ALPHA-CYANOCINNAMIC ACID ESTER-BASED COMPOUND AND ORGANIC NONLINEAR OPTICAL MATERIAL COMPOSED OF THE SAME COMPOUND

摘要

PURPOSE: To obtain the subject new compound, having large nonlinear optical effects, stable at ambient temperature, excellent in resistance to damage by light and useful as organic light-emitting materials, laser dyes, nonlinear optical materials, etc. ;CONSTITUTION: A compound, e.g. 1'-methylpropyl (S)-2-cyano-3-(4-aminophenyl)-2- propenate of formula I [D is NH₂, N(CH₃)₂, N(C₂H₅)₂, etc.; R is CH or CH=CH- CH; R' is formula II to IV]. The compound of formula I is obtained by carrying out condensing reaction of sec-butyl (S)-cyanoacetate, 1'-methylheptyl (R)- cyanoacetate, 1'-phenylethyl (R)-cyanoacetate, etc., with the corresponding aromatic aldehyde (e.g. p-aminobenzaldehyde).;COPYRIGHT: (C)1993,JPO&Japio
