Targeted chromophore molecules, among them primarily (fluorinated) flavins should be embedded as molecular guests into the defined solid-state environment of coordination polymers or MOFs. The embedding should be carried out either by postsynthetic impregnation of the MOF or by in-situ incorporation during MOF synthesis. As such we will add "solid solutions" as a third phase to the study of chromophores, besides the (normal) liquid solutions and pure solid-state. The photophysical properties of the chromophores as a solid solution in the defined solid-state pore-confinement will then be determined in collaboration within the research training group. We expect the photophysical properties of the chromophores in these solid solutions to be different from liquid solution environments. The size, shape and hydrophilicity/hydrophobicity of the pores in the MOFs can be adapted to the chromophore molecules by linker variation to achieve an optimal guest uptake. Partial loading of the MOF for additional separation of the chromophore molecules will be addressed. Further, the photophysical properties of the chromophores will be tried to modify by alteration of the MOF linker and possible other guests based on the theoretical input provided by collaboration within the research training group..
