Model Substances for Electro-optical and Dielectric Studies, Part I Synthesis and Structure of 1,4-Bis(4'-dimethylamino-3',5'-dicyanophenyl)bicyclo[2.2.2]octane

Abstract

A synthesis for a new 1,2,6-donor-acceptor-substituted chromophoric benzene system is given. This chromophore is incorporated in a bicyclo[2.2.2]octane system to build up model compounds for electro-optical and dielectrical studies. Furthermore a preparative convenient route to derivatives of 1,4-bis(diphenyl)bicyclo[2.2.2]octane is worked out. The structures of the new compounds are proven by spectroscopical means.
