Fluorescent organic hybrid nanosheets were generated by crystallization of polymers capped with luminogenic molecules exhibiting aggregation-induced emission characteristics (AIE). During crystallization of polymers, AIE molecules were expelled out of lamellar crystals of polymers, and finally resided on the surface. The fluorescent nanosheets with dangling AIE molecules showed sensitive and specific response to explosives. Such polymer crystallization-induced fluorescent nanomaterials offers a unique avenue to fabricate functional nanomaterials with AIE molecule-enriched domains for potential applications in nanodevices, biological engineering, and so on.
荧光有机杂化纳米片是由带有具有聚集诱导发光特性（AIE）的发光分子的聚合物结晶生成的。在聚合物结晶过程中，AIE分子被排出聚合物的层状晶体，最终驻留在表面。带有悬空AIE分子的荧光纳米片对爆炸物表现出灵敏且特异的响应。这种聚合物结晶诱导的荧光纳米材料为制造具有富含AIE分子区域的功能纳米材料提供了一条独特途径，可用于纳米器件、生物工程等潜在应用。
