A STUDY ON THE FLUORESCENCE EMITTING PROP ERTIES OF PYRENE DERIVATIVE

In this work, a new pyrene derivative pyrenyl chalaone(PD) has been sy nthesized and its steady - state photophysical properties in solution and micell systems have been studied. Results indicated that the inter molecular charge transfer complexes (Inter - CT) between PD molecules are very easy to form even if the concentration is very low. The fluor escence emission of PD comprises the fluorescences from pyrenyl monome r, intramolecular charge transfer state (Intra - CT) and intermolecula r charge transfer state complex. The compound PD has good solvatochrom ism effect, concentration effect and temperature effect, and is a bett er probe molecule for microenvironment.
