PART 1: NON-TECHNICAL SUMMARYPolymers that have a ladder-like, double-stranded, and ribbon-like molecular chain architecture are termed ladder polymers. They have been the object of scientific quest since 1966 because they are predicted to have far superior heat resistance, mechanical, electrical, optical and other physical properties, compared to their non-ladder counterparts. However, such ideal ladder polymers have remained unrealized materials because of the difficulty of making them. This project aims to develop a novel chemistry for making various ladder polymers. The project will also investigate the structural and physical properties of the new materials. The resulting new ladder polymers will enable testing of longstanding predictions of their properties. The new materials could also find applications in areas such as electronics, biosensors and wearable devices, aerospace structures, 3D printing, electrical energy storage (batteries and supercapacitors), and photovoltaic devices. The research project will also facilitate education of graduate and undergraduate students, including women and underrepresented minorities, in emerging science and engineering fields.PART 2: TECHNICAL SUMMARY Conjugated ladder polymers are predicted to have far superior structural and physical properties, compared to their non-ladder counterparts, due to their ribbon-like topology. However, these materials have largely remained a dream because the challenge of making them directly has remained unsolved. This research project aims to tackle this scientific challenge by exploring a novel approach. The overall goal of the project is to develop new chemistry for the synthesis of diverse well-defined, soluble, regioregular conjugated ladder polymers and investigate their properties. Specifically, the PI and his group will: (1) design and synthesize new multifunctional monomers suitable for making the regioregular conjugated ladder polymers; (2) develop polymerization methods for the one-step synthesis of the conjugated ladder polymers; (3) investigate the effects of regioregularity on the structure, morphology and physical properties of conjugated ladder polymers; and (4) investigate the morphology, charge transport and photophysics of the new conjugated ladder polymers. .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.

第一部分：非技术概述具有梯状、双链和带状分子链结构的聚合物称为梯状聚合物。自1966年以来，它们一直是科学探索的对象，因为与非梯形对应物相比，它们被预测具有远为优越的上级耐热性、机械、电气、光学和其他物理性能。然而，这种理想的梯形聚合物仍然是未实现的材料，因为它们的制造困难。该项目旨在开发一种用于制造各种梯形聚合物的新化学。该项目还将研究新材料的结构和物理特性。由此产生的新的梯形聚合物将能够测试其性能的长期预测。新材料还可以在电子、生物传感器和可穿戴设备、航空航天结构、3D打印、电能存储（电池和超级电容器）和光伏设备等领域找到应用。该研究项目还将促进研究生和本科生的教育，包括妇女和代表性不足的少数民族，在新兴的科学和工程领域。第2部分：技术概述共轭梯形聚合物预计具有远优于上级的结构和物理性能，相比于它们的非梯形对应物，由于它们的带状拓扑结构。然而，这些材料在很大程度上仍然是一个梦想，因为直接制造它们的挑战仍然没有解决。该研究项目旨在通过探索一种新的方法来应对这一科学挑战。该项目的总体目标是开发新的化学方法，用于合成各种定义明确的，可溶的，区域规则的共轭梯形聚合物，并研究其性能。具体而言，PI及其团队将：（1）设计和合成适合于制备区域规整共轭梯形聚合物的新的多官能单体;（2）开发一步合成共轭梯形聚合物的聚合方法;（3）研究区域规整性对共轭梯形聚合物的结构、形态和物理性能的影响;（4）研究了新型共轭梯形聚合物的形态、电荷传输和电子物理性质。该奖项反映了NSF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。
