A NEW KIND OF SURFACTANT:LONG-CHAIN ALKYLTRIPHENYLPHOSPHONIUM HALIDES Ⅲ.AN“ABNORMAL”QUENCHING OF PYRENE FLUORESCENCE BY PHOSPHONIUMS WITH DIFFERENT LENGTHS OF ALKYL CHAIN

Received Date: 14 May 1990

A study of the quenching of pyrene fluorescence by a series of alkyltriphenylphosphonium bromides indicated the coiling conformation of ionic surfactant in aqueous solution. Formation of pyrene excimer in cetyltriph-enylphosphonium solution strengthened the conclusion.
