An organic electronic device which comprises a metal anode 4 and a hole injection layer 6, said device further comprising a self-assembled monolayer (SAM) 22 between the metal anode 4 and the hole injection layer 6, the SAM 22 comprising a compound which has a moiety which is capable of adsorbing onto the surface of the metal anode 4 and a hydrophilic moiety. Also disclosed is a method of forming said device. Further disclosed is a material which can form a SAM which can passivate a metal anode in an organic electronic device and prevent oxidation of said anode, where the SAM contains a compound which has a hydrophilic group which improves the wettability of the surface of the anode. Also disclosed is a compound which can form a SAM, where the SAM reduces the contact resistance between a metal anode and a hole injection layer and contains a hydrophilic moiety. The hydrophilic moiety can be a derivative of benzotriazole or indazole, which has a hydroxyl, carboxy, carbonyl or thio hydrophilic substituent. The hydrophilic moiety can also be a thio compound with a hydrophilic tail, preferably a thioalkane or thioalkene. |
