  Engineering Hydrogen-Bonded Molecular Crystals Built from Derivatives of Hexaphenylbenzene and Related Compounds

  摘要：

  Hexakis[4-(2,4-diamino-1,3,5-triazin-6-yl)phenyl]benzene (4) incorporates a disc-shaped hexaphenylbenzene core and six peripheral diaminotriazine groups that can engage in hydrogen bonding according to established motifs. Under all conditions examined, compound 4 crystallizes as planned to give closely related noninterpenetrated three-dimensional networks built from sheets in which each molecule has six hydrogen-bonded neighbors. In the structure of compound 4, the number of hydrogen bonds per molecule and the percentage of volume accessible to guests approach the highest values so far observed in molecular networks. Analogue 5 (which has the same hexaphenylbenzene core but only four diaminotriazine groups at the 1,2,4,5-positions) and analogue 7 (in which the two unsubstituted phenyl groups of compound 5 are replaced by methyl groups) crystallize according to a closely similar pattern. Analogues with flatter pentaphenylbenzene or tetraphenylbenzene cores crystallize differently, underscoring the importance of maintaining a consistent molecular shape in attempts to engineer crystals with predetermined properties.

  The synthesis of five novel distyrylbenzene (DSB) derivatives, featuring a central tetraphenylbenzene core, is reported. The targets show aggregation‐induced emission (AIE), which, however, is substituent‐dependent. For the pure hydrocarbon and derivatives that do not carry (+M) or (−M) substituents, classic AIE behavior is observed, that is, the DSBs are non‐fluorescent in solution, but are highly

  报道了以中央四苯基苯核为特征的五种新型二苯乙烯基苯（DSB）衍生物的合成。目标显示聚集诱导发射（AIE），但是，它是取代基依赖性的。对于不带有（+ M）或（-M）取代基的纯烃及其衍生物，观察到经典的AIE行为，即DSB在溶液中无荧光，但在形成聚集体时在冷基质中具有高荧光在不良溶剂中呈固态结晶状态。如果在对位上连接有醛基或二丁基氨基DSB单元的位置，将生成非经典的AIE phores。它们在稀溶液和固态中均发荧光。靶的长时间照射通过双环化产生苯并四苯衍生物。

  Through combining the supermolecular building layer (SBL) approach for designing MOFs with the liquid phase epitaxy growth method, we demonstrate that it is possible to precisely control the epitaxial growth of MOF-on-MOF thin films, for ordered hierarchical tbo-type structures.

  areas of 3971 m(2) g(-1) and 2363 m(2) cm(-3) represent an increase of 115% and 47%, respectively, in comparison to the corresponding values for the prototypical HKUST-1 (tbo-MOF-1), and are 42% and 20% higher than that of tbo-MOF-2. High-pressure methane adsorption isotherms revealed a high total gravimetric and volumetric CH4 uptakes, reaching 372 cm(3) (STP) g(-1) and 221 cm(3) (STP) cm(-3), respectively
