Description:
In this project we propose the design, synthesis, and versatile application of organic push-pull molecules featuring intramolecular charge-transfer. Four principal classes of compounds were envisaged - (thio)barbituric acids-derived systems, donor 3,6-disubstituted diketopyrrolopyrroles, Thdione derivatives resembling indane-1,3-dione moiety, and imidazolium- and pyridinium betaine derivatives. The final property tuning will be accomplished in terms of variation of the appended donors and acceptors, elongation of the p-linker and auxiliary pendants, and counter ion replacement. Synthesized compounds will be investigated as NLO-active chromophores upon embedding into the polymeric matrix or inorganic carrier, NLO-active ionic liquids, photovoltaic devices, pH-induced and photochromic NLO-switches, and fluorophores. Strong (inter)national cooperation with renowned scientist has already been established in this respect.
