Circularly polarized lanthanide luminescence from Langmuir-Blodgett films formed from optically active and amphiphilic Eu(III) based self-assembly complexes

The development of novel chiral amphiphilic self-assembled complexes 13Eu and 23Eu by using Europium(III) directed synthesis is described. These systems form stable Langmuir films at an air-water interface, which were transferred onto solid supports (quartz slides) resulting in stable monolayers that exhibit time delayed Eu(III) centered emission and circular polarized luminescence (CPL) upon excitation of the chiral naphthyl antennae.
