摘要：
The binding properties of dibenzo-18-crown-6 ether (BTB, 1) and napthobenzo-18-crown-6 ether (NTB, 2), containing two thiazole units toward mono, and divalent cations, are outlined. The ion-selective properties of 1 and 2 were studied by measuring their fluorescent emission responses to alkali, alkaline earth, and transition metal ions. BTB (1) showed the highest binding constant toward Ag+ over Pb2+, Hg2+, and Cu2+. NTB (2) revealed a high selectivity toward Ag+ over Pb2+, Hg2+, and Cu2+.
