Electrostatically driven resonance energy transfer in “cationic” biocompatible indium phosphide quantum dots

Abstract

InP QDs join the family of cationic nanoparticles as a practical alternative to toxic metal ion based QDs for biological applications.

Azophenine as Central Core for Efficient Light Harvesting Devices

“…Such rates are particularly impressive in the Dexter regime considering the use of both arms (imine and amine), a particularly long bridge (perhaps the longest so far), and the quasi‐right angle formed by the Bodipy and C 6 H 4 C≡CC 6 H 4 linker planes, to perform the efficient double electron exchange. This conclusion is entirely consistent with the fact that the azophenine radical, when acting as a bridging ligand for various transition metals at the N^N sites, mediates exceptionally strong magnetic exchange coupling constants . These fast rates also re‐inforce the recently made conclusion that the ‐NH‐ bridge is prone for efficient electronic communication.…”

“…Azophenine ( 1 , Figure ) and its various cyclized and uncyclized organic derivatives and coordination complexes are renowned to be redox active and on some occasions, catalytic activity was reported⋅ Noteworthy, the ability of tetraazalene radical bridging ligands to mediate exceptionally strong magnetic exchange coupling across a range of transition metal complexes was also demonstrated . However, these uncycled dyes are also known to be notoriously non‐luminescent.…”

Synergistic interactions of cadmium-free quantum dots embedded in a photosensitised polymer surface: efficient killing of multidrug-resistant strains at low ambient light levels

“…Thus the complex formed may allow the occurrence of short-range energy transfer pathways. 55,56 The ability of the QDs and CV to function as a FRET donor-acceptor complex was evidenced by the significant overlap of the QD emission with CV absorbance as illustrated in Fig. 3A.…”

Solvation of quantum dots in 1-alkyl-1-methylpyrrolidinium ionic liquids: toward stably luminescent composites

“…Surface-capping ligands on NPs further enhance the colloidal stability in ILs especially against temperature and concentration-induced agglomeration [1]. Charged ligands are available to control the colloidal stability of NPs in water in terms of electrostatic stabilization [20][21][22][23]. Imidazolium-functionalized surface ligands are often employed to improve the affinity of NP surface to imidazolium-based ILs [24,25].…”
