Novel dinuclear Eu(III)-β-diketonates with a branched tetraphosphine tetraoxide ligand, TDPBPO and TDPPPO, were developed. They have sharp red emissions and excellent quantum yields, and are promising candidates for LED devices, security media, and sensing for their pure and bright photoluminescence.
