In this project funded by the Macromolecular, Supramolecular and Nanochemistry Program in the Division of Chemistry, Professor Joseph J. Reczek of the Department of Chemistry and Biochemistry at Denison University is preparing a new class of organic materials for potential use in data storage and information encryption. These materials have properties between those of liquids and solids and are constructed from molecules that contain aromatic rings. In organic chemistry, aromatic molecules are very stable and do not readily react with other substances. Since chemical bonds consist of electrons, aromatic rings are capable of conducting electricity and light in optical data storage, similar to molecular-scale wires. Professor Reczek designs and constructs an interactive educational exhibit, "The Solar Station". He also organizes and conducts a hands-on "Chemistry Challenge" competition for both middle and high school students at The Works Museum in Licking County, Ohio. He has also established a joint program between Denison University, The Works and The Ohio State University Newark branch to bring local 10-12 year-olds and their parents onto campuses for STEM lectures and laboratory demonstrations.This research focuses on the discovery and development of fundamentally new properties and chemistries in an emerging class of supramolecular organic materials, aromatic charge-transfer liquid crystals (ACT-LCs). Specifically, studies to advance the emergence of optoelectronic functional properties, material tunability, and controlled molecular assembly in new ACT-LCs are conducted through three main objectives. The first objective concentrates on the systematic design, synthesis, and combination/assembly of a series of aromatic molecules in a modular fashion to better understand and predict relationships between component structure and ACT-LC bulk properties including charge-transfer (CT) persistence, extended CT absorption range (NIR), and resolution of laser-writable optical dichroism. In the second objective, aromatic components having a large molecular dipole are incorporated into ACT-LCs to align orthogonal materials for field-effect applications and enhanced writable resolution. In the last objective, emerging ACT-LCs are explored as organic media for new methods of optical data storage and information encryption. This research provides training for undergraduate students in supramolecular and Nanochemistry. The project also has the potential to develop creative functional supramolecular nanomaterials for technological applications.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.

在该项目由化学系的大分子，超分子和纳米化学计划资助的项目中，丹尼森大学化学和生物化学系的Joseph J. Reczek教授正在准备一种新的有机材料，用于潜在的数据存储和信息加密。 这些材料在液体和固体之间具有特性，并由包含芳香环的分子构建。 在有机化学中，芳香族分子非常稳定，并且不容易与其他物质反应。 由于化学键由电子组成，因此芳香环能够在光学数据存储中传导电和光，类似于分子尺度电线。 Reczek教授设计并构建了一个互动的教育展览“太阳能站”。 他还在俄亥俄州舔县的工作博物馆组织并为中学和高中学生组织并进行了“化学挑战”竞赛。 He has also established a joint program between Denison University, The Works and The Ohio State University Newark branch to bring local 10-12 year-olds and their parents onto campuses for STEM lectures and laboratory demonstrations.This research focuses on the discovery and development of fundamentally new properties and chemistries in an emerging class of supramolecular organic materials, aromatic charge-transfer liquid crystals (ACT-LCs). 具体而言，通过三个主要目标进行了用于推进新ACT-LCS中光电功能特性，材料可调性和受控分子组装的研究。 第一个目标集中在模块化方式的系统设计，合成和组合/组合上，以更好地理解和预测组件结构和ACT-LC批量特性之间的关系，包括电荷转移（CT）持久性，扩展CT吸收范围（NIR），以及激光透射的光学dichroble Dichroiss的分辨率。 在第二个目标中，将具有较大分子偶极子的芳族组分纳入ACT-LCS中，以使正交材料对齐用于现场效应应用和增强的写入分辨率。 在最后一个目标中，新兴ACT-LC被探讨为有机媒体，用于新的光学数据存储和信息加密方法。 这项研究为超分子和纳米化学的本科生提供了培训。 该项目还具有为技术应用开发创造性的功能性超分子纳米材料。该奖项反映了NSF的法定任务，并使用基金会的知识分子优点和更广泛的影响评估标准，认为值得通过评估来获得支持。
