Organic electronic devices: Low work function metal surfaces are obtained with the adsorption of the molecular donor 9,9′-ethane-1,2-diylidene-bis(N-methyl-9,10-dihydroacridine) (NMA). This reduces the electron injection barrier (EIB) for the subsequently deposited electron transport layers (ETLs) and permits continuous tuning of the EIB via pre-coverage of metal electrodes with sub-monolayers of NMA (see figure).
