| Abstract: | Polycarbazoles (PCZ) are well-studied class of polymers with good electrical and photoactive properties. Here, we have prepared the well-defined 3,6-PCZ with a molecular weight of 6148 and low polydispersities of 1.18. We also used 2,7-dibromo-9-(heptadecan-9-yl)-9H-carbazole as monomer to increase the solubility of the polymer. The 2,7-PCZ with a high molecular weight over 10,000 and low polydispersity of 1.27 was prepared successfully. |
