合成了一例三苯胺基团修饰的铂（Ⅱ）配合物PtppyTPA，并详细地表征了其结构及光物理性质。研究表明，三苯胺基团可有效激活PtppyTPA的聚集诱导发光（AIE）性能，使其在含水量为50%的乙腈中呈现显著的发光增强。以AIE活性的PtppyTPA为发光探针实现了对4种硝基芳烃包括硝苯地平（Nifedipine，NFD）、5-氯-2-硝基三氟甲苯（5-chloro-2-nitrotrifluorotoluene，ClNTFT）、4-溴-1-氟-2-硝基苯（4-bromo-1-fluoro-2-nitrobenzene，BrFNBz）及3-硝基三氟甲苯（3-nitrotrifluorotoluene， NTFT）的发光检测，利用Stern-Volmer方程拟合检测数据并计算了检测效率及检测限。PtppyTPA对上述硝基芳烃的检测效率分别为11.12，0.27，0.25，0.21 L/mmol；检测限分别为7.1，291.0，314.3，374.2 μmol/L。PtppyTPA对NFD具有最高的检测效率和最低的检测限。前线轨道能级及光谱交叠实验表明，PtppyTPA对NFD、ClNTFT、BrFNBz及NTFT的检测机理为电子转移。

A platinum(Ⅱ) complex PtppyTPA modified with triphenylamine is synthesized, whose structure and photophysical properties are characterized. The results show that triphenylamine can effectively activate the aggregation-induced emission (AIE) property of PtppyTPA, which can significantly enhance its luminescence in acetonitrile with water content of 50%. The AIE active PtppyTPA is employed as the luminescent probe to realize the luminescence detection of nitroaromatics, including nifedipine (NFD), 5-chloro-2-nitrotrifluorotoluene (ClNTFT), 4-bromo-1-fluoro-2-nitrobenzene (BrFNBz), and 3-nitrotrifluorotoluene (NTFT). Stern-Volmer equation was utilized to fit the detection data and calculate the detection efficiency with detection limits. The detection efficiency of PtppyTPA for nitroaromatics above is 11.12,0.27,0.25,0.21 L/mmol with the detection limits of 7.1, 291.0, 314.3, 374.2 μmol/L, respectively. PtppyTPA exhibits the highest detection efficiency and the lowest detection limit to NFD. The results show that the detection mechanism of NFD,ClNTFT,BrFNBz and NTFT by PtppyTPA can be attributed to electron transfer.
