Registration of radical anions of Al, Ga, In tris-8-oxyquinolinates by magnetosensitive and spectrally resolved recombination luminescence in benzene solutions

► Radical anions of Al, Ga, In oxyquinolinates form in X-irradiated benzene solution. ► Spectra and relative yields of recombination luminescence for Mq3 were obtained. ► Magnetic field effect yielded hyperfine coupling constants on metal centers.
