Abstract

Herein is presented a new class of materials for second harmonic generation (SHG) -- organic inclusion complex, in which 'SHG-active units' (guest) are incorporated into chiral handle polycondensed anions (host) through short hydrogen bonds. The former can provide nonlinear optical response. The latter is expected to produce noncentrosymmetric structural 'molecular framework' and improve fundamental properties of materials such as thermal stability, mechanical strength and fabrication behavior, et al. Several new SHG active inclusion complexes were synthesized. In particular, optically fine bulk crystals of urea-(d)tartaric acid (UDT) and urea-(dl)tartaric acid (UDLT) have been obtained. They have good powder SHG intensity and short cutoff wavelengths.
