Abstract
Understanding the relationship between material properties and supramolecular nanostructures is essential for elucidating how nanoscale molecular organizations govern macroscale photoluminescence (PL) properties. Here, we introduce a novel pyrene-based liquid crystal mesogen (Py-LCM) and systematically investigate how its molecular packing nanostructures and orientations influence photophysical material properties. Py-LCM exhibits diverse molecular packing structures depending on solvent polarity and concentration in the solution state, leading to a variety of controllable photophysical emissions. Thermodynamic and structural analyses in the solid state reveal that the formation of metastable and stable nanostructures of Py-LCM can be precisely controlled by modulating the kinetic pathway of nanoscale molecular self-assembly. Furthermore, by inducing macroscale molecular orientation, we achieve polarization-dependent photophysical emissions. Finally, we demonstrate the practical application of Py-LCM in optically encrypted systems, taking advantage of its distinct PL characteristics in both solution and solid states.
The multilevel assembly of conjugated polymers critically determines their electronic performance. However, establishing a direct correlation from molecular-level interactions to macroscopic morphology and charge transport properties remains challenging. In this work, advanced characterization techniques were employe...

Perylene dyes are key building blocks in organic optoelectronics and photocatalysis owing to their highly tunable electronic structure. Here, we investigate the impact of imide substitution with bulky 2,6‐isopropylphenyl (iPr) on the structural and electronic properties of perylene diimide (PDI) monolayers on Ag(111)....

Organic semiconductor crystals with long-range order and designable properties are pivotal in optoelectronic devices. Organic crystals bonded by weak intermolecular interactions usually follow non-classical crystallization trajectories, yielding polymorphs with distinctive properties but extremely difficult to control....
Mechanochromic structural‐color hydrogels are promising materials for sensing and display applications; however, simultaneous control of hue and brightness remains challenging. Here, we report a simple and effective strategy for tuning optical parameters by adsorbing alkyltrimethylammonium ions (CnTMA, where n denotes...
Supramolecular bulk materials composed of low-molecular-weight compounds offer a promising pathway toward sustainable materials. However, achieving a macroscopic structural order and tuneable mechanical properties without relying on covalently bonded macromolecular components remains a significant challenge. We develop...
