Self-assembled monolayers (SAMs) have been establishedas crucialinterlayers and electronically active layers in organic electronicdevices, such as organic light emitting diodes (OLEDs), organic photovoltaics(OPVs), organic thin film transistors (OTFTs), and nonvolatile memories(NVMs). The use of self-assembling functionalized organic moleculesis beneficial due to mainly three advantages compared with commonthin film deposition approaches. (1) Molecular self-assembly occurswith surface selectivity, determined by the interaction between thefunctional anchor group of the organic molecules and the target surface.(2) The film thickness of the resulting layers is perfectly controllableon the angstrom scale, due to the self-terminating film formationto only a single molecular layer. And finally, (3) the wide variabilityin the chemical structure of such molecules enables different SAMfunctionalities for devices, ranging from electrical insulation tocharge storage to charge transport. The SAM approach can be furtherexpanded by employing several functionalized molecules to create mixedSAMs with consequently mixed properties. [ABSTRACT FROM AUTHOR]
