Organometallic Synthesis: Photofunctional Molecular Materials
Photofunctional molecular materials play a pivotal role in many photonic applications including organic electronics, information storage, encryption, signaling, bioimaging, medical diagnostics, and therapy. This stimulates the development of tunable, tailorable, responsive, and adaptive chromophore systems. Diverse combinations of organic and inorganic constituents can significantly broaden the scope of optical properties.
We are interested in the elaboration of preparative methodologies and studying the physical behavior of novel organometallic, organoelement and inorganic compounds using an extensive interplay of experimental and computational approaches.
In particular, our research encompasses molecular design of light-emitting molecular materials, evaluation of their photophysical performance as a function of molecular structure and weak intra- and intermolecular interactions. The areas of our studies cover synthetic organometallic chemistry of late transition metals, self-organizing metal-based supramolecular systems (particularly those of coinage metals), organophosphorus compounds, and non-covalent interactions.
