Directed Energy Transfer in Luminescent Coordination Networks

点击翻译按钮获取中文摘要

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.
