报道了具有独特光物理性质的环金属化C ^ C *铂(II)配合物的合成和表征,聚集诱导了量子产率的提高,同时降低了磷光寿命。另外,通过激发波长的变化引起发射颜色的变化。这些配合物的聚集行为受取代基的空间需求控制。这些配合物的光物理性质通过发射激发矩阵分析(EEM)进行研究。单体配合物是出色的室温磷光蓝色发射体,最大发射峰低于470 nm,量子产率高达93%。
characterization of cyclometalated C^C* platinum(II) complexes with unique photophysical properties, aggregation induced enhancement of the quantum yields with a simultaneous decrease of phosphorescence lifetimes, is reported. Additionally, a change of emission color is induced by variation of the excitation wavelength. The aggregation behavior of these complexes is controlled by the steric demand of

prognosis. Thus, inhibiting CDC25 activity in cancer treatment appears a good therapeutic strategy. In this article, refinement of the initial hit XDW-1 by synthesis and screening of a focused compound library led to the identification of a novel set of imidazopyridine derivatives as potent CDC25 inhibitors. Among them, the most potent molecule was CHEQ-2, which could efficiently inhibit the activities
