In this project funded by the Macromolecular, Supramolecular and Nanochemistry Program of the Chemistry Division, Mingdi Yan of the University of Massachusetts at Lowell will develop a general method to derivatize graphene and potentially achieve spatial selectivity. The potential of graphene to revolutionize electronics, photonics, and nanocomposite materials has been hampered by the availability and processability of graphene materials. The approach is to photolyze/thermalyze perfluorophenyl azide and its derivatives in the presence of graphene. The transient singlet perfluorphenyl nitrene will undergo a [2+1] cycloaddition with graphene pi-bonds to form aziridine groups on the graphene surface, and there is the potential for selectivity towards pi-bonds at the edge of the graphene sheet. The location of the functional groups will be determined by further derivatization with nanoparticles or C60 and imaging using AFM and TEM. The broader impacts include training female undergraduates and high school girls by engaging them in research, introducing them to strong role models, and dispelling myths surrounding careers for women in STEM. A new science course will be established at a local high school, targeting female students who may not otherwise take STEM courses in high school.This work would advance fundamental knowledge about attaching chemical species to graphene, a sheet-like material composed of a single layer of carbon atoms. The methods developed would allow the preparation of unique electronic materials that could have significant impacts on the fields of electronics and composite materials.

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，洛厄尔大学的马萨诸塞州大学的Mingdi Yan将开发一种衍生化石墨烯并有可能实现空间选择性的一般方法。 石墨烯对革新电子，光子学和纳米复合材料的潜力受到石墨烯材料的可用性和加工性的阻碍。 该方法是在存在石墨烯的情况下光水解/热分析叠氮化酶及其衍生物。 瞬态单重苯基全苯基硝基将使用石墨烯Pi键进行[2+1]环加成，以在石墨烯表面形成氮杂氨酸基团，并且在石墨烯薄板边缘的PI键有选择性的潜力。 官能团的位置将通过使用纳米颗粒或C60进一步衍生以及使用AFM和TEM进行成像来确定。 更广泛的影响包括培训女性大学生和高中女生通过参与研究，向他们介绍强有力的榜样，并分散围绕STEM女性职业的神话。将在当地的一所高中建立一个新的科学课程，以否则可能不会在高中学习STEM课程的女学生。这项工作将促进有关将化学物种附加到石墨烯的基本知识，这是一种由单层碳原子组成的类似薄片的材料。 开发的方法将允许制备独特的电子材料，这些材料可能会对电子和复合材料的领域产生重大影响。
