Redox-Induced cis → trans Isomerisation of Bis(porphyrinyl)ethenes: A Possible Basis for a Molecular Memory Element?

Redox-Induced cis → trans Isomerisation of Bis(porphyrinyl)ethenes: A Possible Basis for a Molecular Memory Element?

trans-1,2-Bis(octaethylporphyrin-5-yl)ethene free base and its dinickel(II) complex exhibit narrow electrochemical band gaps (1.44 and 1.49 eV, respectively) and broad, solvent-dependent absorption bands at low energy, whilst the corresponding cis isomers undergo rapid redox-induced cis → trans isom...
