A chiral cyclotrisazobiphenyl macrocycle was synthesized conveniently in three steps from the literature known 3,3′-diaminobimesityl in 37–38% overall yield. Irradiation with 302 nm, 365 nm or visible light allows access to different photostationary states (PSSs). These PSSs can be conveniently read out by CD-spectroscopy as each of them exhibits a positive, a negative, or no signal, respectively,
从已知的文献3,3'-diaminobimesityl的三个步骤中,方便地合成了一个手性的环三氮杂联苯大环化合物,总产率为37-38%。用302 nm,365 nm或可见光照射可以访问不同的光平稳状态(PSS)。这些PSS可以通过CD光谱方便地读出,因为它们各自在275 nm处分别显示正信号,负信号或无信号。
