On the solvatochromic reversal of merocyanine dyes. Part 2.1 An experimental and semi-empirical study of the solvatochromism of ?- and ?-vinylogous pyridones

Aliaga C.; Galdames J.S.; Rezende M.C.


The vinylogous ?-pyridone 1,2-dihydro-1-(4-methoxyphenyl)-2-(4-oxocyclohexa-2,4-dienylidene)-4,6- diphenylpyridine 3 was prepared and its solvatochromic behaviour in several solvents recorded and compared to that of its ?-isomer 1. The relative behaviour of these dyes, which differed from that of other solvatochromic vinylogous ?/f?-pyridones, could be reproduced by a previously described theoretical model.
