Effecient synthesis and decomposition study of optically nonlinear adducts of tetracyanoquinodimethane
摘要:
Described are the synthetic conditions resulting in a significant improvement in both yield and reaction time of Z-beta-(1-substituted-4-pyridinium)-alpha-cyano-4-styryldicyanomethanide chromophores. A decomposition study of the zwitterionic chromophores in solution is also described. (C) 2003 Elsevier Science Ltd. All rights reserved.

A non-linear chromophore is obtained by reacting a picolinium halide having a desired functional group (preferably —OH) with a lithium TCNQ adduct. If desired, the chromophore can be graft polymerized onto a polymer which has complementary functional groups (preferably carboxyl groups). Optionally the polymer can then be cross-linked. Such polymers are useable in electro-optical devices.
