Abstract

To the best of our knowledge, this study reports the first direct electropolymerization of a dicyanobenzene-carbazole dye functionalized with an imidazole group to prepare redox- and photoactive porous organic polymer (POP) films in controlled amounts. The POP films were grown on indium-doped tin oxide (ITO) and carbon surfaces using a new monomer, 1-imidazole-2,4,6-tri(carbazol-9-yl)-3,5-dicyanobenzene (, 3CzImIPN), through a simple one-step process. The structure and activities of the POP films were investigated as photoelectrodes for electrooxidations, as heterogeneous photocatalysts for photosynthetic olefin isomerizations, and for solid-state photoluminescence behavior tunable by lithium-ion concentrations in solution. The results demonstrate that the photoredox-POPs can be used as efficient photocatalysts, and they have potential applications in sensing.

摘要

据我们所知，本研究首次报道了一种用咪唑基团功能化的二氰基苯 - 咔唑染料的直接电聚合，以制备可控量的氧化还原和光活性多孔有机聚合物（POP）薄膜。使用新型单体1 - 咪唑 - 2,4,6 - 三（咔唑 - 9 - 基）- 3,5 - 二氰基苯（3CzImIPN），通过简单的一步法在铟掺杂氧化锡（ITO）和碳表面生长POP薄膜。研究了POP薄膜作为电氧化光电极、光合烯烃异构化的多相光催化剂以及溶液中锂离子浓度可调节的固态光致发光行为的结构和活性。结果表明，光氧化还原 - POPs可用作高效光催化剂，并且在传感方面具有潜在应用。
