Solution-processible organic light-emitting device based on quinolato-complex supramolecules

Abstract

A new type of supramolecular light-emitting materials Al(SCarq)(3) was synthesized by 5-N-(3-carbazylpropyl)-p-methylaniline-sulfonyl-8-hydroxyquinoline. Via molecular engineering, its solid photoluminescence shows blue-green at 488 nm and two HOMO sites were -5.44 and -5.93 eV. For OLEDs fabrication using spin-coating techniques, the turn-on voltage and the maximum luminescent were 9.6 V and 35.0 cd/m(2), respectively. Due to the electroplex formation, the chromaticity of EL was shifted to green-yellow with 1931 CIEx,y (0.40, 0.47).
