Trans-4-(p-N,N-dimethylaminostyryl)-N-vinylbenzylpyridinium chloride (1) is a newly synthesised multichromophore chemosensor. This molecule displays strong intramolecular charge transfer properties. It fluorescences in a very favourable region (480-650 nm in polar and viscous solutions) for its use as a sensing system. Steady-state and time-resolved fluorescence spectroscopy have been used to characterize photophysical properties in viscous and non-viscous polar solutions. We investigated the influence of solvent viscosity on the rate constants of radiative and non-radiative processes of deactivation of (1) in aqueous solutions.
