چکیده انگلیسی
A highly efficient deep blue emitting material based on anthracene core structure, 9,10-bis-[4-(2-(4-naphthalene-1-yl-phenyl)-vinyl)-phenyl]anthracene (NSA), was synthesized and the device performances of blue organic light-emitting diodes (OLEDs) with NSA as an emitting material were investigated. High efficiency value of 7.75 Candela (cd)/A was obtained in NSA blue devices compared with 3.6 cd/A of 9,10-bis(4-(2,2-diphenylvinyl)phenyl anthracene devices. The introduction of a phenylanthracene core and a rigid naphthylphenyl side group gave high thermal stability due to non-coplanar structure and limited intermolecular interactions, resulting in high efficiency in blue OLEDs.
