   Abstract:
   The luminescence of heterocyclic compounds on Whatman 4 filter paper, a substrate frequently used in room-temperature phosphorimetry, is investigated with the view to characterizing the molecule-substrate interaction. Three molecules having known spectroscopic properties, benzo[a]phenazine, 1,4-diazatriphenylene, and "Michlers ketone", adsorbed on the substrate and dissolved in rigid solvents, are used as luminescent probes to investigate the nature of adsorbate-substrate interaction. The results indicate that the paper substrate provides a very polar environment with high hydrogen-bonding activity for the adsorbed species. © 1986 American Chemical Society.
