The organic glass-forming materials 1, 3-bis (1-naphthyl)-5-(2-naphthyl) benzene (2) and its partially deuterated analogue, 1, 3-bis (1-naphthyl-d 7)-5-(2-naphthyl) benzene (2-d 14), have been synthesized on a gram scale using Suzuki coupling reactions. Detailed spectroscopic studies afford complete NMR assignments (1H, 2H, 13C) for both compounds. Modest energy barriers for the interconversion of atropisomers (ca. 15 kcal/mol) result in a ...
