文摘
- •
A new bicarboxamidoquinoline-based fluorescent sensor 1 was synthesized.
- •
Sensor 1 performed ratiometric recognition Zn2+ without interference from Cd2+.
- •
The in situ generated 1–Zn2+ complex ratiometricly recognize citrate via displacement.
- •
The complex effectively discriminated citrate from common carboxylates.
