Research Initiation Award: Polymerization in Metalloporphyrin Metal Organic Frameworks

研究启动奖为历史悠久的黑人学院和大学的初级和职业生涯中期教师提供支持，这些教师正在建立新的研究计划或重新定向和重建现有的研究计划。预计该奖项有助于进一步提高教师的研究能力和有效性，改善所在机构的研究和教学，并让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一个获得化学合成、表征和聚合的基础培训的机会。本研究的目标是开发一种可回收的金属卟啉MOFS(金属-有机骨架)催化剂，通过一种合成流程，利用廉价的原料进行控制选择聚合。这项工作有可能对卟啉与不同金属中心的配位环境有更深入的了解。MOF的形成作为卟啉上基团的函数以及在MOF中的聚合将被研究。并与均相聚合的动力学和机理进行了比较。这项工作有可能发现聚合和MOF回收的理想条件。该工作揭示了MOFS多中心聚合催化剂的多相体系，这将是对传统的单中心聚合均相催化剂的改进。与传统的均相金属卟啉MOF相比，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。更多的进展可能来自利用MOF的高内表面积，使催化聚合效率得以提高。该奖项反映了NSF的法定使命，并通过使用基金会的智力优势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.
