Chemical synthesis and material study of regioregular P3HS. a Grignard metathesis route to regioregular P3HS. b Solution and thin film UV‒vis absorption spectra of P3HT and P3HS showing distinct redshifts and increasing vibronic character (due to chain ordering) upon film formation. c Thin film CV of P3HT and P3HS. d Transfer (left) and output (right) characteristics of P3HS OFET devices; saturated carrier mobility of 0.02–0.04 cm2 V−1 s−1. Vg = gate voltage, Isd = source-drain current, Vsd = source-drain bias voltage. Reproduced from ref. [24] with permission from the Royal Society of Chemistry
