Aky. Jen et al., DESIGN AND SYNTHESIS OF THERMALLY STABLE SIDE-CHAIN POLYIMIDES FOR 2ND-ORDER NONLINEAR-OPTICAL APPLICATIONS, Journal of the Chemical Society, Chemical Communications, (23), 1994, pp. 2711-2712
Novel Mitsunobu and tricyanovinylation reactions have been employed to
incorporate efficient nonlinear optical chromophores as side-chains i
nto aromatic polyimides resulting in high electro-optic activity and l
ong-term alignment stability at 100 degrees C for more than 500 h.
