Abstract
AbstractPolymers with open‐shell π‐conjugated structure and thiophene‐based building blocks are designed for electropolymerization. These systems are expected to electropolymerize and form solution‐processable conjugated microporous polymer films, which can be used for device fabrications. The designed radical structure has a low highest occupied molecular orbital (HOMO)–lowest unoccupied molecular orbital (LUMO) gap, high electronic hopping rate for the hole transfer and electron transfer, and ultimately high conductivity. The eclipsed dimer has higher conductivities than that of staggered dimer. The designed monomer with substituted groups has lower conductivities due to steric effect. The open‐shell systems designed will be promising materials with various applications. Design principles for open‐shell organic materials can be established based on the trends of this paper.
