We prepared two heterooligomeric arrays based on free base/metalloporphyrins at axial positions and a metalloid phthalocyanine as a basal scaffolding unit by using the axial-bonding capabilities as well as the known oxophilicity of dihydroxytin(IV) phthalocyanine. Both heterotrimers were completely characterized by elemental analysis, MALDI-TOF MS, and 1H NMR (one- and two-dimensional), UV/Vis, and fluorescence spectroscopy as well as cyclic voltammetry. The ground-state properties indicate that there is minimal pi-pi interaction between the macrocyclic units. The excited-state properties show that there is electronic energy transfer competing with photoinduced electron transfer from the singlet state of the axial porphyrin to the central metalloid phthalocyanine and a photoinduced electron transfer from the ground state of the axial porphyrin to the singlet state of the central metalloid phthalocyanine.

Synthesis and Photophysical Studies of New Porphyrin–Phthalocyanine Dyads with Hindered Rotation

A series of novel porphyrin-phthalocyanine (Por-Pc) dyads 1-3 have been synthesized by using standard methodologies for unsymmetrically substituted phthalocyanine preparation. These two chromophoric units have been directly linked for the first time, that is, without any spacer, through the β-pyrrolic position of a meso-tetraphenylporphyrin, thus allowing a close proximity of the two units in a rigid arrangement. For this, a novel porphyrin-phthalonitrile precursor 4 had to be prepared. The UV/Vis spectra indicate that the basic electronic characteristics of both individual units (i. e., porphyrin and phthalocyanine) are retained in the hybrid Por-Pc mole-
