Yw. Cao et al., A NEW SERIES OF NONLINEAR-OPTICAL ORGANIC MATERIALS WITH MOLECULAR RECEPTOR - DESIGN AND SYNTHESIS, Synthetic metals, 71(1-3), 1995, pp. 1733-1734
The series of compounds ( BI-III) containing a NLO chromophore, bearin
g a barbituric acid unit as molecular receptor, and their complementar
y substrate - melamine derivatives (MI-II), have been synthesized. BI-
III have been found to display efficient optical second harmonic gener
ation.
