One-Step Synthesis of High Pure Tris(8-hydroxyquinoline)aluminum for Optics and Photonics

A simple method of synthesis of high pure tris(8-hydroxyquinoline)aluminum (Alq(3)) from commercial available 5N Al(2)O(3) and 8-hydroxyquinolinol has been developed. One-step exchange chemical reaction has been conducted under controlled 8-hydrixyquinoline vapor at a temperature of 190–240 °C with...

Sumario:A simple method of synthesis of high pure tris(8-hydroxyquinoline)aluminum (Alq(3)) from commercial available 5N Al(2)O(3) and 8-hydroxyquinolinol has been developed. One-step exchange chemical reaction has been conducted under controlled 8-hydrixyquinoline vapor at a temperature of 190–240 °C with water removal by phosphorus anhydride. According to analysis of inductively coupled plasma mass-spectrometry, the chemical purity of synthesized Alq(3) was 99.998 wt%. Photoluminescence of the synthesized Alq(3) has been measured and slightly differed from those of Alq(3) obtained by traditional organic synthesis.
