Contemporary applications in optics, medicine, solar cells, or material science are increasingly reliant on unsymmetrically substituted porphyrins. Due to their widespread applications and rise in demand we undertook a comparative analysis of synthetic strategies for meso-substituted porphyrins and present the synthesis of five different series of so-called A2BC push-pull porphyrins. The synthetic pathways used were applied to both 5,15-substituted and 5,10-substituted porphyrins, showcasing their flexibility and adaptability for different needs. Our approach combines well-known reactions with a strategic and logical stepwise functionalization allowing researchers to change and modify the electronic properties of these systems at various points of the syntheses. This facilitates the easy optimization of the synthesis of systems of current interest, for example, porphyrins for dye-sensitized solar cells (DSSCs) or for use in nonlinear optics, as well as fast generation of compound libraries.

A compound that can be used as a donor material in organic photovoltaic devices comprising a non-activated porphyrin fused with one or more non-activated polycyclic aromatic rings or one or more non-activated heterocyclic rings can be obtained by a thermal fusion process. By heating the reaction mixture of non-activated porphyrins with non-activated polycyclic aromatic rings or heterocyclic rings to a fusion temperature and holding for a predetermined time, fusion of one or more polycyciic rings or heterocyclic rings to the non-activated porphyrin core in meso,β fashion is achieved resulting in hybrid structures containing a distorted porphyrin ring with annulated aromatic rings. The porphyrin core can be olygoporphyrins.

Porphyrin compounds are provided. The compounds may further comprise a fused polycyclic aromatic hydrocarbon or a fused heterocyclic aromatic. Fused polycyclic aromatic hydrocarbon s and fused heterocyclic aromatics may extend and broaden absorption, and modify the solubility, crystallinity, and film-forming properties of the porphyrin compounds. Additionally, devices comprising porphyrin compounds are also provided. The porphyrin compounds may be used in a donor/acceptor configuration with compounds, such as C60.

(Figure Presented) Sticking together: Direct fusion of pyrene rings with diporphyrins can be achieved without prior activation of aromatic rings. This simple method gives pyrene-diporphyrin hybrids (see picture, C (pyrene) red, C (porphyrin) dark blue, N light blue, Zn green) with a high near-infrared (NIR) absorption that reaches the wavelengths required for use in telecommunications.
