In this project funded by the Macromolecular, Supramolecular and Nanochemistry Program of the Chemistry Division, Dr. Ivan Aprahamian of Dartmouth College develops easy to make, modular and tunable hydrazone-based switches, and studies ways to integrate them into polymers and liquid crystals. This proposal offers a new strategy for the development of adaptive functional materials (such as chemically activated actuators, sensors and molecular machines) by using synthetically straightforward building blocks. It is expected that this approach will facilitate the structure-property analysis of the systems, which will enable the rapid production of i) molecular machines for nanotechnology applications, ii) stimuli-responsive polymers that can convert chemical energy into mechanical motion, and iii) pH sensitive liquid crystals that can be used as sensors for environmental pollutants. The broader impacts of this research entail i) using the ACS SEED project and other endeavors to retain students of different levels (high school, undergraduate and graduate students) in the sciences, ii) piloting and assessing classroom technologies that can augment the learning experience of students, and iii) developing hands-on self-assembly demonstrations to educate the general public about important concepts related to supramolecular chemistry and nanotechnology.

在这个由化学部的大分子，超分子和纳米化学计划资助的项目中，达特茅斯学院的伊万·阿帕拉汉米安（Ivan Aprahamian）博士易于制造，基于模块化和可调的基于淡藏的开关，并研究将它们整合到聚合物和液晶中的方法。 该提案通过使用合成直接的构建块来开发自适应功能材料（例如化学激活的执行器，传感器和分子机器）的新策略。 预计这种方法将促进对系统的结构特性分析，这将使I）i）用于纳米技术应用的分子机器，ii）刺激反应性的聚合物，这些聚合物可以将化学能转化为机械运动，以及III）pH敏感液体，可以用作环境污染物的传感器。这项研究的更广泛影响i）i）在科学中使用ACS种子项目和其他努力来保留不同级别的学生（高中，本科和研究生），ii）ii）试验和评估可以增强学生学习经验的课堂技术，以及III的III），以及iii的iii）进行自我组装的自我组装示范，以培养相关的概念和重要的概念学教育。
