Spectroscopic properties of the complexes formed by graphene oxide and derivative of porphyrin with aryl groups

Hybrid systems based on graphene oxide (GO) modified by organic molecules with the properties of donor and acceptor are very popular. The researches made in the last few years show that these structures have a really interesting photoelectrochemical properties. The ability of graphene oxide to effectively capture electrons, e.g. of porphyrins suggests the potential use of such materials in photovoltaics and molecular optoelectronics. This implies that further research of this group of molecular materials is very important from the point of view of their applications in diodes and transistors. The goal of the research was to create new hybrid systems with donor-acceptor properties, consisting of graphite oxide and porphyrin 5,10,15,20-Tetrakis (4-hydroxyphenyl) -21H, 23H-porphine. The resulting hybrid structure has been characterized by spectroscopic investigation in a wide spectral range from ultraviolet to infrared
