Two novel pyrene-armed calix[4]arenes by triazole connection were synthesized using "click" chemistry. Compound 1 with two pyrene subunits appended to the lower rims of the calix[4]arene shows ratiometric fluorescence response toward Zn(2+) and selective fluorescence quenching toward heavy metal ions such as Cu(2+), Hg(2+) and Pb(2+); while compound 2 with one pyrene subunit exhibits significant fluorescence quenching toward Cu(2+) and moderate quenching behaviour toward Hg(2+). By utilizing the different fluorescence behavior of 1 toward Zn(2+) and Cu(2+) inhibition (INH) and not or (,NOR) logic gates were established.
