文摘

A series of upper-rim diphosphinated calixarene receptors bearing various R and R′ substituents at the lower rim (Lⁿ; n = 1−5) were synthesized, and their reactions with [Pt(Thpy)(HThpy)Cl] afforded the phosphorescent platinum(II)-modified calixarene receptors [(PtThpyCl)₂Lⁿ]. The structure of [{PtThpy(CH₃CN)}₂L¹](ClO₄)₂ and [(PtThpyCl)₂L⁵] were determined by X-ray crystallographic analysis, and the photophysical properties of [(PtThpyCl)₂Lⁿ] were investigated.
