Abstract

Abstract : A series of Donor–Accepting–Donor (D–A–D) and Accepting–Donor–Accepting (A–D–A) compounds have been prepared and employed in the synthesis of oligomers potentially useful in optoelectronic applications. Abstract : A series of Donor–Acceptor–Donor (D–A–D) and Acceptor–Donor–Acceptor (A–D–A) compounds have been prepared exploiting the relative ability of polyfluorinated azobenzenes and benzophenone to undergo aromatic nucleophilic substitution reactions with aromatic amines. A high para -regioselectivity is obtained when fluorene and carbazole-based diamines have been used in a high Donor Number solvent environment such as DMSO. The prepared triads have been employed in the synthesis of oligomers with the aim of evaluating them as photovoltaic material additives in optoelectronic applications.
