  Reusable Amine-Based Structural Motifs for Green House Gas (CO₂) Fixation

  摘要：

  A series of compounds with an amine based structural motif (ASM) have been synthesized for efficient atmospheric CO2 fixation. The H-bonded ASM bicarbonate complexes were formed with an in situ generated HCO3- ion. The complexes have been characterized by IR, C-13 NMR, and X-ray single-crystal structural analysis. ASM bicarbonate salts have been converted to pure ASMs in quantitative yield under mild conditions for recycling processes.

• Reduced Schiff-base assisted novel dihydrogenphosphate–water polymer

  Reduced Schiff bases with a common p-nitro-o-phenylenediamine moiety have been synthesised and their structures have been characterized by single-crystal structural analysis. Schiff bases having self-complementary H-bond donors and H-bond acceptors can form a “scissors” like structure through intermolecular H-bonding interaction. Reduced Schiff bases interact with biologically important dihydrogenphosphate ion and form stable complexes. Furthermore, dihydrogenphosphate and water form an unprecedented self-assembled dihydrogenphosphate–water [H2PO4·H2O]nn− 1D supramolecular polymer upon complexation with reduced Schiff bases.

  合成了具有共通p-硝基-o-苯二胺基团的还原施夫碱，并通过单晶结构分析对其结构进行了表征。具有自互补氢键供体和氢键受体的施夫碱可以通过分子间氢键相互作用形成“剪刀”状结构。还原施夫碱与生物学上重要的二氢磷酸根离子相互作用，形成稳定的复合物。此外，二氢磷酸根和水在与还原施夫碱络合时形成前所未见的自组装二氢磷酸根-水 [H2PO4·H2O]nn⁻ 1D 超分子聚合物。

  Lock up your valuables: Receptor 1 acts as a “molecular lock” and anions act as “keys”; H2PO4− can “lock” 1 by switching it from its “unlocked” conformation, however, the structurally similar HSO4− cannot “lock” receptor 1 as evidenced by single‐crystal X‐ray analysis (see scheme). The “unlocked–locked” conformational switching of 1 was investigated by monitoring changes in fluorescence intensity in

  锁上贵重物品：受体1充当“分子锁”，而阴离子充当“钥匙”；ħ 2 PO 4 -可以“锁定” 1通过从它的“解锁”构象切换它，但是，结构类似的HSO 4 -不能“锁”受体1如由单晶X射线分析（参见方案）。通过在存在不同阴离子的情况下监测荧光强度的变化，研究了1的“开锁”构象转换。
