Mono and bis ethynyl and ethynylphenyl beta-substituted porphyrins have been synthesized and characterized. Their conformational properties have been analyzed through a combination of NMR experiments and molecular mechanic calculations, while UV-Vis absorption and fluorescence measurements together with electrochemical studies allows us to probe the existence of intramolecular electronic processes.

Abstract
Mono and bis ethynyl and ethynylphenyl beta-substituted porphyrins have been synthesized and characterized. Their conformational properties have been analyzed through a combination of NMR experiments and molecular mechanic calculations, while UV-Vis absorption and fluorescence measurements together with electrochemical studies allows us to probe the existence of intramolecular electronic processes. The role of the beta-substituents and of the spacer is underlined.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
