| 摘 要： | 能发射蓝绿色荧光的共轭高分子由单体1，4-二溴-2，3-萘-18-冠-6(M-2)与1，4-二乙烯基-2，5-二丁氧基苯(M-3)通过Pd催化的Heck偶联反应合成制得。通过荧光和紫外-可见光谱探讨了高分子对金属离子的响应性质，其中Hg2+能使高分子荧光淬灭、吸收增强，但AsⅢ、Pb2+和K+对高分子的荧光光谱改变很小。结果表明以2，3-萘-18-冠-6作为荧光团和识别位点的共轭高分子可作为有效识别Hg2+的荧光化学传感器。 |

| Abstract: | The conjugated polymer with strong green-blue fluorescence was obtained by the polymerization of 1,4dibromo-2,3-naphtho-18-crown-6(M-2)and 1,4-diviny1-2,5-dibutoxybenzene(M-3)via Pd-catalyzed Heck coupling reaction.The responsive properties of the polymer on metal ions were investigated by fluorescent and absorption spectroscopy.The results indicate that Hg~(2+)can effectively quench the fluorescence and apparently enhance the absorption of the polymer,whereas,As~Ⅲ,Pb~(2+)and K'do not produce obvious fluorescence change of the polymer.The results also show that the conjugated polymer incorporating 2,3-naphtho-18-crown-6 as fluorophore andrecognition site Call act as a special fluorescent chemosensor for Hg~(2+)detection. |
| Keywords: | 2, 3-Naphtho-18-crown-6 conjugated polymer fluorescent chemosensor Heck coupling reaction |
