title: Controlling molecular assembling by photons: reversible light-powered monomer-aggregate interconversion of porphyrins.
abstract: Reversible formation and destruction of H-type aggregates of an anionic porphyrin can be controlled exclusively through light inputs of different energy exploiting the different interactions with the two isomeric forms of a cationic photoresponsive azobenzene-based surfactant.
