Directed Energy Transfer in Luminescent Coordination Networks

该项目的目标是实现具有明确定义的、非统计的金属分布的基于稀土的异金属COORNET结构，该分布显示涉及稀土光活性中心的能量转移(ENT)。为此，将合成基于三价稀土离子和d-嵌段发光团的新型CoORNETs，并分析与ENT相关的光物理性质，并将其与网络结构和电子参数相关联。重点介绍了具有近红外-可见光上转换(UC)发光的COORNETs的发展。

The goal of the project is the realization of lanthanoid-based, heterometallic COORNET architectures with well-defined, non-statistical metal distributions that show energy transfer (EnT) involving lanthanoid photoactive centers. For this purpose, new COORNETs based on trivalent lanthanoid ions and d-block luminophores will be synthesized and the photophysical properties relating to EnT will be analyzed and correlated to the structural and electronic parameters of the network. In particluar, emphasis will be given to the development of COORNETs with near-IR-to-visible upconversion (UC) luminescence.
