A carbon nanotube/inorganic hybrid material was fabricated by coupling Eu(III) complexes onto multi-walled carbon nanotubes (MWCNTs). Successful coupling was verified by XPS measurement where a clear signal from Eu3d was identified. When sonicated in hexaethylene glycol monododecyl ether (C12E6) or sodium dodecyl sulfate (SDS) aqueous solutions, the MWCNTs with Eu-complex attached (denoted as Eu-MWCNTs hereafter) can be dispersed. UV-visible measurements on a dilute dispersion of Eu-MWCNTs in SDS aqueous solution reveal the characteristic absorption from Eu(III) complexes, which gives further proof of the successful coupling. The strong luminescent properties of Eu-MWCNTs allow them to be observed directly under a fluorescence microscope. Eu-MWCNTs can undergo continuous movements in C12E6 or SDS dilute solutions When Eu-MWCNTs are incorporated into the lyotropic liquid crystal phase formed by C12E6 (above 40% by weight), however, movements were hindered. Small angle x-ray scattering measurements showed that Eu-MWCNTs are ordered in the lyotropic liquid crystal. Fluorescence microscopy observations reveal that the luminescent properties of the Eu-MWCNTs were not affected by the liquid crystalline surfactant matrix. The experimental process involved the reaction of [2,2′-Bipyridine]-3,3′-diamine(cas: 75449-26-2).Synthetic Route of 75449-26-2
