The photophysical behaviour of a new pyrene derivative, 1-(4-N,N-dimethylaminophenylethynyl) pyrene (DMAPEPy), in various solvents has been studied. Due to the presence of an ethynyl link with a cylindrical π cloud between the donor (N,N-dimethyl group) and the acceptor (pyrene), the molecule shows efficient intramolecular charge transfer, with a high extinction coefficient in all the solvents. There is significant solvatochromism in the fluorescence with a large increase in the Stokes' shift of around 125 nm between n-hexane and acetonitrile. The solvent-dependent spectral data show a good correlation with the Kamlet–Taft solvent polarity parameter (π*). The plots of Stokes' shifts with ET (30) are linear for non-protic solvents ...
