With the increasing demand for synthetic rubber,the purification of 1,3-butadiene(C_(4)H_(6))is of great industrial ***,the successful removal of n-butene(n-C_(4)H_(8))and iso-butene(iso-C_(4)H_(8))from 1,3-butadiene(C_(4)H_(6))was realized by synthesizing a novel TaOF_(5)^(2-) anion-pillared ultramicroporous material TaOFFIVE-3-Ni(also referred to as ZU-96,TaOFFIVE=TaOF_(5)^(2-),3=pyrazine).Single-component adsorption isotherms show that TaOFFIVE-3-Ni can achieve the exclusion of n-C_(4)H_(8) and iso-C_(4)H_(8) in the low pressure region(0–30 kPa),and uptake C_(4)H_(6) with a high capacity of 92.78 cm^(3)·cm^(-3)(298 K and 100 kPa).The uptake ratio of C_(4)H_(6)/iso-C_(4)H_(8) on TaOFFIVE-3-Ni was 20.83(298 K and 100 kPa),which was the highest among the state-of-the-art adsorbents reported so *** the rotation of anion and pyrazine ring,the pore size changes continuously,which makes smaller-size C_(4)H_(6) enter the channel while larger-size n-C_(4)H_(8) and iso-C_(4)H_(8) are completely *** excellent breakthrough performance of TaOFFIVE-3-Ni shows great potential in industrial separation of C4 *** specific adsorption binding sites within ZU-96 was further revealed through the modeling calculation.

Trans-/cis-olefin isomers play a vital role in the petrochemical *** paucity of energy-efficient technologies for their splitting is mainly due to the similarities of their physicochemical ***,two new tailor-made anion-pillared ultramicroporous metal–organic frameworks(MOFs),ZU-36-Ni and ZU-36-Fe(GeFSIX-3-Ni and GeFSIX-3-Fe)are reported for the first time for the efficient trans-/cis-2-butene(trans-/cis-C_(4)H_(8))mixture splitting by enhanced molecular ***,ZU-36-Ni unexpectedly exhibited smart guest-adaptive pore channels for trapping trans-C_(4)H_(8)with a remarkable adsorption capacity(2.45 mmol∙g^(−1))while effectively rejecting cis-C_(4)H_(8)with a high purity of 99.99%.The dispersion-corrected density functional theory(DFT-D)calculation suggested that the guest-adaptive behavior of ZU-36-Ni in response to trans-C_(4)H_(8)is derived from the organic linker rotation and the optimal pore dimensions,which not only improve the favorable adsorption/diffusion of trans-C_(4)H_(8)with optimal host–guest interactions,but also enhance the size-exclusion of cis-C_(4)H_(8).This work opens a new avenue for pore engineering in advanced smart or adaptive porous materials for specific applications involving guest molecular recognition.

光致热弹光谱(LITES)技术是近年来发展迅速的一种新颖痕量气体检测技术,该技术以体积小巧、成本低廉且无波长选择性的音叉式石英晶振替代成本高、探测波段窄的光电探测器作为光电换能器,通过探测激光与目标气体相互作用后光强的变化量实现目标气体浓度的反演。LITES技术具有探测灵敏度高、响应时间短、无波长选择性等优点。本文以下水道中的硫化氢气体为测量目标,开展了基于LITES技术的痕量气体探测系统的研究。以输出波长为1.582μm的近红外连续波分布反馈单纵模二极管激光器作为激发光源,采用激光器波长调制和二次谐波探测技术,首先研究了激光波长调制深度对LITES系统产生的信号幅度的影响,而后详细研究了气体压强及环境压强对装置性能的影响。此外,为进一步提升装置探测灵敏度,有效光程长度为14.5 m的Herriott多通池被装配在激光器和作为光电探测器的音叉式石英晶振之间,从而使传感器在积分时间为300 ms时,获得4.87×10^(-7)的最低探测极限,当积分时间延长至52 s时其探测灵敏度可达7.78×10^(-8)。在完成装置各项参数优化之后开展了下水道中硫化氢气体的实测研究,结果显示,该系统完全可满足下水道臭气监测分析等领域的应用需求。
