Description
Summary:Photoinduced electron transfer in a self-assembled supramolecular ladder structure comprising oligomeric porphyrin rails and ligated dipyridyltetrazine rungs was characterized by transient absorption spectroscopy and transient direct current photoconductivity to be mainly from an oligomer (rail) to the center of a terminal tetrazine (rung), with the remaining hole being delocalized on the oligomer and subsequent charge recombination in 0.19 ns. Photoinduced electron transfer in a self-assembled triporphyrin ladder ligated by three dipyridyltetrazines was characterized by transient dc photoconductivity to be from the triporphyrin (rail) to the center of the terminal dipyridyltetrazine (rung).
