Methanol drives the blue emissive complex, [Cu(2)(dppy)(3)(MeCN)](BF(4))(2) (dppy = diphenylphosphino-pyridine), with a head-to-tail arrangement of the three bridging phosphine ligands to convert to its linkage isomer (head-to-head, green emissive) in the solid state, and the transformation could be reversibly realized through recrystallization in different solvents.
Asymmetric light reflectance effect was observed in an anodic aluminum oxide on glass structure. The transmitted light from two sides of the films show the same colors, whereas the reflected light from two sides show complementary colors. The spectra analysis demonstrates that this asymmetric light reflectance effect can be ascribed to the asymmetric geometric structure of nanoscale aluminum networks. This effect may result in applications in many fields, especially in optical communication.
Although luminescent lanthanide-containing molecular complexes are well-known, it is not the case for La3+ with no 4f or 5d electrons, and the few luminescent complexes of La3+ contain luminescent ligands....
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
