The work presents a promising and novel route for the synthesis of azine derivatives with strong acceptor behavior. In this case, the on-surface synthesis consists on a thermal annealing process where p-aminophenol molecules, deposited on Cu(110), undergo an azine-coupling reaction. Both, the chemical reaction mechanism and the charge transfer process induced by the substrate were followed by complementary surface techniques (nc-AFM\/STM, XPS, NEXAFS and LEED) as well as by theoretical calculations. We observe that Cu(110) catalyzes a chemical reaction between two p-Ap molecules giving rise to a quinoneazine molecule. The resulting molecule accepts 1.2e- from the substrate, which induces a charge redistribution with recovering of aromaticity, leading to an azo compound behaviour.<\/p>\n

The study opens the door for the use of on-surface synthesis protocols to fabricate \u00e0 la carte donor or acceptor interfaces on organic heterostructures.<\/p>\n","protected":false},"excerpt":{"rendered":"
