A flexible metal-organic framework of 1a Cu(FMA)(4,4'-Bpe)0.5(FMA=fumarate; 4,4'-Bpe=trans-bis-(4-pyridyl)ethylene) that exhibits guest molecule-controlled gate-opening adsorption has been reported, in which the flexible pores can be enlarged by CO_2 molecules rather than CH_4 and N_2 under a certain gate-opening pressure. The CO_2 uptake can be sharply improved from 6.85cm^3 g^(–1) at 0.60 atm to 33.7 cm^3 g^(–1) at 1 atm due to the gate-opening effect, thus resulting in the notably enhanced adsorption selectivities for CO_2/CH_4(32:1, v/v) and CO_2/N_2(48:1, v/v) separations at room temperature.

为探索斜爆轰波诱导区特性变化的内在机制,利用带H2/O2详细化学反应模型的二维欧拉方程进行数值模拟,研究了当量比对诱导区特性的影响。结果表明,随着当量比增大,诱导区长度呈U型曲线变化,在此过程中温度起到了关键作用。通过研究诱导区末端的压力分布发现,诱导区末端的压缩波强度是影响诱导区过渡形式的决定性因素。当量比在0.6～2.5时,压缩波强度较强,过渡形式为突变型,超出该范围,压缩波强度较弱,过渡形式为平滑型。此外,结合定容燃烧(CVC)理论分析了不同来流压力下的诱导区长度随当量比的变化情况,得出诱导区内的化学动力学效应影响了诱导区长度,使其沿理论所预测的U型曲线变化;气动力学效应影响了诱导区长度的变化幅度和速率,避免其过度增大或减小。

甘油是产量巨大的生物质.将之转化为有用化合物的研究,有重要的工业应用价值.甘油的氢解可生成一系列的C-3醇,如正丙醇、异丙醇、1,2-丙二醇以及1,3-丙二醇等.其中,1,3-丙二醇是合成聚对苯二甲酸丙二醇酯(PPT)的重要有机中间体.因此,选择性氢解甘油合成1,3-丙二醇,是一个重要的研究课题.最近,在研究Pt/WO_3/Zr O_2催化下的甘油氢解反应时发现,通过调控催化剂载体中氧化钨含量,可以调节催化剂的酸碱度,从而在保持较高1,3-丙二醇选择性的同时,显著提高反应的转化率.这一技术提高了合成效率,有潜在的工业应用价值.

对三苯胺进行溴代和C-N偶联反应合成4-萘基三苯胺(a),对脱氢枞酸进行酯化、溴代、硝化、还原和C-N偶联反应合成13-[N,N-(4-萘基苯基)-苯基]胺基-脱异丙基脱氢枞酸甲酯(b)及13-[N,N-双(4-萘基苯基)]胺基-脱异丙基脱氢枞酸甲酯(c)两个化合物,通过1HMNR,13CMNR及MS对化合物的结构进行表征。为了研究化合物结构与光谱性能之间的关系,首先利用Gaussian09程序采用密度泛函DFT/B3LYP方法,对三个化合物的空间构型进行全优化,得到它们的键长、键角和二面角,对比发现脱氢枞酸骨架和萘环的引入会影响化合物的共平面性,而萘环的引入会增大化合物的共轭程度。光谱性能方面,研究了三种化合物在甲醇、二氧六环、四氢呋喃、二氯甲烷和环己烷这5种极性逐渐减小的溶剂中的荧光发射光谱和紫外吸收光谱。结果表明,在荧光光谱中,化合物a,b和c在不同极性溶剂中最大荧光发射波长均有不同程度位移,在甲醇中最大,在环己烷中最小,但是位移并非随着极性的增大而只发生红移,在二氯甲烷、四氢呋喃和二氧六环3种极性依次增大的溶剂中,a,b,c的荧光发射波长均随着溶剂极性的增大而发生较大程度的蓝移;在同一溶剂中,化合物b和c相对于a的荧光发射波长依次发生红移,c的红移程度与b差距不大。紫外吸收光谱中,三个化合物在不同极性溶剂中的最大吸收波长也有差异,在200~250nm区间,三个化合物均在二氯甲烷中有较大位移,在300~350nm区间,在甲醇中位移较大,而在250~300nm区间,最大吸收波长差别不大;在同一溶剂中,它们在300~350nm区间的最大吸收波长差别较大,化合物c较a红移26nm。结合结构优化所得数据可以证明,化合物的共轭程度对荧光发射光谱和紫外吸收光谱均有影响,而共平面性对荧光发射光谱影响较大。化合物a,b和c在不同极性溶剂中荧光发射光谱和紫外吸收光谱的较大变化,表明它们有明显的溶致变色行为,具有作为分子探针探测外部环境极性大小的潜能。
