一种meso‑位乙炔基桥联的D‑π‑A型BODIPY类染料及其制备方法
摘要：
本发明公开了一种meso‑位乙炔基桥联的D‑π‑A型BODIPY类染料及其制备方法。该类染料是通过先在芴、苯并二噻吩、吩噻嗪等基团上引入乙炔基，然后再与合成的meso‑位Cl取代的BODIPY单元通过Sonogashira偶联反应得到meso‑位乙炔基桥联的D‑π‑A型BODIPY类染料I。该类染料的合成方法简单，反应条件易于控制，产率较高，具有普遍适用性，可以高效合成；并可被广泛应用于能源、生命、分析、材料等科学领域，尤其适合作为有机小分子太阳能电池给体材料。
摘要（英）：

The invention discloses meso-ethynyl bridged D-Pi-A type BODIPY dye and a preparation method thereof. According to the dye, ethynyl is introduced on groups such as fluorene, benzene thiophene and phenthazine at first, and then the groups and a synthesized meso-cl substituted BODIPY unit are subjected to coupled reaction through Sonogashira to obtain the meso-ethynyl bridged D-Pi-A type BODIPY dye I. The synthesis method of the dye is simple, reaction conditions are easily controlled, yield is high, universal applicability is high, the meso-ethynyl bridged D-Pi-A type BODIPY dye can be synthesized efficiently; and the meso-ethynyl bridged D-Pi-A type BODIPY dye can be widely applied to scientific fields of energy, life, analysis, materials and the like, and is particularly suitable for being used as an organic small molecule solar battery donor material.
