Abstract

Luminescent sensors, light emiting devices, electrical or chemical energy converting systems are usually based on coordination compounds since their properties, such as light absorption, redox potentials and photoreactivity, can be modulated through modification on their structure. These compounds are interesting to be used in the development of direct solar energy conversion into electricity or chemical energy systems. Ruthenium tris-heteroleptic compounds have already been investigated in our research group and, in this project, it is proposed the systematic evaluation of the influence of the conjugation extension of the phenanthroline substituents, focusing on the electron injection efficiency through the triplet excited state. Rhenium(I) polypyridyl compounds are employed on CO2 photoreduction investigations. The main reason is due to these compounds simultaneously act as photosensitizer and catalyst for this process. In this context, the focus of this project is to insert our research group in this field and use the concepts of molecular engineering to obtain rhenium(I) polypyridyl compounds aiming to exhibit higher sunlight harvesting and convert the CO2 into high energy content products. It is also focus of this project investigate the mechanisms involved in both processes. (AU)
