主　　题：phase-change aggregation-induced emission selfassembly high-resolution multi-color patterns 

摘      要：High-resolution organic arrays with diverse pixel types hold significant promise for various applications,such as full-color displays and photonic *** direct growth of such arrays(e.g.,high-resolution multi-color patterns)cannot be achieved in a single step with conventional ***,we present a viable approach integrating a bottom-up solution strategy with phase-change materials(PCMs),specifically aggregation-induced emission(AIE)*** intentional self-assembly,color-programmable organic micro-patterns featuring distinct phases or colors were ***,manipulating the amount of involved substance for nucleation/crystallization was achieved by adjusting the sizes of pre-defined nucleation *** precise control resulted in varied phases and colors for each ***,high-resolution organic micro-arrays with transfer-free multi-color pixels were directly *** may open avenues for seamless,transfer-free growth of multifunctional micro-patterns using PCMs,holding immense potential for applications in high-resolution full-color imaging/displays,photonic crystals,information storage,and encryption,etc.
