)(tpphz) unit and either a Ru(II)(bpy)2 or Pd(II)Cl2 moiety on the other coordination edge of the tpphz ligand, exhibited 100% photoconversion from their open forms into their closed forms (2'→2 and 3'→3). These results are the first examples of the complete photochromic structural change of a transition-metal complex, as represented by complete interconversion between its open and closed forms. Scrutinization by performing optical and electrochemical measurements allowed us to propose a rationale for how metal coordination at the vacant site of the tpphz ligand improves the efficiency of photoconversion from the open form into the closed form. It is essential to lower the energy level of the triplet metal-to-ligand charge-transfer excited state ((3)MLCT*) of the closed form relative to that of the triplet metal-centered excited state ((3)MC*) by metal coordination. This energy-level manipulation hinders the transition from the (3)MLCT* state into the (3)MC* state in the closed form to block the partial photodissociation of the TPA ligand.

Abstract
Mechanically interlocked molecules, such as catenanes and rotaxanes, are at the heart of the development of molecular machines chemistry. They are able to self-organize, self-assemble, and self-control themselves into new materials with potential application as molecular devices. In this review, an overview of some recent progress on molecular machines is given, including new methodologies for their synthesis and self-assembly and their recent applications as dual or multilevel fluorescent molecular switches, as potential sensors, and even as a molecular-level transporter. In one development, a molecular machine containing a charge-transfer chromophore was designed to generate controllable aggregate structures through the reversible movement of a macrocycle over a thread; this was done in order to better understand the application of a molecular shuttle in solid state. Light is shed on how the novel properties and functions of molecular machines are extended, and examples of the ways in which molecular machines have been applied to the design and process of intelligentized systems are provided.

Abstract
Intense current interest in supramolecular chemistry is devoted to the construction of molecular assemblies displaying controlled molecular motion associated to recognition. On this ground, molecular clips and tweezers have focused an increasing attention. This tutorial review points out the recent advances in the construction of always more sophisticated molecular clips and tweezers, illustrating their remarkably broad structural variety and focusing on their binding ability towards neutral guests. A particular attention is brought to recent findings in dynamic molecular tweezers whose recognition ability can be regulated by external stimuli. Porphyrin-based systems will not be covered here as this very active field has been recently reviewed.
