摘要：

Another dimension: Two newly designed two-dimensional (2D) conjugated polymers, PBDTTT-E-T (see scheme; left) and PBDTTT-C-T, were prepared and their properties compared to those of the alkoxy-substituted analogues (right). PBDTTT-E-T and PBDTTT-C-T exhibited smaller band gaps, lower-energy HOMO levels, better thermal stabilities, and much better photovoltaic properties. Therefore, the 2D structures are feasible for the design of photovoltaic polymers. Copyright © 2011 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
