摘　　要：以4-溴甲苯为初始原料,经过多步反应得到一个新的含苯并咪唑基团的螺二芴衍生物SPF-BB.SPF-BB的紫外吸收光谱和荧光发射光谱对pH值非常敏感,可以作为宽泛响应的pH光学传感器.测试了SPF-BB在乙腈和水的体积比为15∶1的体系中,对各种金属离子的识别作用,结果表明,SPF-BB对银离子具有高的识别能力.A novel benzimidazole-based spirobifluorene derivative SPF-BB was obtained from 4- bromotoluene. SPF-BB possess excellent spectral sensitivities to pH changes and can be used as optical pH sensor of a wide pH range. The recognition behavior of SPF-BB toward various metal ions has been evaluated in a acetonitrile/water（ 15： 1, v/v） solvent system. SPF-BB is highly selective in recognizing Ag＋.
