ABSTRACT:
Disclosed are polymers which contain NLO dye moieties based upon a barbituric acid group, a thiobarbituric acid group or a 1,3-bis(dicyanomethylene)indan-2-ylidene group. These polymers, after poling, are useful in NLO elements in devices employing nonlinear optics. Also disclosed are various intermediates used in making such polymers.
