Published: July 1, 2024

Abstract Advancements in organic electronics are propelling the development of new material systems, where materials stand out for their unique benefits, including tunability and cost‐effectiveness. Organic single crystals ordered structure reduced defects, enhancing understanding relationship between performance. cocrystal engineering builds upon these foundations, exploring intermolecular interactions within multicomponent‐ordered crystalline to combine inherent advantages single‐component crystals. However, path realizing full potential cocrystals is fraught with challenges, structural mismatches, unclear cocrystallization mechanisms, unpredictable property alterations, which complicate effective different molecules. To deepen this promising area, review introduces mechanism formation, various stacking modes, growth techniques, highlights advancements multifunctional applications. The goal provide comprehensive guidelines high‐performance molecular materials, thereby expanding applications fields optoelectronics, photothermal energy, energy storage conversion.

Stepwise Epitaxial Growth of Core–Shell Organic Crystals for Advanced Dual-Emission Optical Applications

Journal of the American Chemical Society, Journal Year: 2025, Volume and Issue: unknown

Published: April 24, 2025

Organic core-shell heterostructures (CSHs) offer a unique platform for integrating complementary properties of the core and shell materials, leading to an optimized multifunctional performance. However, growth mechanism within CSHs remains unclear due poor crystallographic compatibility between different components fast crystallization. This study elucidates detailed process fabricating organic crystalline with tunable morphologies through in situ epitaxial approach, by employing IDF-TCNB (CryDFNB) IDT-TCNB (CryDTNB) charge-transfer cocrystals. After lattice matching three dimensions is satisfied, CryDTNB epitaxially grows on CryDFNB surface along specific orientations, sequence determined differences attachment energy. The bilayer structure results distinct dual-emission optical properties, including differentiated polarization, dual-band quasi-whispering gallery mode resonance, waveguides. work provides new framework design synthesis controlled structures advanced photonic functionalities.
