标题 :Alkynylplatinum (II) terpyridine system coupled with rhodamine derivative: interplay of aggregation, de-aggregation and ring-opening processes for ratiometric luminescence sensing
发明人：WONG KEITH MAN CHUNG
权利人:UNIV SOUTH SCIENCE & TECHNOLOGY CHINA
摘要:The synthesis and characterization of a platinum (II) terpyridine system tethered with a latent organic dye of rhodamine derivative as colorimetric and fluorescent sensory moiety has been reported to show selective Hg2+ ion sensing behavior. The interplay of aggregation/de-aggregation behavior of the alkynylplatinum(II) terpyridine complex and the ring-opening process of rhodamine derivative has been investigated. The spectral change of aggregation NIR emission at 800 nm and rhodamine fluorescence at 585 nm provides a possible ratiometric luminescence measurement. Morphological studies from TEM and SEM images showing nanospherical structures confirmed the aggregation in the absence of Hg2+ ion.
