Abstract

The synthesis and characterization of macrocyclic Pd(II)/Pt(II) dimers and their monomeric precursors with diphosphine spacer Ph 2P–CC–PPh 2 (C 2P 2) are reported. Their excited-state properties, including solvent-dependent absorption, emission and quantum yield, are studied. When the solvent polarity increases, solvatochromic absorption band shifts to higher energy, emission maximum shifts to lower energy, and quantum yield decreases. In addition, the host–guest behavior of these new inorganic macrocycles is also reported here.
