Synthesis of two dihydropyrroloindoledione-based copolymers for organic electronics
Two novel dihydropyrroloindoledione (DPID)-based copolymers have been synthesized in a two directional approach and characterized (gel permeation chromatography (GPC), ultraviolet-visible (UVvis), cyclic voltammetry, and computational models). These planar, broad absorption copolymers show promise for use in organic electronics, with deep energy levels and low bandgaps. The two-directional Knoevenagel condensation used demonstrates the versatility of DPID as a useful yet underexploited conjugated unit. (c) 2012 Wiley Periodicals, Inc.
