- Abstract
- In this contribution we explore the capability of biocompatible nanoparticles (NPs) of cationic
amphiphilic cyclodextrins entangling the anionic hydrophilic 5,10,15,20-tetrakis(4-
sulfonatophenyl)-21H,23H-porphyrin (TPPS) to facilitate photoinduced energy and electron transfer
with suitable donor and acceptor guest molecules, by using a combination of absorption, induced
circular dichroism and fluorescence spectroscopy. It is shown that anthracene (AN) and
anthraquinone-2-sulfonate (AQS), chosen as appropriate energy donor and electron acceptor,
respectively, can be trapped within the NPs network. Fluorescence experiments carried out in the
presence and, for comparison, in the absence of NPs provide clear evidence that the amphiphilic NPs
strongly encourage singlet-singlet energy transfer from AN to TPPS as well as photoinduced
electron transfer from TPPS to AQS. In view of the biocompatibility and drug-carring properties of the
NPs used, these results can be of interest from the perspective of designing photo-activated drug
delivery systems. (literal)
