Optical thermometer based on the stability of a phosphorescent 6-bromo-2-naphthol/#alpha#-cyclodextrin_2 ternary complex

摘要

The phosphorescence lifetime of a water-soluble ternary complex of 6-bromo-2-naphthol and #alpha#-cyclodextrin has been found to decrease by more than two orders of magnitude over a 58deg C temperature range, which makes this molecular system well suited for use as the first optical thermometer based solely on phosphorescence lifetimes.
