Research Initiation Award: Polymerization in Metalloporphyrin Metal Organic Frameworks

研究启动奖为传统黑人学院和大学的初级和中期职业教师提供支持，他们正在建立新的研究项目或重新指导和重建现有的研究项目。期望该奖项有助于提高教师的研究能力和效率，改善所在机构的研究和教学，并使本科生参与研究经验。该奖项授予休斯顿蒂洛森大学，提出了一种使用金属化合物的新合成方案。这些化合物的合成和表征将为本科生提供在化学合成、表征和聚合方面获得基本训练的机会。本研究的目标是开发一种可回收的金属卟啉mfs（金属有机框架）催化剂，通过合成流程利用廉价的起始材料进行可控的选择性聚合。这项工作有可能使人们对卟啉与不同金属中心的配位环境有更深入的了解。研究了卟啉基团对mof形成的影响以及mof内部的聚合反应。将其动力学和机理与均相聚合进行比较。这项工作有可能发现聚合和mof回收的理想条件。这项工作将揭示一个多相体系的mof催化剂的多位点聚合，这将是传统的单位点聚合的均相催化剂的改进。与传统的均相mof相比，所提出的金属卟啉mof具有提高催化剂稳定性和可回收性的优点。利用mof的高内表面积可以进一步提高催化聚合的效率。该奖项反映了美国国家科学基金会的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。

Research Initiation Awards provide support for junior and mid-career faculty at Historically Black Colleges and Universities who are building new research programs or redirecting and rebuilding existing research programs. It is expected that the award helps to further the faculty member's research capability and effectiveness, improve research and teaching at the home institution, and involves undergraduate students in research experiences. The award to Huston-Tillotson University proposes a new synthetic scheme using metal compounds. The synthesis and characterization of these compounds will provide an opportunity for undergraduate students to obtain basic training in chemical synthesis, characterization, and polymerization. The goal of the proposed study is to develop a recyclable metalloporphyrin MOFs (metal-organic frameworks) catalyst by means of a synthesis flow utilizing inexpensive starting materials for controlled selective polymerization. The work has the potential to yield a deeper understanding about the coordination environment of porphyrin with different metal centers. The MOFs formation as a function of groups on the porphyrin and polymerization inside the MOFs will be studied. The kinetics and mechanism will be compared with those in homogenous polymerization. The work has the potential to discover ideal conditions for polymerization and MOFs recovery. The work could uncover a heterogenous system of MOFs catalyst of multiple-site polymerization which would be an improvement over traditional homogenous catalysts of single-site polymerization. The proposed metalloporphyrin MOFs could have the benefits of increased catalyst stability and recyclability in contrast to traditional homogeneous ones. Additional advances could come from utilizing the high internal surface area of MOFs, enabling advances in the efficiency of catalytic polymerization.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
