Overall 21 imidazole-based chromophores have been synthesized and fully characterized. The imidazole core was systematically substituted with donors (NMe(2) and OMe) and acceptors (NO(2) and CN groups) additionally separated from the imidazole by pi-spacers such as 1,4-phenylen, styryl or thiophen-2-yl in order to finely tune their intramolecular charge transition. The target chromophores were further investigated by UV/Vis spectroscopy as potentially NLO-active compounds.
