Synthesis of fluorinated first generation starburst molecules containing a triethanolamine core and 1,2,4-oxadiazoles

Abstract

5-Pentafluorophenyl-1,2,4-oxadiazoles, differently substituted at C(3), have been synthesized and used to functionalize the aliphatic primary hydroxyl functionalities of triethanolamine, under mild conditions. UV-visible absorption and emission spectra are reported, for both tri- and difunctionalised molecules, showing their potential applications as light-emitters in optoelectronic devices.
