SECOND-ORDER NONLINEAR OPTICAL COMPOUND AND NONLINEAR OPTICAL ELEMENT COMPRISING THE SAME
Problem to Be Solved: to provide a chromophore having a far superior nonlinear optical activity to conventional chromophores and to provide a nonlinear optical element comprising said chromophore. Solution: a chromophore comprising a donor structure D, a π-conjugated bridge structure B, and an acceptor structure A, the donor structure D comprising an aryl group substituted with a substituted oxy group; and a nonlinear optical element comprising said chromophore.

Effect of modified donor units on molecular hyperpolarizability of thienyl-vinylene nonlinear optical chromophores
Highly efficient and thermally stable nonlinear optical chromophores based on the phenyl vinylene thiophene vinylene (FTC) donor-π-acceptor structure have been synthesized and investigated. The donor part of the chromophores was modified with additional d
