摘要：

A series of 9-(cycloheptatrienylidene)fluorene derivatives were synthesized in good yields through the Suzuki or Sonogashira cross-coupling reactions. Fluorescence "off-on" behaviors of these compounds were investigated on the basis of variable acid concentrations. These compounds were shown to be acid-sensing fluorophores with utility as indicators in acidic environments.
