Millions of people in the world are suffering from senile dementia.Scientists have found that Alzheimers disease and aluminum are closely related.Also,they found that aluminum has damage on human brain,heart,liver kidney and immune system.A new β-diketone,3-(2,2,2-trifluoroethyl) chroman-4-one (4-TFC),which contains a trifluorinated alkyl group and a rigid chorman group,has been designed and successfully achieved,utilized for the synthesis of a new stable Eu3+ based 4-TFC lanthanide complex(1).The central Eu3+ ion was eight-coordinated by two O/N atoms from ancillary ligands and six oxygen atoms provided by three 4-TFC ligands.The complexes show highly luminescence response to 1,10-phenanthroline with a remarkableluminescence enhancement.In particular,the complex(1) can detect Al3+ ions with high selectivity and sensitivity in a moment and can be seen in naked eyes clearly under 365 nm.
