Self-assembly of amphiphilic fluorescent dyes showing aggregate-induced enhanced emission: temperature dependence of molecular alignment and intermolecular interaction in aqueous environment.
A 1-cyano-1,2-bis(biphenyl)ethene derivative having hexa(ethylene glycol) groups as amphiphilic side chains showed aggregate-induced enhanced emission in water; upon heating the intensity of the enhanced emission was attenuated in a lower temperature range than the temperature range where exciton interaction is still effective.
