Formation and Molecular-Structures of meso-1,2-Bis(9-anthryl)-1,2-diacetoxyethanes

Abstract

The molecular structures of meso-1,2-diacetoxy-1,2-di(9-anthryl)ethane (1) and meso-1,2-diacetoxy-1,2-di(10-acetoxy-9-anthryl)ethane (2) have been established by X-ray diffraction. Their molecular conformations are characterized by a staggered arrangement of substituents about the central ethane linkage, and anti-orientation of the anthracene moieties. The dianthrylethane derivative (1) was isolated in two crystalline modifications, (1a) and (1b), whose different crystal luminescence properties are correlated with the differences in packing pattern.
