Luminescent complexes with ligands containing C=N bond

Data on luminescent complexes with azomethine ligands are generalized and systematized. The synthesis and luminescent properties of complexes with acyclic and cyclic azomethines are considered.

New photochromic nonsymmetric bis-spiropyran of the 2,3-dihydro-4-oxonaphtho[2,1-e][1,3]oxazine series

New nonsymmetric bis-spiropyran of the 2,3-dihydro-4-oxonaphtho[2,1-e][1,3]oxazine series was prepared. On the basis of the results of photochemical study and quantum-chemical calculations, it has been shown that both pyran cycles experience opening during irradiation of a bis-spiropyran solution with unfiltered light.

Photo- and thermochromic spirans. 35.* Synthesis and photochromic properties of spiro[indoline-2,3′-pyrano[3,2-f]quinolines] and their cationic derivatives

New photochromic spiropyranoquinolines and their cationic derivatives have been synthesized. Quaternization of the quinoline fragment leads to significant enhancement of the thermal stability of the merocyanine isomers of these cationic spiropyrans.

Photo- and thermochromic spirans 36.* Synthesis, structure and photochromic properties of 7',7"-{1,4-phenylenedi(methylene)-bis(5-chloro-1,3,3-trimethyl-1,3-dihydrospiro-[indole-2,3'-pyrano[3,2-f]quinolinium])} diiodide

A synthesis is reported for a new photochromic indoline bisspiropyran salt containing a quinoline fragment. This compound exists as a racemic mixture. The photochromic properties of this symmetrical bisspiropyran were studied.
