  摘要：

  Acyclic o-phenylene-bridged bis(anilido-aldimine) compounds, o-C6H4{C6H2R2N=CH-C6H4(H)N(C6H3R'(2))}(2) and related 30-membered macrocyclic compounds, o-C6H4{C6H2R'N-2=CH-C6H4-(H)-N(C6H2R2}(2) (o-C6H4) are prepared. Successive additions of Me2Zn and SO2 gas to the bis(anilido-aidimine) compounds afford quantitatively dinuclear mu-methylsulfinato zinc complexes, o-C6H4{(C6H2R2N=CH-C6H4N(C6H3R'(2))-kappa(2)-N,N)Zn(mu-OS(O)Me)(2) (R = iPr and R' = Pr, 29; R = Et and R' = Et, 30; R = Me and R' = Me, 31; R = Me and R' = Pr, 32; R = Et and R' = Me, 33; R = Et and R' = Pr, 34; R = Pr and R' = Et, 35) and o-C6H4{C6H2R'N-2=CH-C6H4-N-C6H2R2-kappa(2)-N,N)Zn(mu-OS(O)Me)}(2) (o-C6H4) (R Et and R' = Et, 36; R = Me and R' = Me, 37; R = Pr and R' = Me, 38; R = Et and R' = Me, 39; R Me and R' = Pr, 40). Molecular structures of 34 and 40 are confirmed by X-ray crystallography. Complexes 30-35 show high activity for cyclohexene oxide/CO2 copolymerization at low [Zn]/[monomer] ratio (1:5600), whereas the complex of mononucleating beta-diketiminate {[(C6H3Et2)N=C(Me)CH=C(Me)N(C6H3Et2)]Zn(mu-OS(O)Et}(2) shows negligible activity in the same condition. Activity is sensitive to the N-aryl ortho substituents and the highest activity is observed with 32. Turnover number up to 2980 and molecular weight (M-n) up to 284 000 are attained with 32 at such a highly diluted condition as [Zn]/[monomer] = 1: 17 400. Macrocyclic complexes 36-40 show negligible activity for copolymerization.

  Layer stacking and chemical stability are crucial for two-dimensional covalent organic frameworks (2D COFs), but are yet challenging to gain control. In this work, we demonstrate synthetic control of both the layer stacking and chemical stability of 2D COFs by managing interlayer steric hindrance via a multivariate (MTV) approach. By co-condensation of triamines with and without alkyl substituents

  层堆叠和化学稳定性对于二维共价有机框架 (2D COF) 至关重要，但仍难以获得控制。在这项工作中，我们通过多变量 (MTV) 方法管理层间位阻，展示了对 2D COF 的层堆叠和化学稳定性的综合控制。通过具有和不具有烷基取代基（乙基和异丙基）和二醛或三醛的三胺的共缩合，制备了具有 AA、AB 或 ABC 堆积的二元、三元和四元 2D COF 家族。烷基周期性地附加在通道壁及其内容上，可以通过 MTV 策略进行综合调整，通过最大化总晶体堆积能和通过动力学阻断保护水解敏感骨架来控制二维 COF 的堆积模型和化学稳定性。具体而言，具有较高烷基取代基浓度的 COF 采用 AB 或 ABC 堆积，而较少量的官能团导致 AA 堆积。带有高浓度异丙基的 COF 代表了第一个确定的可以在沸腾的 20 M NaOH 溶液中保持结晶度和孔隙率的 COF。在用铱络合物合成后金属化后，2,2'-联吡啶衍生的 COF
