光致发光配合物[Au~2(μ-PNP)~3](ClO~4)~2(PNP=2,6-双二苯基膦吡啶)具有一个空腔，作为一个主体配合物，当客体分子尺寸和性质特点匹配时，主客体分子相互作用，主体配合物光致发光性能和谱学性质发生变化。利用电子吸收光谱、^3^1P核磁共振波谱、发射光谱等方法，对不同客体分子存在下，配合物光物理性质改变情况作了深入的讨论。

The photoluminescent complex [Au~2(μ-PNP)~3](ClO~4)~2, PNP=2,6-bis (diphenylphophino) pyridine, which has an open cavity, can serve as a host-complex. When the size and character of the host match with those of the guest, the host and the guest may bind to each other. the changes in the photophysical properties of the complex caused by different guest molecules are explored by using electronic absorption, ^3^1P NMR and emission spectrometry.
