Research Abstract

We created new molecular release systems capable of remotely deliver biologically active molecules under light irradiation. To this end, we combined the high storage ability of porous coordination polymers (PCPs), a new class of crystalline materials assembled by organic linkers and inorganic joints at the molecular scale, with the photo-thermal properties of gold nanorods (GNRs) into designed mesoscopic composite materials. These materials consisted in core shell structures composed of a GNR core and an aluminum-based PCP shell. The creation of such mesoscopic structures enabled the implementation of unique motion-induced molecular release, triggered by the highly efficient conversion of optical energy into heat that occurs when the GNRs are irradiated into their plasmon band. Temporal control of the molecular release was demonstrated with anthracene as a guest molecule (priorly immobilized within the pores of the PCP shell) and fluorescent probe by fluorescence spectroscopy.
