Abstract

Highly efficient frequency conversion in crystalline organic molecules for opto-electronic applications is the aim of the investigation reported here into how various heteroatomic rings affect molecular nonlinearity. The optical properties of hydrazone derivatives with the furan or thiophene moiety as part of the conjugated core are described, and 5-(methylthio)thiophenecarboxaldehyde-4-nitrophenyl-hydrazone (MTTNPH) is demonstrated to have the properties required.
