Project: Optical Sensing and Energy Transfer in Luminescent and Conductive COORNET Mixed-Matrix Membranes
Abstract: The project partners focus on the synthesis and characterization of luminescent MOF systems as particles and polymer composites, as well as neat thin films. The luminescence of the MOF can have its origin in several processes and conditions. In the MOF, metal-centres, e.g. from the lanthanide series, such as Tb, Eu and Sm, interact with ligands that act as sensitizers for luminescence resulting in an increase in the luminescence efficiency. In addition, chromophores and luminescent metal ions can be implemented into the lattices of non-fluorescent MOFs to achieve luminescence properties. The focus of the project lies in the fundamental understanding of energy transfer processes, their mechanisms and the controlled modulation of luminescence. An integration into chemical and gas sensor devices as neat-MOF thin film, or polymer MOF composite membranes (MMMs) are planned. Hereby, the detection of analyte via changes in luminescence processes, the sensitivity of the sensor and the cross selectivity are of main fundamental interest, which will be investigated in comparison of MOFs/MMMs/SURMOFs.
