Abstract

The change in cave micro-invironment of β-cyclodextrin (β-CD) caused by methylation was investigated by using the twisted intramolecular charge transfer (TICT) of sodium diethylaminobenzoate (SDEAB) and sodium dimethylaminobenzoate (SDMAB) as fluorescent probes. The results indicte that the nonpolar β-CD cavity favors the formation of the TICT state of dialkylaminobenzoic acid-type molecules. It was demonstrated that the TICT fluorescence of SDEAB (or SDMAB)-β-MCD (methylated β-cyclodextrin) system could be used to detect methanol in aqueous solution.

Key words: METHANOL, CYCLODEXTRIN, CHARGE TRANSFER
