Abstract: A stimulus-responsive molecule 1 was designed and prepared to control
ligand-binding ability of multiple receptor sites, two zinc tetraphenylporphyrin (ZnTPP) andone zinc diethynyldiphenylporphyrin (ZnDEDPP), by effector molecule 2. Spectroscopic
titrations indicated that stable supramolecular complex 1•2 (K = 6.7 × 106 M-1) was produced
via the cooperative formation of multiple hydrogen bonds and coordination bonds. As theresult, the binding of a ligand to ZnTPP was competitively inhibited by 2. In addition, theformation of 1•2 brought about conformational change of the side arms to cover both faces ofZnDEDPP with shielding panels (HAB). As a result, the binding constant of ZnDEDPP in 1•2
with 4-phenylpyridine was decreased to 8.9% of that in 1. Namely, the ligand-binding abilityof ZnDEDPP was suppressed by allosteric mechanism. The effector molecule can reduce
ligand-binding ability of both ZnTPP and ZnDEDPP in 1 by competitive and allostericmechanism, respectively. The catalytic activity of N-methylpyrrolidine in Michael addition
was successfully regulated by 1. We will present molecular design and the allosteric effect indetail.
