Preferential solvation of an ILCT excited state in bis(terpyridine-phenylene-vinylene) Zn(II) complexes

The excited state of terpyridine derivatives of phenylene-vinylene fragments chelating Zn(II) show a strong solvatochromism (up to 56 nm) upon preferential solvation by polar solvents of an intraligand charge transfer state.
