Novel Materials From Conjugated Polymers

该奖项由化学、材料研究和电气与通信系统部门颁发，隶属于材料合成与加工计划。本研究将把开环复分解聚合应用于具有多烯或其他电活性微域的嵌段共聚物的合成。一个目标是通过控制共轭共聚物共混物的形态来合成量子点。量子点的拉伸取向有望形成具有有用的各向异性光学特性的量子线。这些可以应用于基于分子的光学光栅。无机半导体和掺杂共轭聚合物之间的界面也将作为结和肖特基势垒器件进行评估。开环复分解途径将为共轭聚合物提供具有新颖机械、物理、光学和电学性能的新材料。

This award is made by the Divisions of Chemistry, Materials Research and Electrical and Communications Systems under the Materials Synthesis and Processing Initiative. The research will apply ring-opening metathesis polymerization to the synthesis of block copolymers having polyene or other electroactive microdomains. A goal will be the synthesis of quantum dots by morphology control of conjugated co-polymer blends. Stretch-orientation of quantum dots is expected to form quantum lines with useful anisotropic optical properties. These may find application as molecule-based optical gratings. Interfaces between inorganic semiconductors and doped conjugated polymers will also be evaluated as junctions and Schottky barrier devices. %%% Ring opening metathesis routes to conjugated polymers will provide new materials with novel mechanical, physical, optical and electrical properties.
