Abstract:
A hydrogen polysulfide mediated aziridine ring-opening reaction was discovered. Based on this reaction, a novel H₂Sₙ-specific chemosensor (AP) was developed. AP showed high sensitivity and selectivity for H₂Sₙ. Notably, the fluorescent turn-on product (1) exhibited excellent two-photon photophysical properties, a large Stokes shift, and high solid state luminescent efficiency.
