S. Sakagami et al., Liquid crystalline properties and photochromism of 4-alkyl-N-(4-alkloxysalicylidene) anilines, LIQ CRYST, 28(8), 2001, pp. 1199-1202
Eight new homologous series of 4-alkyl-N-(4-alkloxysalicylidene) anilines w
ere synthesized. The phase transitions of these homologues were determined
using differential scanning calorimetry and polarizing optical microscopy.
The homologues began to exhibit liquid crystalline phases as the terminal a
lkyl or alkoxyl chains were lengthened. In addition, some members of these
homologues series exhibited photochromism in the solid state.
