The results of cyclic 1 voltammetry measurements imply that all these compounds have a higher electron affinity (EA) than 2-(4-biphenyl)-5-(4-tert-butyl phenyl)-1, 3, 4-oxadiazole (PBD) which implies that PATT could be acting as better electron acceptors than widely used electron transporting material PBD.展开更多
Two series of solid complexes of rare earth nitrates and picrates with the "back-to-back" terpyridine, 6′,6″-bis(2-pyridyl)-2,2′:4′,4″:2″,2′″-quaterpyridine (L) have been synthesized.

These complexes have been characterized by elemental analysis, conductivity measurements, thermal analysis and IR spectroscopy. At the same time, the luminescent properties of the Eu(Ⅲ) and Tb(Ⅲ) complexes were also studied.展开更多
