ABSTRACT:
An organic material for non-linear optics, in which the structure of the molecule includes an electron donor group and an electron attractor group connected by means of an electron-transmitting group, the material being characterized by the fact that it satisfies the formula: ##STR1## where R is selected from (CH.sub.3).sub.2 N and CH.sub.3 O, with the first material being dimethylamino 4, cyano 4' biphenyl and the second being methoxy 4, cyano 4' biphenyl.
