A novel red-emissive probe for colorimetric and ratiometric detection of hydrazine and its application in plant imaging

A novel windmill-shaped AIE-active pyrrolopyrrole cyanine: design, synthesis and efficient hydrazine detection

“…38 Hydrazine-triggered elimination of the acrylonitrile group produced a hydrazone derivative. [39][40][41][42][43][44][45][46] Moreover, hydrazine easily attacks the electron deficient boron atom to break the B-N bond. In the case of PPCy-TBE, both acrylonitrile groups and multiple B-N bonds would be potential recognition sites.…”

Robust ERα-Targeted Near-Infrared Fluorescence Probe for Selective Hydrazine Imaging in Breast Cancer

“…Since the first N 2 H 4 -specific fluorescent probe was reported in 2011, lots of N 2 H 4 -selective near-infrared (NIR) probes have been designed and successfully implemented for N 2 H 4 imaging . Mechanistic studies revealed that most of these N 2 H 4 -responsive probes were designed by utilizing several N 2 H 4 -specific reaction sites, such as malononitrile, acetyl, 4-bromo butyrate, and aldehyde . Considering that N 2 H 4 possesses strong reducing power, which can promote the formation of a hypoxic microenvironment through scavenging oxygen when N 2 H 4 greatly accumulates in tumor tissue.…”

A curcumin-based AIEE-active fluorescent probe for Cu2+detection in aqueous solution

“…To date, there have been prepared many varieties of AIE/AIEE-based nanoparticles as uorescent probes for biological imaging and chemical sensing in water or high water content environments. [13][14][15][16] These probes exhibit bright emission with high uorescent quantum yields in aggregated states. As one of the typical AIEgens, the highly twisted tetraphenylethylene (TPE) will limit the nonradiative energy transfer by hampering the intermolecular pp stacking in aggregated states.…”
