The synthesis of a naphthalene diimide bithiophene copolymer P(EO-NDIT2) with branched, base-stable, and purely ether-based side chains is presented. Stille polycondensation leads to high molecular weights that are limited by methyl transfer and eventually T2 homocouplings. While extensive solution aggregation hampers molecular weight determination by conventional methods, NMR spectroscopy allows identification of both T2-(H and methyl) and NDI-related (methyl) end groups, enabling thedoi:10.1021/acs.macromol.0c00657.s001 fatcat:cyxpjz3r6rbw3kopwvetagqpna
