A naphthalene-phenanthro[9,10-d]imidazole-based π-conjugated molecule with a self-assembly-induced tuneable multiple fluorescence output exhibits artificial light-harvesting properties

Popis výsledku v původním jazyce

Among promising new materials, pi-conjugated organic molecules are considered an attractive platform for the design and development of a wide range of self-assembled superstructures with desirable optical and electrical properties necessary for use in organic optoelectronics applications. The optical and electrical properties of pi-conjugated organic molecules and their possible applications are usually determined by their primary molecular structure and their intermolecular interactions in the self-assembled state. However, satisfying the structural requirements for achieving tuneable optical properties is a difficult task, which makes the design and development of novel high-performance pi-conjugated organic systems for nano-optoelectronics a considerable challenge. In this paper, we report on the design and synthesis of a naphthalene-phenanthro[9,10-d] imidazole-based pi-conjugated Schiff base molecule (L1) that exhibits aggregation-induced tunable luminescence properties facilitated by solvent polarity. Upon varying the medium polarity of the self-assembly medium, L1 self-assembles into various superstructures with distinct morphologies and generates multiple tunable emission colours (blue-green-yellow-white). In a highly polar THF : water = 1 : 9 medium, it displays aggregation-induced white light emission. These single component-based white-light emitters attract broad attention due to their potential applications in lighting devices and display media. Computational studies incorporating full geometry optimization, time-dependent density functional theory (TDDFT) calculations and molecular dynamics (MD) simulations were utilized to elucidate the enhanced pi-pi interaction influenced by increasing solvent polarity and orbitals involved in electronic transitions associated with different self-assembled states. More importantly, we constructed a highly efficient artificial light-harvesting system in a THF : water = 1 : 1 medium based on self-assembled L1 and rhodamine B (RhB), where L1 acts as an energy donor and RhB acts as an acceptor, exhibiting a strong antenna effect at a substantial donor/acceptor ratio. Our findings provide a novel versatile approach for developing efficient artificial light-harvesting systems based on the supramolecular self-assembly of suitably designed pi-conjugated organic molecules with tuneable multiple emission properties.
