Complex Functional Materials Accessed through Precision Scaffold Synthesis

该研究项目能够合成具有精确构建块序列的下一代功能性聚合物（塑料）。精确的合成顺序允许大量制备聚合物，这些数量使研究人员能够确定合成序列对新聚合物物理性质的影响。这些合成方法很容易被聚合物界采用，因为这些材料是由市售的简单起始材料一步制备的。本项目培养研究生从事解决化学-材料-化学工程界面问题的界面研究项目。在石溪大学（Stony Brook University）阿尔达传播科学中心（Alda Center for communication Science）的主持下，通过对一般公众传播的正式培训，将研究的影响转移到更广泛的社区。研究人员利用技术来提高受众的参与度，提炼他们的信息，让当地的高中生和大学生参与到这项研究的活动中来。本项目的重点是开发交替开环复分解聚合合成，为材料提供单体水平的序列控制。随着钌催化剂开发的成功，提供了官能团耐受性和快速增殖的催化剂，下一个目标是开发单体，产生具有以前无法达到的纳米级形态的材料。Sampson实验室最近发现的双环[4.2.0]oct-1(8)-ene-8-carboxamide-/环己烯体系允许制备非常长的交替聚合物，具有很高的单体经济性。计划对交替聚合物反应的范围进行积极的测定。这个项目确定聚合物微观结构可以和不能实现。化学研究为探索和发现由于精确的大分子序列控制而形成的新型纳米级结构提供了独特的机会。

This research project enables the synthesis of next generation functional polymers (plastics) with precise sequences of building blocks. The precise sequence of the synthesis allows preparation of the polymers in bulk quantities and these quantities enable the researchers to determine the effects of the synthetic sequences on the physical properties of the new polymers. These synthetic methods are readily adoptable by the polymer community because the materials are prepared in one-step from simple starting materials that are commercially available. This project trains graduate students to pursue interfacial research projects that solve problems at the chemistry-materials-chemical engineering interface. The research impact is transferred to the broader community through formal training in general public communication under the auspices of the Alda Center for Communicating Science at Stony Brook University. Using techniques to improve audience engagement and for distilling their message, researchers engage local high school students and college students in understanding the activities of this research.This project is centered on developing alternating ring-opening metathesis polymerization syntheses that provide materials with monomer-level control of sequence. With the successes in ruthenium catalyst development provide both functional group tolerant and rapidly propagating catalysts, the next goal is to develop monomers that generate materials with previously inaccessible types of nanoscale morphologies. The Sampson laboratory's recent discovery of the bicyclo[4.2.0]oct-1(8)-ene-8-carboxamide-/cyclohexene system allows the preparation of very long, alternating polymers with high monomer economy. An aggressive determination of the scope of the alternating polymer reaction is planned. This project identifies polymer microstructures that can and cannot be achieved. The chemistry research provides a unique opportunity to explore and discover novel nanoscale structures formed as a consequence of precise macromolecular sequence control.
