Abstract

A pyridyl side arm porphyrin incorporating C10 alkyl chains at the periphery of the porphyrin suitable for surface immobilisation on HOPG has been synthesised and tested for two state switching in solution. Temperature switching, involving reversible complexation of a covalently appended pyridyl side arm to the Zn(II) porphyrin, was comprehensively characterised by using variable temperature 1H NMR (-30 to +100∘C) and UV-vis (10 to 90∘C) in toluene. Molecular modelling assisted in understanding strain within the complex.
