Abstract
The synthesis of three cyano-substituted divinylene π-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 gelators 1-3 that is governed by a cooperative mechanism. A complete set of photophysical parameters (ΦF,τ, kr and knr) demonstrate the role of the molecular aggregation in enhanced emission upon self-assembly.
