The synthesis and formulation of organic semiconductors for the emerging technology of organic electronics requires the use of preparative methods and solvents being environment friendly. Today most of the active layer materials for the organic photovoltaic devices and modules are using chlorinated solvents, which are toxic and hazardous. In this work, the synthesis of poly[N-9'-heptadecanyl-2,7-carbazole-alt-5,5-(4,7-di-2-thienyl-2',1',3'-benzothiadiazole] (PCDTBT) in propan-1-ol is presented as the dispersant continuous phase in the presence of poly(vinylpyrrolidone) used as stabilizer. Suzuki-Miyaura polycondensation of 9-(9-heptadecanyl)-9H-carbazole-2,7-diboronic acid bis(pinacol) ester and 4,7-bis(2-bromo-5-thienyl)-2,1,3-benzothiadiazole in alcohol dispersion yields colloidally stable nanoparticles of PCDTBT with particles size of 330-1300 nm, depending on the stabilizer concentration. Other reaction parameters are also discussed such as the amount of base or Pd catalyst.
用于有机电子新兴技术的有机半导体的合成与配方需要使用环境友好的制备方法和溶剂。如今，大多数有机光伏器件和模块的活性层材料都使用氯化溶剂，这些溶剂有毒且有害。在这项工作中，介绍了在用作稳定剂的聚乙烯吡咯烷酮存在下，以丙醇为分散剂连续相合成聚[N-9'-十七烷基-2,7-咔唑-alt-5,5-(4,7-二-2-噻吩基-2',1',3'-苯并噻二唑]（PCDTBT）的方法。9-(9-十七烷基)-9H-咔唑-2,7-二硼酸双(频哪醇)酯与4,7-双(2-溴-5-噻吩基)-2,1,3-苯并噻二唑在醇分散体系中的铃木-宫浦缩聚反应生成了粒径为330-1300 nm的PCDTBT胶体稳定纳米颗粒，其粒径取决于稳定剂浓度。还讨论了其他反应参数，如碱或钯催化剂的用量。
