Bio-inspired materials for electron donors and charge-transfer complex formation based on the imidazopyrazinone luciferin core
The electron-donating properties of 2-phenyl- and 2-methylimidazo[1,2-a]pyrazin-3(7H)-ones were confirmed by the oxidation potentials. The I/I molecular complex from the former and TCNQ was characterized by means of X-ray crystallographic analysis, and the charge-transfer degree was estimated to be 16% from the IR nitrile stretching bands.
