A series of pyrylium compounds with different structures have been synthesized. The photophysical behavior of these compounds has also been measured. Results show that the structures of compounds and the polarities of solvents make great effects on the photophysical behaviors of compounds, especially when the structures of compounds are hindered. It indicats that the intramolecular rotation relaxation of compounds in excited state in closely related to the fluorescence quantum yields of compounds.
