一种吩噻嗪基D-A-π-A型有机染料的制备方法
摘要：
本发明公开了一种吩噻嗪基D‑A‑π‑A型有机染料的制备方法。主要采用二苯胺、吩噻嗪作为给电子单元，苯并噻二唑作为辅A单元，噻吩作为共轭桥连π单元，氰基丙烯酸作为吸电子A单元；通过C‑N偶联、NBS上溴、铃木偶联等合成方法制备D‑A‑π‑A型有机染料分子。本发明工艺简单，制得的吩噻嗪基D‑A‑π‑A型有机染料，其结构能有效拓宽染料吸收光谱，提高电子注入效率和能量转换效率，将其应用到染料敏化太阳能电池中可有效提高光电转化效率。
摘要（英）：

The invention discloses a preparation method of a phenothiazine-based D-A-Pi-A type organic dye. The preparation method comprises the following steps that: diphenylamine and phenothiazine are mainly used as an electron donor, diazosulfide is used as a co-A unit, thiophene is used as a conjugate bridging Pi unit, and cyanoacrylic acid is used as an electron absorption A unit; D-A-Pi-A type organicdye molecules are prepared through synthesis methods of C-N coupling, NBS (N-bromosuccinimide) feeding, Suzuki-Miyaura coupling and the like. The process of the preparation method is simple; the structure of the prepared phenothiazine-based D-A-Pi-A type organic dye can effectively expand the dye absorption spectrum and improve the electron injection efficiency and energy conversion efficiency; when the phenothiazine-based D-A-Pi-A type organic dye is applied to a dye sensitization solar battery, the photoelectric conversion efficiency can be effectively improved.
