Study of phenylpyridyldiketopyrrolopyrrole interaction with hydrogen in gas and in acids

Abstract

): In this work, we applied experimental and theoretical techniques to study the influence of hydrogenation on the electrical properties of a derivative of diketodiphenylpyrrolopyrrole – phenylpyridyldiketopyrrolopyrrole (PPDP). From the experimental results and theoretical models it follows that the suitable reaction of PPDP with hydrogen can modulate the material electronic properties (ionization potential, surface potential, conductivity).
