    • Absorption spectroscopy does not allow clear observation of the changes in the Soret absorption spectral profile due to the overlap with the absorption of the azobenzene chromophore. In contrast, fluorescence excitation spectra allow the clear observation of the spectral changes of the TPPS without the interference of the azo-chromophore due to fact that the azobenzene does not show any luminescence. The absorption changes observed in the Q-band region (data not shown) reproduced well those noted in the excitation spectra in the same spectral region.

    • -1 was estimated through the fluorescence spectral changes We cannot rule out that π-π stacking interaction between the aromatic rings of the 1-trans can probably play a key role in the stabilization of the H-aggregates. Such type of interactions are expected to be disfavored in the 1-cis due to its non-flat structure, accounting for the weak affinity of this isomer for TPPS
