Second-sphere coordination-induced morphology transformation from phosphorescent nanowires to microcubes†
Abstract
Nanowires of a pyridyl-functionalized iridium complex are transformed into microcubes as a result of hydrogen-bond-assisted second-sphere coordination between pyridyl groups and monovalent anions of 1,3,5-benzenetricarboxylic acid (H2BTC−). This is accompanied by a blue-shift of the phosphorescence from 662 to 638 nm.
