Regulation of intra- and intermolecular Pt–Pt and π–π interactions of a U-shaped diplatinum complex to achieve pseudo-polymorphic emissions in solution and crystalline states

Abstract

Pseudo-polymorphic emissions of a U-shaped di-[Pt(NCN)] complex were achieved in crystalline and solution states by regulating the intramolecular conformation (open or closed) and intermolecular stacking mode (with or without Pt–Pt interaction).
