Abstract

Stepwise synthesis of nanosized Pd-Ru heteronuclear metal-organic cages from predesigned redox- and photo-active Ru(II)-metalloligand and naked Pd(II) ion is described. The resulting cage shows rhombododecahedral shape and contains a 5350 Å(3) cavity and 12 open windows, facilitating effective trapping of both polar and nonpolar guest molecules. Protection of photosensitive guests against UV radiation is studied.

摘要

分步合成纳米 Pd-Ru 杂核金属有机笼,由预先设计的氧化还原和光活性 Ru(II)-金属配位体和裸露的 Pd(II)离子组成。所得笼具有菱十二面体形状,包含一个 5350 Å(3)的空腔和 12 个开口窗,有利于有效捕获极性和非极性客体分子。研究了对光敏客体的保护作用,以防止其受到 UV 辐射。
