Azaindole modified imine moiety as fluorescent probe for highly sensitive detection of Fe3+ ions

Carbon source self-heating: ultrafast, energy-efficient and room temperature synthesis of highly fluorescent N, S-codoped carbon dots for quantitative detection of Fe(iii) ions in biological samples

“…As listed in Table S4, † the presented method has better sensitivity and a much wider linear range for the detection of Fe 3+ compared with the previously reported PL CDbased nanosensors and other uorescent nanoprobes. 42,[52][53][54][55][56][57][58][59][60] Therefore, the as-synthesized N, S-codoped CDs have great potential for the detection of Fe 3+ in real samples.…”

Click synthesis of a quinoline-functionalized hexahomotrioxacalix[3]arene: A turn-on fluorescence chemosensor for Fe3+

“…Given the paramagnetic nature of Fe 3+ , most reported Fe 3+ fluorescent chemosensors are based on a fluorescence quenching mechanism, whereas sensors exhibiting fluorescence enhancement (turn-on) sensing behaviour are somewhat limited [15][16][17][18][19][20]. Nevertheless, turn-on sensors do have some advantages not so easily attainable by turn-off sensors, including the ease of detecting low concentrations against a dark background, reduced false-positive signals, and enhanced sensitivity [21][22][23].…”
