从反应条件看有机反应在POPs合成中的应用

多孔有机聚合物(POPs)是一种完全通过有机共价连接的具有良好的热、化学稳定性以及高的比表面积和永久空隙率的化合物,在气体储存、吸附分离、均相催化、光电材料等领域潜具有潜在的应用前景。将基础有机反应拓展到POPs的合成,不仅可以通过多样的、可调节的合成方法赋予POPs优异的性能,而且极大地促进了POPs的发展,使之成为继沸石、MOFs等之后研究的一大热点。由于POPs具有高的分子量和交联度,合成单体具有大的立体空间结构产生的空间位阻等特点,要求合成条件更为苛刻。Suzuki及Friedel-Crafts烷基化反应作为合成POPs重要的合成方法,本文系统地介绍了这两种方法的历史、反应体系以及近几年在POPs合成中的最新研究进展,希望从合成体系的角度为POPs的设计、合成提供一定的借鉴。     

Synthesis and Characterization of [NH3（CH2）2NH2（CH2）2NH3]BiCl6

1 INTRODUCTION During the past decade, a series of organic-inor- ganic hybrid compounds based on metal halide units have been prepared and studied[1]. The combination of organic and inorganic components at the mole- cular level affords us the opportunity to design new hybrid materials and modulate the properties of components[2]. As a result, some interesting proper- ties, such as non-linear optical[3], interesting magne- tic[4], efficient luminescence[2], ideal thermal and mechanical sta…     

Carbazole Based Anionic MOF for Proton Conductivity

A non-interpenetrated anionic In-MOF(FJU-302)based on a linear H2 bpdc and an angled H2 cdc as dual-ligands was characterized by FT-IR,TGA and X-ray single-crystal/powder diffraction.FJU-302 crystallizes in the monoclinic system and I4₁/amd space group with a=27.1274(8),b=27.1274(8),c=29.788(3)?,V=21921(2)?³,Z=16,M_r=608.32,D_c=0.737 g/cm³,F(000)=4848,μ(Cu Kα)=3.659 mm^–1,R=0.0800 and wR=0.1911 for 5703 observed reflections(I>2s(I)),and R=0.1470 and w R=0.2342 for all data.In this work,a carbazole based anionic In-MOF(FJU-302)was designed and synthesized,and the proton conductivity from subzero temperature(–30℃)to 70℃ was measured without additional humidity.FJU-302 presents a max proton conductivity of 6.47×10^–4 S·cm^–1 at 70℃,and it can maintain 5.88×10^–7 S·cm^–1 at–30℃.This work reports a first carbazole based MOF for proton conductivity at subzero temperature conditions.
