(MATerry), 1,6‐diazaterrylene (DiATerry) and pristine terrylene (Terry), were synthesized by changing the number of nitrogen atoms at the bay region (1 and 6 positions of the Terry core). The electrochemical measurements suggested that the first one‐electron reduction and oxidation potentials became positively shifted with increasing numbers of nitrogen atoms. This agreed with the energies of the corresponding

化学测量表明,随着氮原子数量的增加,第一个电子还原和氧化电势正移。这与通过DFT方法估算的相应最高占据分子轨道(HOMO)和最低未占据分子轨道(LUMO)状态的能量一致。相反,HOMO-LUMO间隙大致保持恒定。这种趋势与通过吸收光谱和荧光光谱观察到的光谱行为非常相似。DiATerry的溶剂极性相关光谱趋势表明了分子内电荷转移(ICT)特性。对各种溶剂中激发态动力学的评估表明,通过ICT激发态相对于基态的电子构型变化。Lippert-MAtaga图支持了这一点。最后,还观察到了可逆的质子化和去质子化过程。
