项目摘要

Atomically precise nanographenes and related structures have gained significant importance in several areas of chemistry and materials science due to their unmatched optoelectronic properties. Yet, their full potential has not yet been exploited as several types of very promising structures cannot yet be prepared efficiently due to the lack of synthetic methods. The central objective of our research program is to develop innovative and versatile synthetic tools for the preparation of unprecedented, well-defined nanographenes (NGs), graphene nanoribbons (GNRs) and carbon allotropes with unique physical properties. This proposal is separated into four related themes: ******1. Metal-free photochemical reaction for intramolecular C-C coupling; ***2. GNRs and other one-dimensional carbon allotropes; ***3. Zigzag-edged NGs and GNRs; ***4. Conjugated molecules with a high diradical character. ******As a short- to medium-term project, we will pursue our efforts in the development and study of a reaction called the cyclodehydrochlorination (CDHC) for the preparation of NGs, GNRs and new carbon allotropes of different topologies by following three strategies. Our medium- to long-term goal will be to use this method to prepare unprecedented topologies of sought-after armchair GNRs whose synthesis is not yet possible using known wet chemistry strategies. Also, low bandgap, one-dimensional carbon allotropes with 5- and 7-membered rings will be prepared. The best candidates will be integrated as active materials in organic electronics devices.******Another medium-term objective is to prepare long, stable zigzag-edged nanographenes with low bandgap. We propose an innovative approach that consists of using short, stable zigzag-edged molecules, such as naphthalene and pyrene, as building blocks to prepare longer analogs. Short, definite-length model compounds will be prepared using different synthetic approaches to study their stability and the relationships between their structures and properties. Our long-term goal is to synthesize zigzag-edged GNRs and evaluate their singlet fission properties.******NGs and GNRs will be used as scaffolds to prepare molecules with a high diradical character. We propose to generate diradicals "on demand" in various NGs and GNRs by using tunable steric hindrance through coordination chemistry with metals within the aromatic skeleton. ******The discoveries that will be made using our innovative approaches will have a significant impact on physical organic chemistry and materials science. This research program is based on our long-standing expertise in the area of aromatic compounds and fits perfectly with our long-term objective, which is to have a access to unorthodox carbon-rich molecules and materials that could surpass the best-known materials in electronics applications.
原子精确的纳米石墨烯和相关结构由于其无与伦比的光电性能在化学和材料科学的几个领域中具有重要意义。然而,它们的全部潜力尚未被开发,因为由于缺乏合成方法,还不能有效地制备几种类型的非常有前途的结构。我们研究计划的中心目标是开发创新和通用的合成工具,用于制备前所未有的,定义明确的纳米石墨烯(NG),石墨烯纳米带(GNR)和具有独特物理特性的碳同素异形体。本提案分为四个相关主题:*****1。用于分子内C-C偶联的无金属光化学反应; *2. GNR和其他一维碳同素异形体;*3.锯齿形边缘NG和GNR; *4.具有高双自由基特征的共轭分子。****** 作为中短期项目,我们将继续努力开发和研究称为环化脱氯化氢(CDHC)的反应,以制备NG,GNR和不同拓扑结构的新碳同素异形体。我们的中长期目标将是使用这种方法来制备前所未有的受欢迎的扶手椅GNRs拓扑结构,其合成使用已知的湿化学策略尚不可能。此外,将制备具有5元环和7元环的低带隙的一维碳同素异形体。最好的候选者将作为活性材料集成在有机电子器件中。另一个中期目标是制备具有低带隙的长而稳定的锯齿状纳米石墨烯。我们提出了一种创新的方法,包括使用短的,稳定的边缘分子,如萘和芘,作为构建块,以制备更长的类似物。短的,确定长度的模型化合物将使用不同的合成方法制备,以研究其稳定性及其结构和性能之间的关系。我们的长期目标是合成带边缘的GNR,并评估它们的单线态裂变性质。NG和GNR将被用作支架来制备具有高双自由基特征的分子。我们建议通过使用可调的空间位阻,通过与芳香族骨架内的金属的配位化学,在各种NG和GNR中“按需”产生双自由基。** 使用我们的创新方法所取得的发现将对物理有机化学和材料科学产生重大影响。该研究计划基于我们在芳香族化合物领域的长期专业知识,完全符合我们的长期目标,即获得非正统的富碳分子和材料,这些分子和材料可以超越电子应用中最知名的材料。
