applications. The scope for further fine‐tuning of these optical properties based on additional structural modifications, such as the incorporation of fused benzene rings to form ABAB structures by using a thiophene precursor with a fused bicyclo[2.2.2]octadiene ring and the introduction of various substituents onto the meso‐phenyl rings, is also examined.
据报道,合成了一系列新型的核心修饰和稠合环膨胀的
四苯基卟啉。使用理论计算,磁圆二向色性(MCD)和荧光光谱测量来分析用16族氧,
硫,
硒和
碲原子进行的核修饰对
卟啉的光学性质和电子结构的影响。观察到Q和B谱带明显的红移和加速的系统间交叉速率,因此使这些化合物潜在地适合于各种应用。基于其他结构修饰,例如通过使用
噻吩前体与稠合双环[2.2]并入稠合苯环以形成ABAB结构,可以进一步微调这些光学性质。还研究了内消旋-苯环。
