抄録

Amphiphilic pyranines POC<I>n</I> (<I>n</I> = 8, 12, and 16) were synthesized, and their aggregation behaviors were investigated in water. <SUP>1</SUP>H NMR studies implied that POC16 existed in the conformation of the pyranine chromophore wrapped with a hexadecyl methylene chain, which showed no indication of aggregation at the concentration up to 10<SUP>−4</SUP> M. However, the formation of micelles was readily induced by the addition of methylviologen (MV<SUP>2+</SUP>) to a POC16 solution, which was responsible for an apparent large complexation constant of ca. 10<SUP>6</SUP> M<SUP>−1</SUP>.
