Abstract
Abstract New thermally irreversible photochromic methyl cyanoacetate-condensed fulgide derivatives were prepared and their photochromic properties were investigated. Coloured form of methyl cyanoacetate-condensed derivatives C - 4 ( a – d ) show large bathochromic shifts of their long wavelength absorption bands compared to the coloured form of corresponding fulgides Z - 1 ( a – d ). Solvent effects on the compound ZZ - 4a and its ring-closed form C - 4a were investigated. The polarity of the solvent caused a bathochromic shift of both coloured and uncoloured forms.
