Abstract： The new progresses were reviewed on the photofunctional rare earth hybrid materials using or ganically modified siloxanes as linkers. The emphasis was focused on the organically modified siloxanes through the silane crosslinking reagents and excellent photosensitized organic ligands for rare earth ions and the chemically bonded assembly of luminescent rare earth hybrid materials using the multifunctional link ers. The content involved the als constructed by aromatic rare earth hybrid materi carboxylic acid modified siloxanes, the rare earth hybrid materials constructed by betadiketonates （and analogue betadiketonates） modified siloxanes, the rare earth hybrid materials constructed by macrocycle ligands derivatives modified siloxane, the rare earth hybrid materials constructed by nitrogen heterocycle derivatives modified siloxane, the rare earth hybrid materials constructed by polybas ic units and the rare earth hybrid materials constructed by ionic liquid linker modified siloxane. Here we mainly summarized the work of our group. Through the systematically summary, the research facts and future prospects were discussed.
