Abstract
The Suzuki–Miyaura coupling reaction of pyren-2-yl boronic acid ester with a meso-dibromodiphenylporphyrin derivative was carried out to give another pyrene-substituted porphyrin. The electrophilic substitution reaction occurred selectively on the porphyrin nucleus of this molecule. The introduced pyrenes acted as a light-harvesting antenna.

Because pyrene is larger than benzene, the space of the lattice produced by 3(M) and/or 7 should be larger than that produced by TPP. For example, the crystal of 7 incorporated two toluene molecules in its unit cell.12 The incorporation of solvent molecules could be one of the reasons for the inaccurate EA values. The characterization of new products was based on high-resolution mass spectroscopic analysis

- 12 Preliminary single-crystal diffraction study of 7 was carried out (see Figure 2). However, the marked disorder of solvent molecules prevented the complete analysis.

- 15 Similar experiments were carried out in polar solvent DMF and similar results were obtained; that is, energy transfer occurred from pyrenes to porphyrin.
- 16 One of the objectives of this study was to synthesize pyrene-fused porphyrins. Attempts to obtain such porphyrins under oxidative conditions, such as FeCl3 in MeNO2, DDQ/Sc(OTf)3, etc., were unsuccessful. Furthermore, Pd-catalyzed intramolecular C–C bond formation reactions on tetrabromide 7 also failed, see: Saegusa Y, Ishizuka T, Komamura K, Shimizu S, Kotani H, Kobayashi N, Kojima T. Phys. Chem. Chem. Phys. 2015; 17: 15001 ; details of the oxidation reactions of 3(M) will be reported elsewhere

We were unable to obtain good elemental analysis values for pyrene-substituted porphyrins. meso-Tetraphenylporphryin (TPP) and its metal complexes are known to behave as porphyrin sponges in which the TPP lattices incorporate solvent molecules like a sponge, see:
