  A convenient and general method for the preparation of sixteen 3,5-diarylsubstituted 2,4- and 2,6-dimethylpyridines of high forensic importance is described. The Suzuki cross-coupling reaction between a range of ring-substituted phenylboronic acids and 3,5-dibromo-2,4-dimethylpyridine and 3,5-dibromo-2,6-dimethylpyridine was used as a key step.

• Three isoreticular ssa-type MOFs derived from bent diisophthalate ligands: exploring the substituent effect on structural stabilities and selective C₂H₂/CH₄ and CO₂/CH₄ adsorption properties

  日期：——

  the effect of the substituents on structural stabilities and gas adsorption properties of MOFs is fundamentally important for rational design and synthesis of new MOFs with better performance. For this purpose, three isoreticular copper-based MOFs (ZJNU-87, ZJNU-88 and ZJNU-89) with ssa-type topology were successfully constructed from bent diisophthalate ligands bearing different substituents. Permanent

  评估取代基对MOF的结构稳定性和气体吸附性能的影响，对于合理设计和合成性能更好的新型MOF至关重要。为此，成功地从带有不同取代基的二间苯二酚弯曲配体上构建了三个具有ssa型拓扑结构的等网状铜基MOF（ZJNU -87，ZJNU-88和ZJNU-89）。永久孔隙率研究表明，取代基对骨架抗去溶剂化的稳定性有重大影响。利用非极性Ñ己烷作为激活溶剂可提供更多的优化的永久多孔性非极性或较小极性取代基改性的浙江师范大学-88和浙江师范大学-89。此外，系统地研究了它们对C 2 H 2，CO 2和CH 4的气体吸附性能，揭示了它们有选择性分离C 2 H 2 / CH 4和CO 2 / CH 4的潜力。特别地，就吸收容量和吸附选择性而言，甲氧基改性的ZJNU-89的性能优于甲基改性的ZJNU-88，这可能归因于ZJNU-89的更合适的孔空间。
