摘要: Abstract The photophysical behaviours of anthracene in zeolite Y were investigated using various steady state spectroscopic methods and a picosecond time-resolved fluorescence technique. A 129 Xe nuclear magnetic resonance (NMR) study shows that molecules can be optimally intercalated into the supercages Na + - Cu 2+ -exchanged at 570 520 K respectively. Anthracene introduced supercage excimeric with lifetime several nanoseconds, as well monomeric 300 ps. excimer forms immediately on absorption photon. intercalation electron spin (ESR) signals bands attributable to stable, ground cation radical, ion trapped copper cluster, indicating charge transfer from or cluster. excitation energy is quenched rapidly by presence ion.
