A new photoinitiating system for the metal-free preparation of conjugated microporous polymers (CMPs) is reported. In this approach, irradiation of solutions containing an electroactive monomer, possessing both carbazole and fluorene units, 9,9′-(9,9-dihexyl-9H-fluorene-2,7-diyl)bis-9H-carbazole (CFD), and the iodonium salt (Ph2I+PF6–) as the oxidizing agent resulted in the formation of CMPs. Photoinduced step-growth polymerization proceeded through the successive electron transfer between the excited CFD and iodonium salt, proton release, and coupling reactions. The polymers formed were characterized by FT-IR and 1H NMR analyses. The electrochemical and optical properties of CMPs before and after the dedoping process were evaluated by cyclic voltammetry, differential pulse voltammetry, and UV–vis absorption and photoluminescence techniques. The porous structure of the obtained polymers was confirmed by atomic force microscopy and scanning electron microscopy studies.

芴-咔唑基多孔聚合物的光诱导电子转移反应
报道了一种用于无金属制备共轭微孔聚合物（CMP）的新型光引发体系。在这种方法中，辐照含有具有咔唑和芴单元，9,9'-（9,9-二己基-9 H-芴-2,7-二基）bis-9 H-咔唑的电活性单体的溶液（CFD ），并用碘盐（Ph 2 I + PF 6 –）作为氧化剂，导致了CMP的形成。光诱导的逐步增长聚合反应是通过激发的CFD和碘鎓盐之间的连续电子转移，质子释放和偶联反应进行的。形成的聚合物通过FT-IR和11 H NMR分析。通过循环伏安法，差分脉冲伏安法以及UV-vis吸收和光致发光技术对去掺杂工艺前后的CMP的电化学和光学性质进行了评估。通过原子力显微镜和扫描电子显微镜研究证实了所获得的聚合物的多孔结构。
