Patterning of organic semiconductors(OSCs) is vital for realization of high-performance electronics. To this end, direct patterning methods using crosslinkers have numerously been emerged. Among them, azide(-N3) crosslinkers have representatively been developed; however, they require high energy (>140°C or 254nm UV) to be activated, and extremely low loading amounts to prevent degradation of electrical property of OSCs. Here, we demonstrate a low-energy patternable polymer semiconductor network(LE-PSN) based on carbene-based crosslinkers with tetrahedral diazo(=N2) moieties. Due to low activation energy of the carbene, LE-PSN can achieve high crosslinking efficiency and high-resolution patterns through a low-energy processes(100°C or 365 nm UV). In addition, the electrical performance of LE-PSN showed non-destructive regardless of high loading amount of the crosslinkers(>10wt%). We believe that LP-PSN will provide a guidance for the next generation of OSC patterning technologies.
