Paper Abstract

An attractive and challenging approach to the construction of robust, structurally precise thin film materials with large second-order optical nonlinearities or electroluminescent characteristics is the covalent self-assembly of arrays of tailored molecular building blocks. In this contribution, we discuss the implementation of self-limiting siloxane self- assembly processes to achieve the fabrication of structurally regular organic LED (OLED) devices. Areas surveyed include: (1) the use of layer-by-layer self-assembly for ITO electrode modification/passivation/hole-electron carrier balancing in vapor deposited devices, (2) the synthesis of chlorosilane- functionalized precursor molecules for hole transport (HTL), emissive layer (EML), and electron transport layer (ETL) self- assembly, (3) the physicochemical and microstructural characterization of the HTL self-assembly process employing a triarylamine precursor, (4) the fabrication and characterization of a hybrid self-assembled + vapor deposited two-layer OLED, (5) the fabrication and characterization of a fully self-assembled two-layer OLED.
