Development of semicarbazide-based fluorene as an AIE-active fluorescent sensor for Cu 2+ ions: a validation through experimental and DFT studies

Key Points

• This research aims to develop a fluorene-based fluorescent sensor for detecting Cu2+ ions using AIE (aggregation-induced emission) properties.
• Developed a semicarbazide-based fluorene sensor for Cu2+ detection.
• Integrated the sensor into molecular logic-gate operations for functional validation.
• Conducted DFT (Density Functional Theory) studies to support experimental findings.
• The sensor exhibits strong fluorescence enhancement in the presence of Cu2+ ions.
• Successful integration into molecular logic-gate operations indicates advanced application potential.
• Validation through DFT studies supports experimental results on sensor efficacy.
