Abstract

Porphyrins substituted with, for example, vinyl and acetylene groups are provided, along with polymers containing the same. In preferred embodiments, the substituted porphyrins are prepared by coupling halogenated porphyrins with carbon-centered anionic groups via metal-mediated crosscoupling reactions under stoichiometric or catalytic conditions.
