| Abstract: | 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＋. |
