Summary: In this study, a series of new photochromic compounds with near-infrared (NIR) absorption and fluorescence were synthesized. These compounds have conjugated cationic 3H-indolium substituents in different positions of the 2H-chromene moiety. The electron-donating methoxy groups were introduced to form an effective conjugation chain, enabling NIR absorption and fluorescence. The compounds demonstrated positive or negative photochromism depending on the position of the cationic fragment, and one of the compounds showed bidirectional photochromic properties induced by visible light of different wavelengths. The photoinduced merocyanine forms of the compounds exhibited far-red shifted absorption maxima and NIR fluorescence, making them potential fluorescent probes for bioimaging.

Summary: Novel photochromic spiropyrans with fluorine substituents and cationic fragments or formyl groups were synthesized using a simple one-pot method. The structural- related photochromic transformations of the studied SPPs include positive, negative, and balanced photochromism effects, depending on the substituents at different positions on the molecule.

Summary: A directed synthesis of the first nitrile-rich dye showing visible-light-induced negative photochromism in aqueous medium was successfully achieved, demonstrating the color change of an aqueous solution from yellow to magenta by varying pH. The synthesized dye was found to be a thermally unstable photochrome that could be controlled by pH regulation, revealing a new direction in the investigation of nitrile-rich negative photochromes.

Summary: Indoline spiropyrans with conjugated cationic vinyl-3H-indolium fragment and their analogues with formyl substituent in the 2H-chromene moiety were synthesized using a simple one-pot method. The structures of the compounds were confirmed using various analytical techniques, including single crystal X-ray. Photochromic properties were studied, showing that electron-withdrawing substituents stabilize merocyanine isomer effectively, while certain substituents can suppress photochromic behavior.

Summary: Stilbenes (diphenylethenes) are widely used organic chromophores, but their stability under irradiation is a concern. Heteroarylethenes, on the other hand, offer improved stability and increased speed of thermal back reaction. In this study, we investigate the isomerization kinetics of rationally designed heteroarylethenes and their chemical architecture's impact on the speed of the process.

Summary: This study presents a type of macrocycle with stiff-stilbene-containing structure that can undergo photoinduced isomerization between (Z)- and (E)-isomers. The macrocycles can effectively form pseudorotaxane complexes with pyridinium halide axles, which can be tuned by varying the templating counteranion. However, the threading capability of axles is significantly reduced upon light-induced isomerization. Additionally, the axle component can dynamically relocate between the macrocycle and a secondary isophthalamide host, triggered by light irradiation.

Summary: Organic photochromic compounds are currently of great interest for use in photopharmacology, targeted drug delivery, and bio-imaging. The synthesis of two novel molecular hybrids of indoline spiropyrans and alpha-lipoic acid via an esterification reaction was reported in this study. Photochemical studies revealed the photochromic activity of the spirocompounds, while cytotoxicity tests on HeLa cell cultures showed unpredictable biocompatibility of the hybrids compared to their parent substances. Flow cytometry results demonstrated that the hybrids induced an antioxidant response in model cells, indicating emergent biochemical and signaling antioxidant properties.

Summary: Coordination chemistry is a powerful method for synthesizing supramolecular cages with specific applications. This study successfully synthesized discrete, homochiral (Fe2L3)-L-II cages through chirality-driven self-assembly. The size of these cages can be controlled by stereochemical manipulation of the iron(II) centers, and their formation requires chirality at both the vertices and ligand backbones. The smaller cages exhibit stereoselectivity with only chiral ligands, and their formation is driven by non-covalent interactions.

Summary: Self-reproducing lipids can initiate, sustain and accelerate the movement of octanol droplets in water. Reciprocally, the chemotactic movement of the octanol droplets increases the rate of lipid reproduction substantially. This coupling between molecular chemistry and microscopic motility offers alternative means of performing work and catalysis in micro-heterogeneous environments.

Summary: In this study, the optimal conditions for producing active haloacid dehalogenase by E. coli BL21 (DE3) carrying a recombinant plasmid were investigated, leading to the identification of specific conditions that resulted in successful degradation of monochloroacetic acid (MCA) and production of chloride ions. The expression of the protein was influenced by inducer concentration, pre-induction incubation time and temperature, as well as induction time and temperature, while MCA concentration and medium pH affected the ability of the recombinant strain to grow in a toxic environment. These findings provide a foundation for further exploration of dehalogenases for MCA biodegradation.
