摘　　要：采用两步溶剂热法,先将金属原子锆固定在配体四苯基卟啉(Tetraphenylporphyrin,TPP)中间空腔中,然后将该金属原子与具有聚集诱导发光(Aggregation-inducing emission,AIE)效应的配体四[4-(4′-羧基苯基)苯基]乙烯(Tetrakis[4-(4′-carboxyphenyl)phenyl]ethylene,H_(4)ETTC)上的羧基配位,制备得到了一种新型二维有机金属层状荧光传感器(记作Zr-TP MOL)。采用SEM、TEM、FT-IR、TGA等对Zr-TP MOL的微观形貌、化学结构和热稳定等性能进行表征,并将Zr-TP MOL作为荧光化学传感器对2,4,6-三硝基酚(2,4,6-Trinitrophenol,TNP)进行响应检测。结果表明:Zr-TP MOL是一种纳米级球体富集的非晶体材料,具有良好的热稳定性和荧光稳定性;Zr-TP MOL作为新型荧光化学传感器,对TNP检测具有选择性高、超敏、响应快速以及抗干扰能力超强等特征。该研究结果可为荧光传感检测硝基芳烃化合物(Nitro-aromatic compounds,NACs)类炸药原料奠定实验基础。By using a two-step solvothermal method,the metal atom zirconium was first immobilized in the middle cavity of the ligand tetraphenylporphyrin(TPP),and then the metal atom was coordinated with the carboxyl on the ligand tetrakis[4-(4′-carboxyphenyl)phenyl]ethylene(denoted as Zr-TP MOL)with aggregation-induced emission(AIE)effect,to prepare a novel two-dimensional organic metal layered fluorescent sensor(denoted as Zr-TP MOL).The micro-morphology,chemical structure and thermal stability,etc.of Zr-TP MOL were characterized by SEM,TEM,FT-IR and TGA,etc.,and Zr-TP MOL was adopted as a fluorescent chemical sensor for 2,4,6-trinitrophenol(TNP)for response detection.The results showed that:Zr-TP MOL was an amorphous material enriched by nano-spheres with good thermal stability and fluorescence stability;Zr-TP MOL,as a novel fluorescent chemical sensor,had high selectivity,hypersensitivity,quick response and ultra-strong anti-interference ability,etc.for TNP detection.These research results can lay an experimental foundation for the detection of nitro-aromatic compounds(NACs)explosive materials based on fluorescence sensing.
