摘要: Abstract We report the simultaneous formation of mono- and dication (known as diacid) radicals during photo-oxidation free-base tetraphenylporphin by selective laser excitations using resonance Raman optical absorption techniques. During process in carbon tetrachloride, addition even a small quantity tetrahydrofuran leads to along with monocation radical. A mechanism di- is proposed.
