Abstract
A simple method of synthesis of high pure tris(8-hydroxyquinoline)aluminum (Alq3) from commercial available 5N Al2O3 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 Alq3 was 99.998 wt%. Photoluminescence of the synthesized Alq3 has been measured and slightly differed from those of Alq3 obtained by traditional organic synthesis.

Summary
In the last two decades, a large effort has been directed towards development of wearable/implantable electronics based on organic semiconducting materials. Organic semiconducting material technologies are interesting for their fine-tuning of characteristics due to the large variability of chemical formulas at high productivity and low production costs. To date OLED technologies have become widespread in various fields of techniques: perfect TV displays, energy efficient lighting devices, IR sensors and displays for medical application, etc. Materials and Devices, 2nd ed.; CRC Press: New York, NY, USA, 2016.
