[Display omitted] •Zinc oxide (ZnO) has outstanding physical and chemical properties, making it a highly functional material.•Porphyrins and chlorophylls are fundamental and ubiquitous pigments in natural systems.•Porphyrin derivatives are excellent candidates for the synthesis of new organic–inorganic hybrid materials.•The combination of porphyrins and ZnO can also lead to the development of a new class of hybrid materials.•Band alignment of porphyrin/ZnO hybrids and their various applications is an important scientific area. The use of materials based on semiconducting oxides is taking an important place in modern chemistry. The application of such materials to catalysis, photocatalysis, and other fields is producing more and more scientific and technological advances every year. Because of its catalytic, electrical, optoelectronic, and photochemical capabilities, zinc oxide (ZnO) is a widely utilized substance in a variety of industries, including sensors, field emission devices, biological and biomedical printing, and security printing. On the other side, porphyrins are versatile biomimetic molecules with multiple functions that are created by condensing pyrrole with aromatic aldehydes. By introducing various peripheral functional groups or metal atoms into the core of the porphyrin, it is possible to modify the structure of the porphyrin synthetically. Consequently, numerous porphyrin derivatives can be synthesized with remarkable optoelectronic properties. The combination of porphyrins and ZnO can also lead to the development of a new class of hybrid materials due to the interaction of their optical, electronic, and chemical properties. In addition, it is possible to control the morphology as well as the reactivity of the hybrid material during the synthesis process, aside from the individual properties of porphyrins and ZnO. This review intends to present the evolution of those ZnO/porphyrin hybrid compounds and point to future research trends in this vital field.
