INTERAÇÃO ENTRE PONTOS QUÂNTICOS E COMPLEXOS DE RUTÊNIO: LIMITAÇÕES E POSSIBILIDADES DA AVALIAÇÃO MATEMÁTICA DE UM SISTEMA FLUORÓFORO-SUPRESSOR (F-Q)

Abstract

Quantum dots (QPs) have been extensively discussed in the field of energy, molecular diagnostics and nanotherapeutics. In all the processes studied there are mechanisms of charge transfer and/or energy transfer within this type of assembly, especially in associations with metal complexes. Among them, ruthenium complexes have received special attention due to their possible inclusion in solar energy conversion and the development of theranostic devices in the medical field. Generally the formation of the electron-hole pair or exciplex is considered a pre-association process prior to the energy transfer mechanism. Currently, there is limited understanding of the underlying photophysical processes in this type of conjugate system. Thus, the main objective of this work is to make a mathematical evaluation, using the Stern-Volmer model, of the interaction between quantum dots (CdTe QD) and ruthenium complexes - [Ru(NH3)5(py-x)]2+ - verifying the limitations of the model as well as all the possibilities of understanding the system from this theoretical point of view.
