Dynamic Through-Space Interactions Driven by Molecular Motors
Distinct from the well-established paradigm of through-bond conjugation, through-space interaction (TSI) has emerged as a fundamental electronic phenomenon. Nevertheless, leveraging TSI for the rational design of organic functional materials remains a significant challenge, hindered by difficulties in conformational control and the absence of clear structure–property relationships. This project seeks to systematically investigate the photophysical and electronic properties, dynamic behaviors, and operational mechanisms of noncovalent TSI, utilizing light-driven molecular motors as a versatile platform. The work is structured around three core objectives: i) Developing a novel class of molecular motors powered by noncovalent conformational locks; ii) Achieving dynamic through-space charge transfer and multistate luminescent switching systems; iii) Constructing single-molecule junctions featuring tunable through-space interactions. These objectives are pursued through an integrated experimental and theoretical methodology, bridging multidisciplinary techniques and knowledge domains. Furthermore, the project advances theoretical studies on excited-state processes in molecular motors and photoclick reactions, thereby strengthening the photochemical research portfolio of the host group. Beyond scientific outputs, the project incorporates a comprehensive pathway to impact. Results are disseminated through peer-reviewed publications, international conferences, and social media, ensuring engagement with both academic and non-academic audiences. Building on the complementary expertise of the researcher and host institution, a two-way knowledge transfer is facilitated through tailored training, public outreach activities, and career development initiatives, enhancing the researcher’s professional trajectory and long-term employability within the European and worldwide research landscape.

Project objective
Different from the well-established theories based on through-bond conjugation, through-space interaction (TSI) has been proved to be another essential electronic interaction. However, it is still challenging to manipulate TSI and utilize it to develop organic functional materials due to the difficulties in conformational manipulation and the lack of structure-property relationships of TSI. Hence, this proposal aims to study the photophysical and electronic properties, dynamic behaviors, and working mechanisms of noncovalent TSI with the help of light-driven molecular motors. Herein, three objectives will be mainly investigated: i) a new type of molecular motor driven by the noncovalent conformational lock; ii) dynamic through-space charge transfer and multistate luminescent switches; iii) single-molecular junctions with dynamic TSI. These objectives will be realized using experimental and theoretical combined strategies which broadly interconnect multidisciplinary techniques and knowledge. The exploitation and dissemination are also involved in enhancing the expected outcomes and impacts of this proposal. Besides, the experienced researcher (ER) bears a strong background in photophysical chemistry, TSI, luminescent materials, and theoretical calculation, which is recognized by many awards and good publications. The host lab and supervisor have been renowned for molecular motor, photochemistry, and dynamic chemistry for 30 years, which has built a great experimental platform and scientific prestige, including Nobel Prize for Chemistry. Hence, the two-way transfer of knowledge will be smoothly launched based on the complementary experience between the two sides. In addition, a series of training plans and public activities are proposed to promote the ER's academic development, career perspectives, and employability. A detailed work plan and risk management are also reasonably discussed to guarantee the feasibility and high coherence of the proposed work packages.
