Herein, we report a series of tetrafluoroethylene (TFE)-containing semiconducting polymers PNBDO-FDTEm (m = 90, 80, 70, 60, and 0), in which the TFE segments were first introduced into polymeric main chains as flexible π-nonconjugated nodes, and its fully conjugated analog PNBDO-FDTE100. Our results indicate that the TFE segment is quite compatible with the NBDO-alt-FDTE conjugated matrix system. The HOMO/LUMO energy levels (approx. -6.0/-4.0 eV) and optical band gaps (1.28 eV) remain almost the same in the polymers with the TFE content varying from 0% to 40%. The polymers PNBDO-FDTEm (m = 90, 80, 70, and 60) have similar highly ordered mol. packing with close π-π stacking in a thin film as PNBDO-FDTE100 does, implying that the TFE segments exert no clear neg. influences on the mol. packing of these polymers either. PNBDO-FDTE100 exhibited a much high electron mobility (μe) of 7.43 cm2 V-1 s-1, while PNBDO-FDTE90 and PNBDO-FDTE80 also showed impressively high μe values of 7.25 and 6.00 cm2 V-1 s-1, resp. However, PNBDO-FDTEm (m = 70, 60, and 0) afforded a μe as low as 0.182 cm2 V-1 s-1. We attributed this to the transition of the carrier transport mode caused by the increase in the number of π-nonconjugated nodes. The experimental process involved the reaction of Tris(dibenzylideneacetone)dipalladium(0)(cas: 51364-51-3Product Details of 51364-51-3)
Tris(dibenzylideneacetone)dipalladium(0)(cas: 51364-51-3) is used in the preparation of semiconducting polymers processed from nonchlorinated solvents into high performance thin film transistors.Product Details of 51364-51-3It is used as catalyst for the synthesis of epoxides, alpha-arylation of ketones, in combination with BINAP for the asymmetric heck arylation of olefins, site-selective benzylic sp3 palladium-catalyzed direct arylation and homoallylic diamination of terminal olefins.
