Abstract

A family of chiral molecular squares based on fac-Re(CO)₃Cl metallocorners and enantiopure atropisomeric bipyridine bridging ligands (L_1-4) have been synthesized in high yields by refluxing ClRe(CO)₅ and L_1-4 in 1:1 molar ratio. These novel chiral metallocycles have been characterized by ¹H and ¹³C{1H} NMR, UV-vis, luminescence, and circular dichroism (CD) spectroscopies, FAB mass spectrometry, and microanalysis. Molecular square 4 which contains four 1,1′-bi-2-naphthol functionalities exhibits interesting enantioselective luminescence quenching by 2-amino-1-propanol. This research illustrates the potential of generating novel functional materials based on supramolecular chemistry.
