| Popis: | 100 Three new sensitive and selective cyanide chemosensors 15-17 were prepared, and their chromogenic and fluorogenic behaviours toward various anions were investigated. Among them, receptor 15 shows exclusive response toward CN- ion. When cyanide ions were added (EtOH/H2O = 3/7, v/v), the pronounced enhancement of the fluorescence, as well as the color change of 15 was observed so that micromolar concentrations of cyanide were detectable by the naked eye. The use of test strip of the receptor 15 to detect CN- ion was also reported. |
