Conformation-dependent hydrogen evolution with cobalt(II)tetraphenylporphyrin solubilized into poly(l-glutamate)-decylammonium ion complex

Visible light irradiation of a system consisting of cobalt(II)tetraphenylporphyrin, methylviologen, ethylenediaminetetraacetic acid disodium salt and Pt-loaded poly(l-glutamate) (Poly(Glu)) in aqueous decylammonium chloride (DeAC) solution, resulted in hydrogen production. The rate of hydrogen evolution depended on the change in the conformation of Poly(Glu) induced by the cooperative binding with DeAC.
