In the current state of organic semiconductor development, n-type semiconductors are significantly less advanced than their p-type counterparts, particularly in realm high-electron-mobility materials, which crucial for high-grade field-effect transistors (OFETs) commercial electronics. Over past few years, incorporation B←N coordination units has emerged as a promising approach to enhancing properties. However, exploration polymers with π-conjugated extensions different directions been largely overlooked. This study introduces two novel coordinated BDP-based polymers, P1 and P2, synthesized distinct extension directions: along backbone perpendicular it, respectively. P1, its advantages energy levels, planarity, crystallinity, transport, demonstrates an electron mobility 1.81 cm2 V–1 s–1, is more twice performance P2. achievement sets new benchmark OFETs, marking one highest reported mobilities date.
