Structural defects in conjugated copolymers are severely detrimental to the optoelectronic properties and the performance of the resulting electronic devices fabricated from them. Therefore, the much-desired precision synthesis of conjugated copolymers with highly regular repeat units is important, but presents a significant challenge to synthetic materials chemists. To this end, aryl sulfides are naturally abundant substances and offer unrealized potential in cross-coupling reactions. Here we report an efficient room temperature polycondensation protocol which implements aryl disulfide C-S activation to produce defect-minimized semiconducting conjugated copolymers with broad scope and applicability. Thus, a broad series of arylstannanes and thioethers are employed via the present protocol to afford copolymers with number-average mol. weights (Mns) of 10.0-45.0 kDa. MALDI and NMR anal. of selected copolymers reveals minimal structural defects. Moreover, the polymer trap d. here is smaller and the field effect mobility higher than that in the analogous polymer synthesized through thermal-activation Stille coupling.
