Charge transport in semiconducting conjugated polymers mainly devolves on the solid-state ordering of polymer chains with respect to its packing and orientation. Therefore, controlling the inter- and intra-mol. interactions of polymer chains is vital for achieving high performance conjugated polymers for electronic applications. Herein, by a macromol. design scheme, we optimized the microstructure of a regiorandom poly (thiophene) copolymer for efficient charge transport. By introducing side chain-free Ph and pyridyl units into the backbone, we achieved regiorandom polymers possessing improved inter- and intra-mol. interactions with a much closer π-π mol. stacking and a larger size of crystallites. Improved charge carrier motion and transport in both vertical and horizontal directions were revealed when the resulting Ph and pyridyl substituted polymers were applied as hole-transporting materials in organic field-effect transistors, diode-like space-charge-limited current devices, and perovskite solar cells. Particularly, the pyridyl substituted polymer exhibited more than two times higher charge carrier mobilities in the above mentioned device configurations compared with the pristine regiorandom poly (thiophene). In addition to this study using 2,5-Dibromopyridine, there are many other studies that have used 2,5-Dibromopyridine(cas: 624-28-2Reference of 2,5-Dibromopyridine) was used in this study.
2,5-Dibromopyridine(cas: 624-28-2) belongs to pyridine. Pyridine and pyridine-derived structures are privileged pharmacophores in medicinal chemistry and an essential functionality for organic chemists. As the prototypical π-deficient heterocycle, pyridine illustrates distinctive chemistry as both substrate and reagent. Reference of 2,5-Dibromopyridine
