摘要: Five novel spirobifluorene derivatives, SPF-DM, SPF-MB, SPF-BB, BSPF-NA1 and BSPF-NA2 were synthesized starting from the readily available reagent 4,4 0 -bisalkylated biphenyl. Their linear absorption, fluorescence thermal properties examined their redox potential levels estimated by cyclic voltammetry. These compounds possess high stability. SPF-MB SPF-BB excellent spectral sensitivities to pH changes can be used as optical sensors of a wide range. The recognition behavior toward various metal ions has been evaluated in acetonitrile/water (15:1, v/v) solvent system. is highly selective recognizing Ag + . electroluminescent prop
