A functionalized ruthenium(II)-bis-terpyridine complex as a rod-like luminescent sensor of zinc(II)

Abstract

The nearly non-luminescent ruthenium(II)-terpyridine chromophore, functionalized with an uncoordinated terpyridine fragment, 2, undergoes Zn(II)-induced association leading to a luminescent rod-like 2 : Zn²⁺ : 2 species with a luminescence enhancement factor, EF ⩾ 10.
