Abstract: Abstract Novel fluorescent 4-alkynyl coumarins were rapidly and efficiently synthesized by Sonogashira coupling of readily accessible coumaryl triflates. The photophysical properties of the predominantly highly fluorescent compounds were experimentally studied by absorption and fluorescence spectroscopy… read more here.
