Photoisomerization of azobenzenes is an active area of research since it may play an important role in light‐driven molecular systems. Here is described the first example of a chiral azobenzene system where the Z ‐isomer (see Figure) has greater helical twisting power than the corresponding E ‐isomer. This is the opposite of what occurs with conventional chiral azobenzenes, which holds significance for the molecular design of optical devices.
