Title:
NONLINEAR OPTICAL MATERIAL
Document Type and Number:
Japanese Patent JPH04223449
Kind Code:
A
Abstract:
PURPOSE:To improve nonlinear optical, performance by using 2,6-dibromo-N,N- dimethyl-4-nitroaniline. CONSTITUTION:2,6-Dibromo-N,N-dimethyl-4-nitroaniline represented by formula I is used. This compd. has a nitro group as an acceptor group and a dimethylamino group as a donor group in the structure. Since the acceptor and donor groups are separated by a benzene ring, large dipole moment especially in an excited state is obtd. and high nonlinear sensitivity is ensured. Since two Br atoms are introduced, the compd. has low sublimability.
