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. The continued search of high-performance semiconductors for organic electronics calls for smart molecular designs. Here, Yinget al. review the recent development of synthesizing regioregular narrow bandgap conjugated polymers and the effect of regioregularity on transistor and photovoltaic performance.
