An organic-Ru2+ cluster-initiated dendritic faced metallo-octahedron and its unpredictable photoactivity†
Abstract
Herein, a novel 3D metal–organic ligand consisting of a folded Ru(II)-connected tetrameric cycle and two sets of 60° juxtaposed bisterpyridine arms was synthesized and its complexation with Zn2+ gave rise to dendritic-faced metallo-octahedron 6. Remarkably, octahedron 6 displayed unexpected photosensitization ability that could produce singlet oxygen (1O2) under white light irradiation.
