一种新颖的空穴阻挡材料的合成、表征与空穴阻挡特性研究
Synthesis, characterization and study of hole-blocking performance of novel hole-blocking material
摘要
Abstract
MDBP (meta-linkage double-oxygen bridged biphenyl derivatives) is synthesized in terms of Yamamoto reaction. The analyses of cyclic voltammetry and Uv-Vis spectra indicates that MDBP has lower HOMO level (-6.12 eV) and higher oxidation potential (-2.S eV). The effect of thickness of MDBP layer and driving voltage on hole-blocking performance are discussed using multilayer organic light-emitting devices. The results indicate that the ability of blocking holes of MDBP layer depends on its thickness and driving voltage. In addition, white-light-emitting devices based on MDBP as hole-blocking laye is prepared, and its performance is also discussed.关键词
