Abstract
Absorbance and fluorescence characteristics of 10-hydroxybenzo[h]quino line (HBQ) are studied in the presence of alpha-, beta-, and gamma-cyc lodextrins, and the surfactants, hexadecyltrimethylammonium bromide (C TAB), sodium dodecyl sulfate (SDS), and polyoxyethylene(23) lauryl eth er (Brij 35). Fluorescence measurements are used to investigate the ef fect of organized media on the excited-state intramolecular proton tra nsfer (ESIPT) reaction of HBQ by monitoring the large Stokes-shifted t automer emission. Absorbance measurements are used to further characte rize the interactions of HBQ with the various media.
