英文摘要	A new compound, n-(9-anthracylmethyl)-l-histidine (1). was synthesized and characterized by elemental analysis, electrospray ionization mass spectrometry (esi-ms), h-1-nmr. and c-13-nmr, etc. the effects of ph values and metal ions on the fluorescent intensity of compound 1 were studied. in neutral aqueous solutions, the fluorescence intensity of compound 1 increased upon addition of zn2+ or cd2+, while other metal ions (pb2+, co2+, hg2+, ni2+, and cu2+) quenched the fluorescence. among these metal ions, cu2+ and ni2+ had the strongest quenching capacity. they both formed a stable complex with compound 1 (1:2 molar ratio), and the complex constants were 2.88x10(6) and 1.12x10(6) l-2.mol(-2), respectively. the experimental results showed that static quenching was involved in adding cu2+ or ni2+ in aqueous solution of compound 1. on the basis of these studies. it nor fluorescent molecular logic gate was fabricated with cu2+ and ni2+ as two inputs and with emission of anthracene as the output.
