Article Abstract

Two novel -Re(CO)-based rectangles {[(CO)Re(μ-Cl)Re(CO)](μ-L)} () and {[(CO)Re(μ-OCH)Re(CO)](μ-L)}() based on new photochromic dithienylethene-containing ligand 2,7-di(pyridin-4-yl)-9,10-bis(5-chloro-2-methylthien-3-yl)-phenanthrene () were prepared. They displayed varying photochromic properties both in solution and in the single-crystal state. Through a judicious choice of the bridging ligands along the short sides of the rectangles, the photophysical and electrochemical properties of the complexes could also be readily tuned.
