Platinadithiolene-conjugated pyrylium salt with strong intramolecular donor–acceptor interaction†
Abstract
Protonation of a new platinum complex, Pt(1-pdtAq)(tBu2bpy), where 1-pdtAq is 1-(phenyldithiolenethynyl)anthraquinone, afforded a cyclized structure, [Pt(1-pdtPyl)(tBu2bpy)]+, with a unique electronic structure due to intense intramolecular charge transfer.
