D’Andrade, Brian W.; Datta, Shubhashish; Forrest, Stephen R.; Djurovich, Peter; Polikarpov, Eugene; Thompson, Mark E. published the artcile< Relationship between the ionization and oxidation potentials of molecular organic semiconductors>, Recommanded Product: Ir(p-F-ppy)3, the main research area is oxidation potential mol organic semiconductor HOMO.
A relation between the energy of the HOMO and the oxidation potential of mol. organic semiconductors is presented. Approximating mols. as dipoles consisting of a pos. charged ion core surrounded by an electron cloud, the HOMO energy (EHOMO) is calculated as that required to sep. these opposite charges in a neutral organic thin film. Also, an anal. of image charge forces on spherical mols. positioned near a conductive plane formed by the electrode in an electrochem. cell is shown to explain the observed linear relation between EHOMO and the oxidation potential. The EHOMO’s of a number of organic semiconductors commonly employed in thin film electronic devices were determined by UPS, and compared to the relative oxidation potential (VCV) measured using pulsed cyclic voltammetry, leading to the relation EHOMO = -(1.4 ± 0.1) × (qV CV) – (4.6 ± 0.08) eV, consistent with theor. predictions.
