Abstract
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.
