Synthesis of 2D MOFs is often sensitive to the reaction conditions like temperature and solvent etc. Cu(II)-5-azidoisophthalate MOF (Cu(II)–5N3IP) has been synthesized at room temperature as well as under solvothermal conditions. The azide functional group remained stable during solvothermal synthesis at 85 °C. Cu(II)–5N3IP crystallized in a Kagomé-type structure. Typical Cu2 paddle-wheels are connected to each other by 5N3IP ligands in infinite 2D sheets in the (001) plane, featuring 1D infinite channels within each layer. This MOF is used for the adsorption of methylene blue (MB), rhodamine B (RhB), methyl orange (MO), and Congo red (CR). The adsorption is selective to the dimensions, shapes and ionic strengths of the dyes. Cu(II)–5N3IP exhibited adsorption rates in the order MB > CR > RhB > MO. Cu(II)–5N3IP is used as a catalyst for aerobic oxidation and Knoevenagel condensation. 3–10 mol% of Cu–5N3IP selectively catalyzes the oxidation of benzyl alcohol to benzaldehyde in 9–20 h at 60 °C. In Knoevenagel condensation, the reaction of both unsubstituted and substituted benzaldehydes at room temperature was observed at a very low catalyst loading of 3 mol% of MOF within a short time of 3–60 min. This 2D MOF has proved to be more efficient for dye adsorption and the catalytic applications under investigation (such as alcohol oxidation and Knoevenagel condensation) than its analogous 3D or 0D materials.

二维MOF的合成具有高效染料吸附和催化应用的潜力†
二维MOF的合成通常对诸如温度和溶剂等反应条件敏感。Cu（II）-5-叠氮间苯二甲酸Cu（II）-5-MOF（Cu（II）–5N 3 IP）在室温以及溶剂热条件下均已合成。在溶剂热合成过程中，叠氮化物官能团在85°C时保持稳定。Cu（II）–5N 3 IP以Kagomé型结构结晶。典型的Cu 2桨轮通过5N 3相互连接（001）平面中无限2D片中的IP配体，每层内均具有1D无限通道。该MOF用于吸附亚甲基蓝（MB），若丹明B（RhB），甲基橙（MO）和刚果红（CR）。吸附对染料的尺寸，形状和离子强度具有选择性。Cu（II）–5N 3 IP表现出的吸附速率为MB> CR> RhB> MO。Cu（II）–5N 3 IP被用作好氧氧化和Knoevenagel缩合的催化剂。3-10 mol％的Cu-5N 3IP在60°C下9–20小时内选择性催化苄醇氧化为苯甲醛。在Knoevenagel缩合反应中，在3-60％的短时间内，以3 mol％的MOF的非常低的催化剂负载量，在室温下观察到未取代和取代的苯甲醛的反应。这种2D MOF已证明比其类似的3D或0D材料在染料吸附和所研究的催化应用（如醇氧化和Knoevenagel缩合反应）方面更为有效。
