Oligo(para-phenylene)s (DAOPPs) 2a -2d (n ¼ 1 -4) with terminal donor -acceptor substitution (D ¼ C 6 H 13 O, A ¼ NO 2 ) were prepared by applying Suzuki cross-couplings for chain extension and end capping. The push -pull effect induces short-reaching polarizations of the chain consisting of conjuga
