Article Abstract
Platinum complexes aggregate into polymorphs with different intermolecular interactions leading to different photophysical properties. Strong intermolecular interactions stabilize the aggregate to such an extent that the polymorphs can be separated directly by column chromatography. Solid-state structures as well as quantum-chemical calculations confirmed the effect of the interactions on the photophysical properties.

A simple yet efficient method involving a visible-light-induced direct, regioselective chalcogenation of indoloquinoxaline derivatives has been developed. Thiols, disulfides and diselenides were found to be efficient as chalcogenating agents in the presence of Rose Bengal as a photosensitizer. This photoinduced C-H functionalization a cross-dehydrogenative-coupling (CDC) protocol was carried out at ambient temperature under an open-air atmosphere.

Rhodamine derivatives exhibiting inverted open-closed form fluorescence behavior redefines conventional photochemical paradigms while illuminating new structure-property relationships and fascinating application potentials. Herein, we report a donor-acceptor engineering strategy that activates closed form emission in rhodamines, achieving unprecedented Stokes shifts (>280 nm) while overcoming aggregation-caused quenching. The new class of rhodamines with inverted open-close form emission behavior are created through simultaneous substitution of N,N-diethyl groups with indole (donor) and conversion of spiro-lactam to benzene sulfonamide (acceptor).

The fine-tuning of the (photo)physical properties of molecular photoswitches remains an active area of research, and recently, the incorporation of heterocycles into photoswitch scaffolds has emerged as an effective strategy in this vein. To assess the influence that heterocyclic rings have on hydrazone-based systems, we synthesized a series of photoswitches and examined the impact that heterocycles have on the switching efficiency. TD-DFT calculations and structure-property analyses revealed that heterocycles with basic nitrogen and secondary hydrogen-bonding sites (e.

The aim of the present review is to provide a systematic survey on the recent advancements in the chemical synthesis of thiochromones, thiochromanones, the less explored thiochromene-4-thiones and some analogs. These compounds are used as versatile building blocks in the synthesis of other complex and polycyclic heterocyclic analogs. Highlights on biological and photophysical properties of these thio derivatives are also included and discussed.
