Porphyrins (PPs) and their derivatives can be found in many natural biological systems and offer potential solutions to a wide range of applications. In plants, PPs are an essential part of the chlorophyll pigment that converts solar energy into chemical energy. Porphyrinoids also have been proven to be efficient sensitizers and catalysts 3 in several chemical processes, including medical applications such as photodynamic therapy. They have been incorporated both as linkers and connectors in metal-organic frameworks (MOFs) and covalent-organic frameworks (COFs). A good light harvesting material efficiently absorbs photons from the highly abundant visible solar spectrum. This property can be probed by UV/Vis spectroscopy.
