One/two-photon-sensitive photoacid generators based on benzene oligomer-containing D-π-A-type aryl dialkylsulfonium salts

Novel sulfonium-based D-π-A photoacid generators (PAGs) with a benzene oligomer (from one to four) as a π-conjugated system that are highly photosensitive in the near-ultraviolet region (365 nm) were prepared. The maximum absorption and molar extinction coefficients of the PAGs redshifted and enhanced with the increasing length of the conjugated systems. The quantum yields of PAGs were high (three of them were over 0.6) and improved by adjusting the number of the phenyl rings. The quantum chemical calculation results proved that the molecular configuration and nature of the frontier orbitals are crucial factors which affect PAG performance. Photopolymerization kinetic results demonstrated that these sulfonium-based PAGs were highly efficient cationic photoinitiators, and the i-line sensitivities were evaluated based on the photolithographic performance of the PAG-containing SU-8 resins. In addition, the two-photon absorption cross sections (δ700 nm > 400 GM) matched the requirements needed in the 3D fabrication of polymer microstructures.

AROMATIC TRIAMINE COMPOUND AND ORGANIC ELECTROLUMINESCENT DEVICE USING SAME

Also disclosed is an organic electroluminescent device wherein an organic thin film composed of one or more layers including at least a light-emitting layer is interposed between a cathode and an anode, and at least one layer in the organic thin film contains the aromatic triamine compound by itself or as a component of a mixture. Such an organic electroluminescent device has high luminous efficiency and long life, and the above-mentioned aromatic triamine compound enables to realize such an organic electroluminescent device.

Synthesis and Functional Properties of Strongly Luminescent Diphenylamino End-Capped Oligophenylenes

Two novel homologous series of oligophenylenes (OPPs) symmetrically end-capped with diphenylamino groups and asymmetrically end-capped with anthryldiphenylamino groups were successfully synthesized by a convergent approach with use of palladium-catalyzed homo- and cross-coupling of arylboronic acids. The absorption maxima of both diphenylamino end-capped OPP series do not vary with the chain length although the molar absorptivities increase sequentially. On the other hand, the emission maxima slightly shift to longer wavelengths when the phenylene unit increases in the series. All the diphenylamino end-capped oligomers exhibit very large fluorescence quantum yields (81-89%). They also exhibit low first ionization potentials, corresponding to the oxidation of the triarylamino moiety, which are essentially unaffected by the oligomeric length extension. The good thermal stabilities of these oligomers allowed the fabrication of multilayer light-emitting devices and their investigations.
