Abstract:

The quinacridone derivative 5,12-bis[6-(2-amino-ethylamino)-hexyl] qunacridone(BAEAHQA) which can be used as chelate ligand to coordinate with metal ions,was successfully incorporated into mesoporous molecular sieve MCM-41. The emission spectra indicate that BAEAHQA/MCM-41 emits a great yellowish-green light,which is similar with BAEAHQA in liquid state. And metal ions could quench the luminescence of BAEAHQA/MCM-41,especially when Co2+ ions exist,the luminescence of BAEAHQA/MCM-41 was quenched completely. It is suggested that BAEAHQA/MCM-41 can be used as the metal ions sensing material.

Key words: Metal ions sensing material; 5,12-Bis[6-(2-amino-ethylamino)hexyl] qunacridone(BAEAHQA); MCM-41; Co2+
