Abstract:
As part of a strategy to explore highly functionalized macromolecular semiconductors, a series of highly substituted twelve‐armed macromolecules F1CzTr‐F3CzTr consisting of truxene, 9‐phenylcarbazole and oligofluorene units were synthesized. To accomplish the synthesis of twelve‐armed targets, a high yield microwave enhanced synthesis method for direct twelve‐fold Suzuki couplings was developed. The resulting materials exhibited high purity and good monodispersity (PDI 1.01–1.03). The molecular weight of the compound F3CzTr achieved 14 266 g · mol?1, representing one of the largest well‐defined starburst conjugated molecules. The thermal, photophysical and electrochemical properties were investigated.
