Using NMR to Identify Potential Geometric Isomers of Metal Chelate Systems
EMSL Project ID
3572
Abstract
The primary basis for this research is to understand the fundamental characteristics of a class of small molecules essential to the fabrication of organic light-emitting displays (OLEDs). Since the mid-1980s and the patent of the first efficient electroluminescent device, researchers have investigated many aspects related to OLEDs such as optimization of materials, charge conduction mechanisms, and barrier coatings. To fully understand these properties, we propose a fundamental approach must be taken to understand the chemistry of these small molecules. To that end, we propose to use Nuclear Magnetic Resonance (NMR), specifically 1H, 13C, and variable temperature, to identify the isomeric structure of these molecules. Using NMR to analyze synthesized and purified materials will specifically address questions raised in recent literature publications regarding the isomeric structure of these molecules. Our goal will be to use NMR in conjunction with other methods to formulate a better understanding of the fundamentals of these molecules. A better fundamental understanding of these small molecules is essential in the understanding of device characteristics and charge conduction mechanisms.
