文摘
- •
TRIPOD-DNS exhibits AIEE properties and high quantum yield in aqueous media.
- •
TRIPOD-DNS shows amplified fluorescence quenching with TNP (KSV 1.57 × 109 M−1).
- •
TRIPOD-DNS aggregates undergo 50% fluorescence quenching with only 1% TNP.
- •
Linear change in FI over six orders of log [TNP] both in solution and solid state.
- •
LOD 13.2 × 10−18 g/cm2 by contact mode and 1 × 10−11 M in solution
