摘要：

The vinylogous alpha-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 gamma-isomer 1. The relative behaviour of these dyes, which differed from that of other solvatochromic vinylogous alpha/gamma-pyridones, could be reproduced by a previously described theoretical model.
