pH值对3-羟基-2-萘甲酸荧光性质及其β-环糊精包结物生成常数的影响

EFFECT OF pH VALUES ON THE FLUORESCENCE OF 3 HYDROXY 2 NAPHTHOIC ACID AND THE FORMATION CONSTANTS OF ITS INCLUSION COMPLEX WITH β CYCLODEXTRIN

研究了不同ｐＨ值３羟基２萘甲酸的荧光性质，并用荧光双倒数法测定了３羟基２萘甲酸与β环糊精包结物在不同ｐＨ值的生成常数，结果表明疏水作用和氢键对包结物的形成起重要作用。

The effect of pH values on the fluorescence of 3 hydroxy 2 naphthoic acid were studied and the formation constants of its inclusion complex with β CD were determined. Our results indicate that the hydrophobic interactions and hydrogen bonding play an important role in the formation of the inclusion complex. [WT5”HZ]
