Abstract

A facile DAR (diphenylamine-4-diazonium-formaldehyde resin) assisted layer-by-layer (LbL) assembly of ultrathin organic film of aromatic compounds has been investigated. The multilayer of pyrene or anthracene was fabricated through simple dipping of the glass slide into the mixed solution of DAR with the target compounds. In this method, DAR acted as an assistant compound to help the assembling of the aromatic compounds. Such a convenient deposition method not only reserves the advantages of the traditional LbL technique but also simplifies the technique and extends the effectiveness of LbL technique to small molecules without any charge.
