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.

在这个由化学系大分子，超分子和纳米化学项目资助的项目中，丹尼森大学化学和生物化学系的Joseph J. Reczek教授正在准备一类新的有机材料，用于数据存储和信息加密。 这些材料具有介于液体和固体之间的性质，并且由含有芳环的分子构成。 在有机化学中，芳香分子非常稳定，不易与其他物质发生反应。 由于化学键由电子组成，芳香环能够在光学数据存储中导电和光，类似于分子尺度的电线。 Reczek教授设计并建造了一个互动教育展览“太阳能站”。 他还在俄亥俄州利金县的工厂博物馆为初中和高中学生组织和举办了一场动手“化学挑战”比赛。 他还建立了丹尼森大学、The Works和俄亥俄州州立大学纽瓦克分校分支之间的联合项目，将当地10-12岁的孩子和他们的父母带到校园进行STEM讲座和实验室演示。这项研究的重点是发现和开发新兴的超分子有机材料-芳香电荷转移液晶（ACT-LC）的全新性质和化学。 具体而言，研究，以促进出现的光电功能特性，材料的可调性，并控制分子组装在新的ACT-LC通过三个主要目标进行。 第一个目标集中在系统的设计，合成和组合/组装的一系列芳香族分子在一个模块化的方式，以更好地理解和预测组件的结构和ACT-LC体性能之间的关系，包括电荷转移（CT）持久性，扩展CT吸收范围（NIR），和激光可写的光学二向色性的分辨率。 在第二个目标中，具有大分子偶极的芳香族组分被并入ACT-LC中，以使正交材料对准用于场效应应用和增强的可写分辨率。 在最后一个目标中，新兴的ACT-LC被探索作为光学数据存储和信息加密的新方法的有机介质。 本研究为本科生提供了超分子和纳米化学的培训。 该项目也有潜力开发创新的功能性超分子纳米材料的技术应用。该奖项反映了NSF的法定使命，并已被认为是值得通过使用基金会的智力价值和更广泛的影响审查标准进行评估的支持。
