摘　　要：Two kinds of novel styryl chemosensory 2-FMNC and 3-FMNC, were designed and synthesized by an apporiate introduction of 9-benzylidene-9H-fluorene group as fluorophore with the aim at avoiding photoisomerisation. These 9-benzylidene-9H-fluorene derivatives showed the similar selectivity and sensitivity upon addition of metal ions. The sensitivity of FMNC to alkaline earth metal ions was Ba2＋〉 Sr2＋〉Ca2＋≈Mg2＋.Two kinds of novel styryl chemosensory 2-FMNC and 3-FMNC, were designed and synthesized by an apporiate introduction of 9-benzylidene-9H-fluorene group as fluorophore with the aim at avoiding photoisomerisation.
