This book describes the luminescence mechanism of polynuclear lanthanide complexes, focusing on energy transfer processes using a combination of experimental and theoretical approaches. Lanthanide complexes show intense luminescence from the lanthanide ion through sensitization by the organic ligands. The high chromaticity of the emission and the long lifetimes of the complexes are particularly attractive for applications such as organic light-emitting diodes and bioprobes. Polynuclear lanthanide complexes (coordination polymers and clusters) have attracted considerable interest for functionalization by energy transfer between lanthanide ions. At the same time, such extra processes complicate the luminescence mechanism, hindering the rational design of functional polynuclear lanthanide complexes. Firstly, the book explains the principle of the theoretical methods, and then describes the concentration-quenching mechanism in coordination polymers. It also examines the effect of intrinsic spin–orbit coupling arising from lanthanide ions on the ligand-to-lanthanide energy transfer efficiency and the mechanism of back energy transfer (the opposite of sensitizing energy transfer) in lanthanide clusters. This sets the stage for the final topic: the suppression of back energy transfer by energy transfer between lanthanide ions in lanthanide clusters, which is of critical importance, showing that the lanthanide clusters can be considered a new generation of functional and efficient luminescent material and could also provide a breakthrough in lanthanide photophysics.

Research on metal-containing polymers began in the early 1960's when several workers found that vinyl ferrocene and other vinylic transition metal u -com plexes would undergo polymerization under the same conditions as conventional organic monomers to form high polymers which incorporated a potentially reactive metal as an integral part of the polymer structures. Some of these materials could act as semi-conducters and pos sessed one or two dimensional conductivity. Thus appli cations in electronics could be visualized immediately. Other workers found that reactions used to make simple metal chelates could be used to prepare polymers if the ligands were designed properly. As interest in homo geneous catalysts developed in the late 60's and early 70's, several investigators began binding homogeneous catalysts onto polymers, where the advantage of homo geneous catalysis - known reaction mechanisms and the advantage of heterogeneous catalysis - simplicity and ease of recovery of catalysts could both be obtained. Indeed the polymer matrix itself often enhanced the selectivity of the catalyst.
