Abstract:	The synthesis of three cyano-substituted divinyleneπ-gelators is reported. The modulation of the color is achieved by placing the cyano groups in appropriate position of the conjugated backbone, thus modulating the donor−acceptor interaction. Variable-temperature UV−vis data have been utilized to investigate the self-assembly of the gelators1−3that is governed by a cooperative mechanism. A complete set of photophysical parameters (ΦF ,τ, kr andknr) demonstrate the role of the molecular aggregation in enhanced emission upon self-assembly
