-BODIPY conjugate. The meso-iodophenyl functionalized di-p-benzihomoporphyrin was coupled with ethynyl-functionalized BODIPY under mild Pd(0) coupling condition to synthesize diphenylethyne-bridged di-p-benzihomoporphyrin-BODIPY conjugate. The two conjugates were characterized by HR-MS, NMR, absorption, electrochemical, fluorescence and DFT studies. The spectral and electrochemical studies indicated
两个单声道中观-功能化[20]二-p-苯并同卟啉含有p-甲酰基苯基和p-碘苯基在中观通过将一当量的适当四吡喃与一当量的p-甲酰基苯甲醛/p在温和的酸催化条件下,在 CH 2 Cl 2中的碘苯甲醛。这中观-甲酰基苯基和中观-碘苯基官能化二-p-苯并同卟啉用于合成两个共价连接的二-p-苯并同卟啉-BODIPY 偶联物。这中观-甲酰基苯基官能化二-p-苯并同卟啉转化为相应的中观-二吡咯基取代的二-p-苯并高卟啉通过在酸催化条件下用过量的吡咯处理。在下一步中,中观-二吡咯二-p-苯并高卟啉经过氧化,然后是BF 2络合,得到直接连接的二-p-苯并同卟啉-BODIPY 偶联物。这中观-碘苯基官能化二-p-苯并高卟啉在温和的Pd(0)偶联条件下与乙炔基官能化BODIPY偶联合成二苯乙炔桥联二-p-苯并同卟啉-BODIPY 偶联物。通过 HR-MS、NMR、吸收、电化学、荧光和 DFT 研究对这两种偶联物
