✦ Synopsis
A&l-act. Two isomers of Z,Z-9,10-bis(styryl)anthracene have been observed by 1H and 1% NMR spectroscopy. The t3C chemical shifts were assigned by the 1%tH HETCOR technique. The barrier to interconversion of these two isomers is measured to 18 kcal/mol. The syvn isomer forms a charge transfer complex with trinitrobenzene (TNB) as determined by 1 H NMR methods
