title: Synthesis of extended π-systems through C-H activation.
abstract: Activation of aromatic CH bonds by a transition metal catalyst has received significant attention in the synthetic chemistry community. In recent years, rapid and site-selective extension of π-electron systems by C-H activation has emerged as an ideal methodology for preparing organic materials with extended π-systems. This Review focuses on recently reported π-extending C-H activation reactions directed toward new optoelectronic conjugated materials.
