New advances in MOFs photonics and applications
Metal-Organic Frameworks (MOFs), a class of crystalline porous compounds, have emerged as smart materials with
a wide range of uses and applications. In this Lecture, I will talk about our results exploring the spectroscopic and
photodynamical properties of a series of Zr-based MOFs and their possible uses in nanophotonics, photocatalysis and
detection of explosive molecules. We investigated the photoproperties of Zr-NDC MOF, which is made of Zr-clusters and
2, 6-naphthalene dicarboxylate linkers. We have incorporated different dyes into the MOF porous structure and showed the
occurrence of energy transfer processes from excited MOF to the trapped dyes. We have also studied the photoproperties of Zr-
NDC and a mixed-linker Zr-MOF (Zr-NADC) by using transient absorption techniques. We have established the formation
of a charge separated state in both MOFs. Upon excitation, an ultrafast ligand-to-cluster charge transfer process takes place,
leading to the formation of the related long-lived charge separated state. I will also show results on efficient light harvesting
within C153 at Zr-Based MOF embedded in a polymeric film and the use of two new functionalized mixed-linkers MOFs
(Zr-NDC/To1 and Zr-NDC/To2) as fluorescent sensors of nitroaromatic explosive molecules. These results shed new light
on the photoproperties of different luminescent MOFs and their possible photonics applications, opening the way for further
investigations and giving clues to new developments of smarter MOF materials.
