Low-temperature luminescence of purine derivatives: Salt effects

Xanthines (caffeine, theophylline and theobromine) and purine have very low quantum yields of fluorescence in ethanol and acetonitrile solutions at room temperature (Φf < 10-3; naphthalene as fluorescence reference). At 77 K xanthines show good fluorescence and phosphorescence spectra, while...
