摘要：

The reaction between malononitrile dimer and 1,3-dithiole-derived polyenals affords push-pull systems with (Z)-geometry around the newly formed C=C bond. In one instance, an unexpected shortening of the merocyanine chain takes place. These push-pull derivatives have weakly alternated structures and moderate optical nonlinearities, which can be modified by functionalization of the amino group. (C) 2007 Elsevier Ltd.
