SECOND-ORDER NON-LINEAR OPTICAL COMPOUND AND NON-LINEAR OPTICAL ELEMENT COMPRISING SAME

摘要

Disclosed are: a chromophore having a dramatically superior non-linear optical activity compared to conventional chromophores; and a non-linear optical element comprising the chromophore.Specifically disclosed are: a chromophore comprising a donor structure moiety (D), a π-conjugated bridge structure moiety (B) and an acceptor structure moiety (A), wherein the donor structure moiety (D) contains an aryl group substituted by a substituted oxy group; and a non-linear optical element comprising the chromophore.
