Increasing worldwide demand for energy is driving not only the search for alternative (non-fossil) fuel sources, but also the exploration of new technologies for harvesting, transferring and processing energy and information. In the post-transistor digital age, new electronic and optical devices are required to have improved performance relative to conventional silicon-based systems; they must be smaller, lighter and more efficient. In light of these demands, the case for organic materials as building blocks for new electronic, optical and magnetic materials holds much appeal. Recent Nobel Prizes in Chemistry (2000) and Physics (2010), awarded for groundbreaking work in conductive organics, reflect both the interest and progress that has been made in recent years. Essential to the continuation of these technological advancements are new materials by design with tailor made properties. This endeavour, which inspires research in industrial and academic settings, represents the underlying motivation for the present research proposal involving the design and development of new multifunctional materials for molecular electronics. We aim to address this task by making novel innovative contributions to several areas of broad interest. Specific research directions are: 1. Heterocyclic Radicals: Here our focus is twofold; we seek to uncover the fundamental reactivity that governs isolable neutral radicals, and to deploy these within leading materials applications. We will establish the synthetic methodology to prepare a variety of new chalcazyl radicals and polyradicals, and implement them into conductive, magnetic or optical devices. This work will produce novel and impactful chemical insight into the synthesis, structure and properties of open-shell compounds in order to develop innovative materials that have the diversity and exceptional properties required to transform materials design for molecular electronics. 2. Ligand Design & Coordination Chemistry: Exploiting our expertise in heteroaromatic materials, we will tap into the enormous potential of chalcazyls as ligands. We will prepare polydentate ligands, and develop lightweight, densely packed materials in which the metal ions can communicate through the ligand. This work will address key factors that affect the synthetic methodology of the spectacularly versatile, underexplored family of chalcazyls as ligands, and provide novel insight into the intriguing physical properties of multi-metallic complexes/polymers/networks. 3. Covalent Organic Frameworks (COFs): In this new research direction, we will develop radical-based COFs. This high-risk work promises to take our research to the next level, providing a new strategy and direction in the quest for high-performance-conjugated polymers that can pave the way for innovations in fields from organic electronics and energy storage to gas separation and storage.

世界范围内对能源日益增长的需求不仅推动了寻找替代（非化石）燃料来源，而且推动了探索收集、转移和处理能源和信息的新技术。在后晶体管数字时代，新的电子和光学器件需要比传统的硅基系统具有更好的性能；它们必须更小、更轻、更高效。鉴于这些需求，有机材料作为新型电子、光学和磁性材料的基础材料具有很大的吸引力。最近的诺贝尔化学奖（2000年）和诺贝尔物理学奖（2010年），授予导电有机物的开创性工作，反映了近年来取得的兴趣和进展。对这些技术进步的延续至关重要的是通过设计具有定制性能的新材料。这一努力激发了工业和学术环境的研究，代表了本研究提案的潜在动机，涉及设计和开发用于分子电子学的新型多功能材料。
