Autor: M. S. Lyubich, L. N. Yashukova, L. V. Zhirova, Yu. M. Karpova, E. B. Lifshits, R. A. Gershtein, S. M. Larina
Publikováno v: Chemistry of Heterocyclic Compounds. 20:665-668
Dimethylidynemerocyaninocyanines — substituted benzimidazole derivatives — were synthesized. A decrease in the basicity of the benzimidazole ring with intensification of the electronegative properties of the substituent gives rise to a small (up

Correlation of polymethine dye basicity with parameters of the terminal heterocyclic nuclei
Autor: Yu. M. Karpova, Lifshits Eh B, M. N. Ushomirskii
Publikováno v: Chemistry of Heterocyclic Compounds. 25:1071-1078
The basicity values of symmetrical polymethine dyes have been compared and correlated with a variety of parameters obtained both experimentally or derived by calculations, as well as with parameters obtained by quantum mechanical methods, characteriz
