- Balancing Mechanical Stability and Ultrahigh Porosity in Crystalline Framework Materials
-
A new mesoporous metal–organic framework (MOF; DUT-60) was conceptually designed in silico using Zn4O6+ nodes, ditopic and tritopic linkers to explore the stability limits of framework architectures with ultrahigh porosity. The robus

- Structures of branched oligophenylenes studied by NMR spectroscopy
-
A series of model cyclotrimers was studied by NMR spectroscopy using 2D COSY, HSQC, and HMBC correlations to establish the structures of branched oligophenylenes, whose branch-ing center is the 1,3,5-triphenyl-substituted benzene ring.

- Highly efficient synthesis of substituted benzenes in the presence of B(HSO4)3 as a new and reusable catalyst under solvent-free conditions
-
A highly efficient and simple procedure for the synthesis of substituted benzenes is described. A broad range of ketones (alkyl-aryl ketones and cyclic ketones) were condensed via a cyclotrimerization reaction in the presence of catalytic amounts of boron sulfonic acid [B(HSO4)3], a new, highly efficient, and reusable catalyst, under solvent-free conditions. All reactions completed in short times without formation of any by-products. The catalyst was recovered and reused successfully for 15 cycles of the reaction. Copyright

- Reusable resin Amberlyst 15 catalyzed new convenient protocol for accessing arylated benzene scaffolds
-
Polyarylated benzene derivatives are useful molecular entities in chemical and material sciences owing to their unique photophysical properties associated with them. In this Letter, we report that 2-acetyl-benzofuran in the presence of Amberlyst 15 at reflux temperature furnished a mixture of dimer, trimer, and tetramer with interesting conformational properties. The protocol was generalized to prepare diverse arylated benzene scaffolds in good yields under similar reaction conditions.

- Pure Deep Blue Light-Emitting Diodes from Alternating Fluorene/Carbazole Copolymers by Using Suitable Hole-Blocking Materials
-
The influences of the carbazole content on the photophysical, electrochemical, and electroluminescent properties of alternating fluorene/carbazole copolymers PFnCz (n = 1, 2, 3) with well-defined chemical structures have been systematically investigated. The incorporation of carbazole units into the polyfluorene (PF) backbone resulted in a blue shift of both the absorption and photoluminescence (PL) emission peaks, improved PL thermal stability, raised HOMO energy levels, and thus facilitated hole injection into the copolymers. Pure deep blue electroluminescence (EL) with narrow with (full width at the half-maximum) (39-52 nm) and negligible low-energy emission bands was successfully achieved from the PFnCz copolymers by using l,3,5-tris(4′-fluorobiphenyl-4-yl)benzene (F-TBB) as a hole-blocking layer and Alq3 as an electron injection/transporting layer. This device configuration stabilized the blue emission from the PF derivatives. An efficiency of 0.72 cd/A at a luminance of 100 cd/m2 was obtained even with aluminum metal as the cathode.
