Description
技术领域
本发明涉及弱光致光子频率上转换技术领域,具体涉及一类基于邻菲啰啉金属配合物的三线态-三线态湮灭上转换光敏剂及其在生物分子检测方面的应用,以及一种双组份三线态-三线态湮灭上转换体系。
背景技术
三线态-三线态湮灭(TTA)上转换是由光敏剂和发光剂组成的双组份体系,通过Dexter能量转移实现频率上转换。具体过程如下:I)光敏剂吸收激发光能量,将其储存至三线态;II)经过三线态-三线态传输过程将能量传递至发光剂的三线态;III)两个三线态激发态发光剂分子经过三线态-三线态湮灭过程,一个发光剂分子回到单线态基态,另一个获得它们的三线态能量被激发至更高的单线态激发态;IV)单线态激发态发光剂分子通过辐射跃迁回落至基态,发出延时荧光。
与传统的双光子吸收相比,TTA上转换具有泵浦能量低、激发和发射波长可调等特点,在太阳能转换利用、信息存储和生物检测等方面具有潜在应用价值。在TTA上转换体系中,光敏剂作为TTA上转换的能量吸收窗口和能量传递者,其光物理性质对TTA上转换性能具有至关重要的作用。因此,开发高效的TTA上转换光敏剂是提高能量利用率,实现其应用价值的重要保证。

本发明实施例还提供了所述三线态-三线态湮灭上转换光敏剂于生物分子检测中的应用。
较之现有技术,本发明的有益效果在于:
(1)本发明实施例提供的基于邻菲啰啉的三线态-三线态湮灭(TTA)上转换光敏剂,与发光剂可以组成双组份TTA上转换体系,具有优异的弱光上转换效率。通过与发光剂之间的三线态能量转移,将长波长的光转换为短波长的光,这一过程只需通过泵浦光源光强为6mW·cm-2的弱光场实现。
(2)上转换体系泵浦光源光强低至6mW·cm-2,太阳光激发下即可实现获得上转换荧光,大大拓展了TTA上转换的应用。
(3)本发明实施例提供的三线态-三线态湮灭(TTA)上转换光敏剂,可以与生物分子发生相互作用,从而可以应用于TTA上转换对生物分子的检测领域,对生物分子的检测分析具有潜在应用。
