Spectroscopic study on a photoluminescent host-guest complex [Au2(μ-PNP)3](ClO4)2

Abstract

The photoluminescent complex [Au2(μ-PNP)3](ClO4)2, PNP = 2,6-bis(diphenylphosphino) 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, 31P NMR and emission spectrometry.

光致發光配合物[Au2（μ-PNP）3]（ClO4）2（PNP=2,6-雙二苯基膦吡啶）具有一個空腔,作為一個主體配合物,當客體分子尺寸和性質特點匹配時,主客體分子相互作用,主體配合物光致發光性能和譜學性質發生變化.利用電子吸收光譜、31P核磁共振波譜、發射光譜等方法,對不同客體分子存在下,配合物光物理性質改變情況作了深入的討論.
