Abstract:
Multiporphyrin arrays are a complex class of molecules with numerous potential applications in
energy transfer, photomedicine and light harvesting. We have developed a facile/versatile route
to a class of triptycene linked porphyrin arrays via both Suzuki and Sonogashira cross coupling
methods which makes use of the rigid three-pronged orientation of triptycene to construct
trimeric porphyrin arrays linked either in the meso or ?-position with various linker groups. In
order to understand the properties of these potential antenna systems and probe their potential
applications, the coordination behavior of zinc(II) derivatives with mono- and bidentate N-donor
ligands was investigated. Depending on ligand concentration, both one- and two-point binding
was observed with a bidentate ligand. Also/In addition, different cavity sizes, obtained by the
use of different linker groups, resulted in differences in the binding properties of each trimeric
system.
