Syntheses of four new pyridinium phenolates with caged phenolate functionalities as chromophores for quadratic optics
摘要:
Semi-empirical calculations as well as our preliminary studies indicate an increase of the nonlinear response of pyridinium phenolates with the raise of their interplanar angle. Unfortunately, the tendency of previously synthesized zwitterionic compounds to form aggregates prevents their use in electrooptical devices. In order to understand the process of aggregation and to circumvent it, the syntheses of new pyridinium phenolates bearing alkyl chains of various length, caging the phenolate functionality, have been achieved and are described herein.

Two new twisted pyridinium phenolates betaine dyes bearing phenyl or iso-propyl groups anchored at ortho positions of the phenolate function were synthesised. Their solvatochromism was investigated in detail. The results underscored the moderate protection provided by the two new substituents introduced, towards hydrogen bonding with hydroxylic solvents and highlight the true negative solvatochromism
