- Synthesis of novel thermally stable electrochromic polynorbornenes containing symmetrical diarylamine and unsymmetrical triarylamine chromophores via ring-opening metathesis polymerisation
-
A new electrochromic norbornene derivative (NB) containing symmetrical diphenylamine and unsymmetrical triphenylamine groups, was synthesised from norbornene amine and unsymmetrical triphenylamine-substituted bromide. NB was used to obtain unsaturated PNB via ring-opening metathesis polymerization using different Grubbs' catalysts, followed by hydrogen reduction to obtain saturated HPNB. PNB and HPNB were highly soluble in common organic solvents such as toluene, xylene, benzene, chlorobenzene, 1,2-dichlorobenzene, and tetrahydrofuran at room temperature. The glass transition temperatures (T g) of PNB and hydrogenated HPNB were 162 °C and 117 °C, respectively. The 10% weight-loss temperatures of PNB and hydrogenated HPNB were 410 °C and 450 °C, respectively. Cyclic voltammogram of HPNB film cast onto an indium-tin oxide (ITO)-coated glass substrate exhibited three reversible oxidation redox couples at 0.52, 0.85 and 1.30 V versus Ag/Ag+ in acetonitrile solution. The electrochromic characteristics of HPNB showed excellent stability and reversibility, with multi-staged colour changes from light yellow to green, dark-blue and purple as the potential changed from 0 to 1.35 V. The colour switching time and the bleaching time of the HPNB were 8.7 s and 4.3 s, respectively, at 1084 nm and 7.9 s and 3.8 s at 879 nm.

- Novel hole transport materials based on N,N′-disubstituted-dihydrophenazine derivatives for electroluminescent diodes
-
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.

We report the chemoselective amination of bromoiodobenzenes with diarylamines by palladium/Xantphos or a ligand-free copper catalyst. The reactions by these two types of catalysts proceeded with a high chemoselectivity and afforded monobrominated triarylamines in good yields.

- Dye-sensitized solar cell utilizing organic dyads containing triarylene conjugates
-
A series of organic dipolar compounds containing a donor (D), a bridge (B), and an acceptor (A), forming a D-B-A type of dyads, were synthesized by convenient methods and were utilized successfully on dye-sensitized solar cells. The central bridges were made of three linearly connected arylene groups, i.e., phenylenes or thiophenylenes. The donor groups were aromatic amines, i.e., either a diphenylamine or a naphthylphenylamine group. The acceptor group was a cyanoacrylic acid, which can be anchored onto the surface of TiO2 in a photovoltaic device. These devices performed remarkably well, with a typical quantum efficiency of 5-7%, and optimal incident photon to current conversion efficiency (IPCE) exceeding 80%. The devices made with a naphthylphenylamine donor group performed slightly better than those made with a diphenylamine donor group. Compounds containing a phenylene-thiophenylene-phenylene bridge group performed better than those with other kinds of triarylene linkages. Their photochemical behaviors were analyzed by using time-dependent density functional theory (TDDFT) models with the B3LYP functional.

- Highly improved electroluminescence from a series of novel Eu111 complexes with functional single-coordinate phosphine oxide ligands: Tuning the intramolecular energy transfer, morphology, and carrier injection ability of the complexes
-
The functional single-coordinate phosphine oxide ligands (4-diphenylaminophenyl)diphenylphosphine oxide (TAPO), (4-naphthalen-1-yl- phenylaminophenyl)diphenylphosphine oxide (NaDAPO), and 9-[4- (diphenylphosphinoyl)phenyl]-9H-carbazole (CPPO). as the direct combinations of hole-transporting moieties, and electron-transporting triphenylphosphine oxide (TPPO) were designed and synthesized (amines or carbazole), together with their EuIII complexes [Eu(tapo)2(tta)3] (1). [Eu(nadapo):(tta)3] (2), and [Eu(cppo)2(tta)3] (3; TTA: 2-thenoyltrifluoroacetonate). The investigation indicated that by taking advantage of the modification inertia of the phosphine oxide ligands, the direct introduction of the hole-transport groups as chromophore made TAPO, NaDAPO. and CPPO obtain the most compact structure and mezzo Si and T 1 energy levels, which improved the intramolecular energy transfer in their EuIII complexes. The amorphous phase of 1-3 proved the weak intermolecular interaction, which resulted in extraordinarily low self-quenching of the complexes. The excellent double-carrier transport ability of the ligands was studied with Gaussian calculations, and the bipolar structure of TAPO and CPPO was proved. The great improvement of the double-carrier transport ability of 1-3 was shown by cyclic voltammetry. Their HOMO and LUMO energy levels of around 5.3 and 3.0 eV, respectively, are the best results for EuIII complexes reported so far. A single-layer organic light-emitting diode of 2 had the impressive brightness of 59 cd m -2 which, to the best of our knowledge, is the highest reported so far. Both of the four-layer devices based on pure 1 and 2 had a maximum brightness of more than 1000 cdm-2, turn-on voltages lower than 5 V, maximum external quantum yields of more than 3% and excellent spectral stability.
