Functionalized Nanoporous Membranes

这个无机、生物无机和有机金属化学项目的奖项是NSF 98-20纳米技术计划的一部分，支持西北大学约瑟夫·t·赫普博士实验室的研究。该研究将涉及基于由吡啶衍生物或吡啶功能化卟啉连接的面状三羰基铼基团的纳米通道膜的制造。具体研究课题包括：基于纳米通道尺寸的超滤或基于吡啶-烷基硫醇功能化空腔氧化/还原的调制超滤；利用功能化客体配体修饰纳米通道内部的亲和膜分离；手性金属卟啉纳米通道包封膜催化反应器的研究以及通过纳米孔的吸附和运输模型。纳米多孔分子材料在化学分离过程中具有很高的选择性和效率。这些新材料可能在制药、特种化工、半导体和石油化工等行业有应用。

This award in the Inorganic, Bioinorganic and Organometallic Chemistry Program is part of the NSF 98-20 Nanotechnology initiative and supports research in the laboratories of Dr. Joseph T. Hupp at Northwestern University. The research to be performed involves the fabrication of nanochannel membranes based upon facial-tricarbonyl rhenium moieties linked by pyridine derivatives or pyridine functionalized porphyrins. Specific topics to be studied include: ultrafiltration based upon nanochannel size or modulated ultrafiltration based upon oxidation/reduction of pyridine-alkylthiol functionalized cavities; affinity membrane separation that utilizes functionalized guest ligands to modify the interior of nanochannels; membrane catalytic reactors that are constructed by the encapsulation of chiral metalloporphyrins in nanochannels; and transport modeling of adsorption and transport through nanopores. Nanoporous molecular materials are expected to achieve very high selectivity and efficiency in chemical separation processes. These new materials may have applications in the pharmaceutical, specialty chemical, semiconductor, and petrochemical industries.
