Directly linked hydroporphyrin dimers

Chem Commun (Camb). 2016 Jul 12;52(58):9056-8. doi: 10.1039/c6cc00516k.

Abstract

Directly linked hydroporphyrin (chlorin) dimers were accessed regioselectively from bromochlorins. Versatile 15-borylated chlorins were prepared in excellent yield via Miyaura borylation. Suzuki coupling yielded meso-meso-linked homo- and heterodimers, and meso-β-linked dimers. The photophysical and electrochemical properties of the dimers are reported.
