Luminescent materials with red emission are promising materials for optoelectronic devices and biological sciences. However, their synthesis is often complicated. In this work, we developed a facile approach to generating red-emissive luminogens with aggregation-induced emission (AIE) characteristics from commercially available reactants. The new compounds, abbreviated PN-BTZ-Cz and DP-BTZ-Cz, were prepared by coupling 4,7-dibromobenzo[c][1,2,5]thiadiazole with (1-naphehyl)phenylamine or diphenylamine followed by the reaction of the monobromo-substituted compounds with carbazole. Although all of the reactants were non-AIE-active, PN-BTZ-Cz and DP-BTZ-Cz showed AIE characteristics. This suggested that the AIE chromophores were generated in situ through the reactions. PN-BTZ-Cz and DP-BTZ-Cz were soluble in common organic solvents and showed red emission with high fluorescence quantum yields of 42.2 and 38.3% in the film, respectively. They were thermally and morphologically stable, as revealed by their high decomposition temperature (up to 327 C) and glass-transition temperature (up to 120 C). Nondoped organic light-emitting diodes with a configuration of ITO/HATCN/TAPC/PN-BTZ-Cz or DP-BTZ-Cz/Bphen/Liq/Al were fabricated using these compounds as emitting layers, which emitted red electroluminescence at a low turn-on voltage (down to 2.8 V) with a maximum external quantum yield of up to 2.7% and a small efficiency roll-off.

The synthesis of extended heteroarenes via the acid-promoted dehydrocyclisation of arylamino-anthraquinones is examined as an approach to highly conjugated electron-acceptor materials and eventually to heterographene nanoribbons. Whilst the latter perspective is found to remain challenging, the former is exemplified by the synthesis of extended tetraazaheterocycles bearing solubilising alkyl substituents.

Five ligands as monosubstituted derivatives of the basic skeleton of 2,6-bis(2-benzimidazyl)pyridine were synthesized, and characterized by NMR and IR spectra along with the X-ray structure analysis. Their complexation gave a set of hexacoordinate Fe(II) complexes showing predominantly the diamagnetism until ambient temperature. Some temperature-independent paramagnetism along with an onset of the spin transition is also detected.

Tetrameric and octameric 2,6-pyridylene ethynylene oligomers linked to a beta-D-glucopyranoside template through an o-phenylene linker were prepared and studied for their higher-order structure. These oligomers formed chiral helical structures through intramolecular hydrogen bonding between the ethynylpyridine moiety and the glucoside template. The rigidity of the o-phenylene linker stabilizes the helical structure to improve its CD activity and resistance against protic surroundings. Furthermore, the helical stabilization was enhanced by the addition of Cu(OTf)2 and Zn(NO 3)2 salts.

A direct and facile palladium-catalyzed C-H bond oxidative carbonylation reaction and oxidative cyclization for the synthesis of polycyclic aromatic hydrocarbons (PAHs) is reported herein. The intramolecular cyclocarbonylation, through C-H activation and C-C, C-O bond formations under mild conditions, proceeds smoothly with good functional group tolerance in high to excellent yields. The intramolecular palladium-catalyzed direct oxidative C-H bond functionalization for the C-O bond formation is also demonstrated, which provides an efficient approach for the construction of various PAHs.

Two narrow band-gap small molecules with D(A-Ar)2 framework, namely DMPh(DPP-Py)2 and DFPh(DPP-Py)2, were designed and synthesized for high-performance small molecule organic solar cells (SMOSC), in which the 1,4-dimethoxybenzene (DMPh) and 1,4-difluorobenzene (DFPh) were employed as rigid donor cores, respectively, and the pyrenere (Py) unit is selected as terminal-capping groups on an electron-deficient diketopyrrolopyrrole (DPP)-based linear backbone. The impacts of the fluorine-sulfur (F?S) atoms and oxygen-sulfur (O?S) atoms noncovalent interaction on their absorption spectra, molecular energy levels, morphological properties, hole mobilities and photovoltaic properties were investigated thoroughly. The fluorinated DFPh(DPP-Py)2 possess a relatively lower-lying HOMO energy level, better miscibility of the blend with PC71BM, as well as higher mobility in comparison with those of the methoxyled DMPh(DPP-Py)2. As a consequence, the OSCs devices based on DMPh(DPP-Py)2 and DFPh(DPP-Py)2 exhibited PCEs of 5.47% and 7.54%, respectively. Obviously, the device based on DFPh(DPP-Py)2 presented a better performance, which should be ascribed to the improved simultaneously Voc of 0.77 V, Jsc of 15.3 mA cm?2, and FF of 64%. The results indicated that the choice of the fluorination designation on the molecular backbone is an effective approach to develop D(A-Ar)2 type small molecule donors for highly efficient solar cell applications.

Mixtures of Pd(dba)2 + 2L-L (where L-L is a bidentate ligand such as dppm, dppe, dppp, dppb, dppf, and DIOP) lead to the formation of Pd(L-L)2 complexes which do not undergo an oxidative addition with phenyl iodide. Mixtures of Pd(dba)2 + 2 BINAP do not afford Pd(BINAP)2 but Pd(dba)(BINAP). Mixtures of Pd(dba)2 + IL-L (L-L = dppm, dppe, dppp, dppb, dppf, DIOP, and BINAP) lead to Pd(dba)(L-L) complexes via the formation, at short time, of the complex Pd(L-L)2, except for dppf and BINAP where the complex Pd(dba)(L- L) is directly formed. Pd(dba)(L-L) is the main complex in solution but is involved in an endergonic equilibrium with the less ligated complex Pd(L-L) and dba. Pd(L-L) is the more reactive species in the oxidative addition with phenyl iodide. However, Pd(dba)(L-L) also reacts in parallel with phenyl iodide. From the kinetic data concerning the reactivity of these different catalytic systems in the oxidative addition with phenyl iodide, one observes the following order of reactivity: Pd(dba)2 + 1DIOP > Pd(dba)2 + 1dppf >> Pd(dba)2 + 1BINAP. All these systems associated to one bidentate ligand are less reactive than Pd(dba)2 + 2PPh3.
