Callari, Fiorella L.,Sortino, Salvatore
supporting information; experimental part, p. 6179 - 6181 (2009/05/06)
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.

Catch-and-release of porphyrins by photoswitchable self-assembled monolayers

, p. 4184 - 4188 (2008/12/21)
A novel cationic, photoresponsive azobenzene derivative with the characteristic of self-assembly, 2-{4-[(E)-(4-{[11-(dodecylthio)undecyl]oxy} phenyl)diazenyl]phenoxy}-N,N,N-trimethylethanaminium bromide (1), has been synthesized. Self-assembled monolayers (SAMs) of 1 on ultrathin, transparent platinum electrodes have been fabricated and the reversible trans cis interconversion has been demonstrated by absorption spectroscopy in transmission mode and contact angle measurements. It is shown that such photoresponsive SAMs promote the binding of anionic porphyrins at the metal surface and trigger their release upon light excitation exploiting the different light-controlled electrostatic interactions with the two isomeric forms of 1.

The shuttling process of α-CyD in three rotaxanes (1-3) containing α-cyclodextrin (α-CyD) as a ring, azobenzene as a photoactive group, viologen as an energy barrier for slipping of the ring, and 2,4-dinitrobenzene as a stopper was investigated. The trans
