Abstract Flavonols, named as 3-hydroxyl-2-phenyl-1-benzopyran-4-one, are important
natural botanical functional pigments widely distributing in fruits, vegetables, and flowers …

Fluorescein molecules are extensively used to develop fluorescent probes for various
analytes due to their excellent photophysical properties and the spirocyclic structure. The …

A fluorescent chemosensor for fast detection of Cu 2+ ion has been established based on a
novel pyridine-appended half-salamo-based compound. The chemosensor PHS is easy to …

A novel double-armed salamo-based probe DAS for detecting tryptophan and Al 3+ was
successfully designed and synthesized. The probe DAS showed good selectivity to …

Widely distributed natural flavonols with broad-spectrum pharmacological activities are
unique dual emission fluorescence dyes. The excited state intramolecular proton transfer …

A novel and simple turn-on fluorescence probe (HD) for Al 3+ detection was successfully
developed based on flavonol derivatives. This probe exhibited a significantly enhanced …

Fluorescent sensors available for metal ions detection have been extensively developed in
recent years. However, developing an ultrasensitive fluorescent sensor for highly selectively …

Al 3+ is commonly utilized in daily life, however, the excessive accumulation of Al 3+ within
organisms can result in severe health problems. Herein, a highly efficient fluorescent probe …

A multiple turn-on fluorophore (FHCS), combining fluorescein, hydrazone, cyanuric chloride
and salicylaldehyde chromone into a molecule, was identified and developed based on …

Herein, a rational combination of dispersive solid-phase sorbent and 2-(2, 4-
Dihydroxyphenyl)-3, 5, 7-trihydroxychromen-4-one (morin) was proposed for sensitive and …
