These complex materials impact several areas of technological importance including energy (solar cells), displays (light emitting diodes), electronics (field effect transistors), and health (sensors). These carbon-based small molecules, oligomers or polymers were initially envisioned as replacements for silicon and rare-earth metal(s) based semiconductors widely used today. However, organic materials can be used to produce devices with properties that cannot be attained with inorganic materials, such as color tuning and fabrication on irregular surfaces. Although there are many known issues with organic semiconductors such as the scalability of chemical synthesis and elimination of defects within the materials, many performance improvements can be made to advance these materials towards large-scale manufacturing of \u201dplastic\u201d electronics. Drawing upon my formal training in the area of organic chemistry, I am able to employ an atomic level approach toward developing new organic semiconductors.<\/p>\n<hr \/>\n<p class=\"epsilon uppercase\" style=\"text-align: center;\"><em><strong>Videos from the Jeffries-EL group<\/strong><\/em><\/p>\n<p><strong><em>Take a tour of the Jeffries-EL lab!<\/em><\/strong><\/p>\n<div style=\"width: 1920px;\" class=\"wp-video\"><!--[if lt IE 9]><script>document.createElement('video');<\/script><![endif]-->\n<video class=\"wp-video-shortcode\" id=\"video-5-1\" width=\"1920\" height=\"1080\" preload=\"metadata\" controls=\"controls\"><source type=\"video\/mp4\" src=\"\/el\/files\/2020\/03\/1080p.mp4?_=1\" \/><a href=\"\/el\/files\/2020\/03\/1080p.mp4\">\/el\/files\/2020\/03\/1080p.mp4<\/a><\/video><\/div>\n<p>&nbsp;<\/p>\n<hr \/>\n<p class=\"epsilon uppercase\"><em><strong>21st Century Scientists: Malika Jeffries-EL<\/strong><\/em><\/p>\n<p>In this 21st Century Chemist profile, Iowa State University organic chemist Malika Jeffries-EL explains her work to make less costly, more energy-efficient semiconductors and LEDs from organic, carbon-based materials such as plastics, &#8220;doping&#8221; the organic materials so that they are more conductive.
