将四阳离子芘衍生物(Py~(4+))和三(联吡啶)Ru(II)(Ru~(2+))杂化到合成粘土表面。在粘土表面观察到激发态Py~(4+)发射猝灭的显著刺激作用，其表观猝灭速率常数很大(Kq=7.4±0.7×1015L·mol~(-1)·s~(-1))。
Tetra-cationic pyrene derivative (Py4+) and tris(bipyridine)ruthenium(II) (Ru2+) were hybridized onto the surface of a synthesized clay. We observed the remarkable stimulation of excited Py4+emission quenching on the clay surface, with a very large apparent quenching rate constant (kq= 7.4 ± 0.7 × 1015L mol–1s–1).
