The photophys. behaviors of QCH:CHC(O)CH:CHQ (Q = 4-Me2NC6H4), compound I and compound II, in which the central parts of mols. are restricted have been investigated. Compound with central 5 member rings possesses higher fluorescence quantum yield than that of central 6 member ring. As for the effect of medium viscosity on the fluorescence quantum yields of these compounds, it was discovered that compound with central 6 member ring is the most susceptible one to the change of medium viscosity. All of these interesting phenomenon have been discussed briefly.
