5-Arylvinyl-2,2'-bipyridyls: Bright "push-pull" dyes as components in fluorescent indicators for zinc ions.
TL;DR: The spectral sensitivity of bipy-containing fluoroionophores, such as AVBs, to zinc(II) can be exploited to prepare fluorescent indicators for this ion, and AVB moieties are incorporated in fluorescent heteroditopic ligands, so that the variation of zinc( II) concentration over a relatively large range can be correlated to fluorescence changes in either intensity or color.
