The laboratory of University at Buffalo chemistry professor Luis A. Colón, in partnership with Molecular Glasses, Inc. will develop a new environmentally benign purification process to be implemented in the manufacturing of novel Organic Light Emitting Diode (OLED) materials that are used in displays on devices such as cell phones, tablets, and flat screen TVs. The purification approach is based on supercritical fluid chromatography (SFC), a technology that provides scaleup purification capabilities with the added benefit of minimizing the use of organic solvents in the purification process. The new purification method will allow Molecular Glasses, Inc. to improve reproducibility and replace current methodology that often has lacks the reproducibility to achieve the required purity of their novel OLED materials. The new purification process based on SFC will also enable the production of materials at a reduced manufacturing cost.
