Abstract: Two photochromic coumarin-based dithienylethenes were synthesized by one-pot nucleophilic addition reaction of alkyne and phenol. Both diarylethenes exhibited reversible photochromism, but their conformation played an important role in their photochromic properties. The derivative with high… read more here.

DOI: 10.1007/s11172-018-2242-0
Abstract: New benzoxazolyl-substituted spiroindoline-benzopyrans with electron-withdrawing groups in the indoline fragment were obtained. These compounds exhibit positive P- and T-type photochromism. Structural correlations of the spectrokinetic properties depending on the variation of substituents in the indoline… read more here.

DOI: 10.1021/acs.organomet.9b00165
Abstract: Photolysis of thioureido derivatives of cymantrene in solution and solvent-free affords stable six-membered dicarbonyl chelates due to coordination of sulfur of the C═S group to manganese. The process is accompanied by a color change and… read more here.

DOI: 10.3390/molecules27238492
Abstract: New salts of photochromic indoline spiropyrans capable of reversibly responding to UV radiation were synthesized to develop light-controlled materials. Photoinduced reactions of the synthesized compounds were studied using absorption and luminescence spectroscopies, and the quantum… read more here.
