            The project focuses on the design and synthesis of novel chiral fluorescent materials that
            polarized light in the green-to-red spectral range. These compounds will be based on small
            molecules containing carbon, nitrogen, and/or boron, incorporating quinolizinium or quinac

            fluorophores and cyclic aza-bora functionalities. The molecular frameworks will feature ei
            helical chirality or a combination of helical and planar chirality, in some cases conjugat

            [2.2]paracyclophane scaffolds. The use of environmentally benign elements aims to provide 
            alternatives to existing emitters containing heavy metals, with potential applications in 
            and advanced photonic technologies.


            The project builds on preliminary and largely unpublished results from the participating l
            Previous work demonstrated that helical azonia salts can display strong yellow-to-red fluo

            emission properties tunable through modification of the helical core. In parallel, newly d
            cycles have been shown to emit green fluorescence, further supporting the feasibility of a
            emission range. The research will pursue both racemic and enantioselective synthetic pathw

            molecules, followed by comprehensive characterization of their photophysical and chiroptic
            guide the development of improved CPL-active emitters.


            Collaboration between Charles University, the University of Geneva, and Heidelberg Univers
            supported through three mini-symposia hosted in Prague, Geneva, and Heidelberg, complement
            online meetings. These activities will facilitate knowledge exchange, interdisciplinary tr

            integration of PhD students and early-career researchers into an active European research 
            combining expertise in organic synthesis, materials chemistry, and advanced spectroscopy, 
            contribute to the development of innovative, sustainable light-emitting materials and stre

            collaborative links between the partner institutions.
