Progress in the molecular design and processing protocols of semiconducting polymers has opened significant opportunities for the fabrication of low-cost plastic electronic devices. Recent studies indicate that field-effect transistors and organic solar cells fabricated using narrow-bandgap regioregular polymers with translational symmetries in the direction of the backbone vector often outperform those containing analogous regiorandom polymers. This review addresses the cutting edge of regioregularity chemistry, in particular how to control the spatial distribution in the molecular structures and how this order translates to more ordered bulk morphologies. The effect of regioregularity on charge transport and photovoltaic properties is also outlined.

高分子的分子设计和加工工艺的进展为低成本塑料电子器件的制造开辟了广阔的前景。最近的研究表明，使用具有沿主链向量平移对称性的窄带隙规整形聚合物制备的场效应晶体管和有机太阳能电池往往优于含有类似规乱形聚合物的器件。本综述讨论了规整形化学的前沿，特别是如何控制分子结构中的空间分布，以及这种有序性如何转化为更有序的体相形态。还概述了规整形对电荷输运和光伏性能的影响。
