Title:
NONLINEAR OPTICAL MATERIAL
Document Type and Number:
Japanese Patent JPH05142603
Kind Code:
A
Abstract:
PURPOSE:To obtain a low mol.wt. org. material having x<(3)> equal to or larger than that of pi conjugate polymers by using such an org. material having substitution of alkyl amino groups for both ends of the molecule and two or more specified conjugate bonds. CONSTITUTION:This material has substitution of alkyl amino groups for both ends of the molecule and two or more -CH=CH-CO as conjugate bonds. The material has high x<(3)> which exceeds 10<-10> esu, and is a pi-conjugate compd. having a symmetric structure with substitution of electron donating groups (donors) at both ends of the molecule. By using this material to constitute a principal-chain or side-chain polymer material, for example, with even 50mol% introduction rate, a material having high light transmitting property and formability can be produced since the low mol.wt. material can be easily coupled with a polymer material having excellent light transmitting property and formability.
