Subphthalocyanines: Supramolecular Organization and Self-Assembling Properties
To enhance the understanding of the nature of these curve pi-extended surfaces, we have undertaken a series of studies, including the synthesis and characterization of subphthalocyanine-based capsules. These supramolecular systems have been successfully been employed for the encapsulation of fullerenes. Furthermore, it was possible to evaluate the binding constants of the host-guest complexes. Finally, a full study of the photophysical properties revealed that the subphthalocyanines can undergo an energy transfer transduction of singlet excited state energy to the fullerene inside the cavity upon photoexcitation.
SubPc pi-systems can be organized at supramolecular level. Thus, the self-assembly of axial dipolar subphthalocyanine molecules in the presence of electric fields leads to uniaxially oriented columnar liquid crystalline materials that exhibit permanent polarization.
