Abstract

Recent developments on three different types of molecular crystals are presented. The first, the ionic molecular crystal 4-N,N-dimethylamino-4′-N′-methyl-stilbazolium tosylate (DAST), has demonstrated phase-matched second harmonic generation and a high electro-optic coefficient. Two kinds of co-crystals based on short hydrogen bonds represent the second class. In this class, the vector parts of the first order hyperpolarizabilities are almost completely parallel to each other, which is an ideal alignment for electrooptics. For the last class, the hydrazone derivatives, the probability of forming acentric crystal is as high as 71%, and 25% of them exhibit a very strong signal in the second harmonic powder test.
