Abstract:
We report the observation of reentrant nematic behavior in a relatively new class of compounds, namely, dimerlike mesogens that are made by covalently linking nematogenic cyanobiphenyl and nonmesogenic N-(n-alkyl)salicylaldimine segments through a central flexible spacer of varying length and parity. The existence of reentrant phenomenon in this class of mesogens, evidenced indubitably by means of several complementary studies, appears to be crucially dependent on the length of the terminal alkyl tail and parity of the spacer.
