Laboratory of photochemistry and luminescence
Head of the Laboratory: Prof. Anatoly V. Metelitsa
The laboratory had been based in 1970 and ever since it had a lot of research experience in organic photochemistry and luminescence. The scientific results have been recognized both in Russian Federation and abroad. The first head of laboratory was professor M. I. Knyazhansky. The laboratory researchers have received original materials on spectral properties, structural and energetic mechanisms of photoinduced processes of photochromic molecules such as pyrans, chromenes, spiropyrans, spiroxepines, fulgides, diarylethens, o-hydroxyazomethines, aryloxyquinones, aryl-substituted cations of pyridinium, pyrimidinium and pyridine, as well as photo- and thermochromic spiro-1,3-oxazines, fulgides of indoline series, bipolar spiro-σ-complexes and new series of photo-, thermo- and electrochromic perimidinespirohexadienones unknown previously. The important finding in this field was the discovery of photochromic properties of benz-1,3,2-oxazaborines and bis-(N-alkyl- or aryl-)salicylal-diminates that are metal analogues of 2H-chromenes and sym-spirooxazines respectively.
