Molecular keypad controlled circuit for Ce(iii) and NO3? ions recognition by μw synthesized silicon-embedded organic luminescent sensor

摘要

This report demonstrates the mimicking of an electronic circuit diagram towards Ce( III ) ion sensing response supported by molecular keypads. The probe naphthyl based triazole linked silatrane (NTS) was efficiently synthesized using a series of microwave mediated reactions. The luminescent sensor NTS was explored for the ion sensing response towards Ce( III ) ions using DMSO and DMSO?:?H _(2) O 4?:?1 (v/v) as solvent media, respectively. The role of water in Ce( III ) ion sensing was detected as ‘turn-off’ response that contradicts the ‘turn-on’ with DMSO. Further, the sensing of NO _(3) ~(?) ions by NTS–Ce( III ) ensemble was associated with blue shift on absorption maxima. These mimicking response studies were sketched as circuit diagrams assisted by molecular keypad behaviour as IMPLICATION output logic gate.
