New three-coordinate organoboron compounds functionalized by a (1-naphthyl)phenylamino group, B(mes)2(dbp-NPB) (1), B(db-NPB) 3 (2), and B(dbp-NPB)3 (3), have been synthesized. A variable temperature 1H NMR study showed that the aryl groups around the boron center in these compounds have a rotation barrier ~70 kJ mol -1. The new boron compounds are amorphous solids with Tg being 110°C, 171°C and 173°C, respectively. The electronic properties of the new boron compounds were investigated by cyclic voltammetry and UV-visible spectroscopy. All three boron compounds are blue emitters in the solid state. In solution the emission spectra of the boron compounds shift toward a longer wavelength with increasing solvent polarity. In CH 2Cl2, the emission quantum efficiency of the three compounds was determined to be 0.22, 0.27 and 0.23, respectively. Several series of electroluminescent (EL) devices where compounds 1-3 are used as either an emitter/electron transport material, a hole transport material, or a hole injection material have been fabricated and their performance has been compared to the corresponding devices of BNPB, a previously investigated molecule, NPB, a commonly used hole transport material, and CuPc, a commonly used hole injection material. The EL results indicate that the new boron compounds are not suitable as emitters/electron transport materials, but they are promising as hole transport and hole injection materials in EL devices.

A series of new organic dyes containing an electron-deficient diphenylquinoxaline moiety was synthesized and employed as the photosensitizers in dye-sensitized solar cells (DSSCs). The multiple phenyl rings in the peripheral positions of the dye structure provide a hydrophobic barrier to slow down the charge recombination. The photophysical and electrochemical properties of these dyes were investigated in detail. The cell performance and the associated photophysical and electrochemical properties can be easily tuned by the modification of the aromatic fragments within the π spacer. Dye CR204-based DSSC reached the best energy conversion efficiency of 6.49% with an open-circuit voltage of 666 mV, a short-circuit photocurrent density of 14.9 mA cm-2, and a fill factor of 0.66. The IPCE of CR204-based DSSC covers the light-harvesting to NIR region.

A series of novel hole transport materials for organic light-emitting diodes (OLEDs) based on 9,14-diphenyl- 9,14-dihydrodibenzo[a,c]phenazine were synthesized and characterized by 1H NMR and 13C NMR, mass spectrometry and single crystal structure analysis methodologies. The crystal structures of three selected molecules reveal large dihedral angles between different functional units. The electro-optical properties of the materials were examined by UV-vis absorption, photoluminescence spectroscopy and cyclic voltammetry. The HOMO of the materials were between 4.83-5.08 eV, indicating a good match between the HOMO of indium tin oxide (ITO) and the HOMO of light-emitting layer, which renders the promising candidates as hole transport materials for organic light-emitting devices. In terms of the device with the structure of ITO/HTM (60 nm)/Alq3 (50 nm)/LiF (1 nm)/Al (200 nm), the device b using N,N-diphenyl-4′ -(14-phenyldibenzo[a,c]phenazin-9(14H)-yl)-[1,1′ -biphenyl]-4-amine presented a maximum luminance of 17 437 cd m-2 at 10.7 V and kept a high current efficiency (the maximum current efficiency is 2.25 cd A-1) at a high current density (>500 mA cm-2), which illustrates the exploited material possesses good hole transport and stable properties.
