Complex Functional Materials Accessed through Precision Scaffold Synthesis

这项研究项目使合成具有精确构建块序列的下一代功能聚合物(塑料)成为可能。精确的合成顺序允许大量制备聚合物，这些量使研究人员能够确定合成顺序对新聚合物物理性能的影响。这些合成方法很容易被聚合物社区采用，因为这些材料是从商业上可获得的简单起始材料一步制备而成的。这个项目培养研究生从事界面研究项目，解决化学-材料-化学工程界面上的问题。在石溪大学阿尔达传播科学中心的主持下，通过一般公共传播方面的正式培训，研究的影响被转移到更广泛的社区。研究人员使用技术来提高观众的参与度并提取他们的信息，让当地的高中生和大学生参与到这项研究的活动中来。这个项目的中心是开发交替的开环歧化聚合合成，提供具有单体水平的序列控制的材料。随着Ru催化剂开发的成功提供了官能团耐受和快速繁殖的催化剂，下一个目标是开发能够产生以前无法获得的纳米级形貌的材料的单体。桑普森实验室最近发现的bicyclo[4.2.0]oct-1(8)-ene-8-carboxamide-/cyclohexene系统使人们能够制备具有高单体经济性的超长交替聚合物。计划对交替聚合物反应的范围进行积极的确定。该项目确定了可以实现和不能实现的聚合物微结构。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的纳米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.
