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,
