ABSTRACT:
A nonlinear optical material comprises a solid solution of an organic guest compound having an electron donative group or an electron attractive group. The organic guest compound is contained in the nonlinear optical material preferably an oriented form through orientation under melting by application of a DC electric field. The guest compound is preferably a para-di-substituted benzene derivative represented by the formula: ##STR1## wherein A is an electron donative group and B is an electron attractive group.
