Abstract

In a 25% methanolic aqueous solution the metal ion specificity of ratiometric fluorescence response of a bis-anthrylpolyamine host is increased versus a purely aqueous medium. It is proposed that the geometry of the host, metal ion size, and hydrophobicity work in concert to give the geometry leading to excimer fluorescence.
