Abstract
• QDs-TPP hybrid structures have higher SO generation compared to free TPP. • MCD spectra confirm TPP remain monomers on QDs surface in hybrid structures. • FRET fully used to generate SO as there are no new nonradiative channels in structures. Photophysical properties of hybrid structures based on CdSe/ZnS quantum dots (QDs) and tetraphenylporphyrin (TPP) molecules have been studied. The hybrid structures are characterized by higher singlet oxygen (SO) generation compared to free TPP molecules due to high intracomplex Förster Resonance Energy Transfer (FRET) efficiency and saving TPP in the monomeric form in the hybrid structures. We show that all energy transferred from QDs to TPP is fully used to generate singlet oxygen since there are no new nonradiative channels in the structures. We believe that our result will stimulate renewed interest in QD based structures with photosensitizers as theranostics agents.
