Mercury Ion Chemosensor Derived from Barbiturate Acid with Aggregation-Induced Emission Effect
نویسندگان
چکیده
The detection of toxic metals is indispensable for water safety. In this paper, a small molecule aggregation-induced emission (AIE) with barbiturate group was synthesized. It combined mercury ions to form stable metal complex so as enhance the color solution achieve visualization ion detection. fluorescent showed good selectivity and anti-interference ability had low limit (DL = 22.27 nM) ion.

Aggregation-induced emission of siloles
Aggregation-induced emission (AIE) is a unique and significant photophysical phenomenon that differs greatly from the commonly acknowledged aggregation-caused emission quenching observed for many π-conjugated planar chromophores. The mechanistic decipherment of the AIE phenomenon is of high importance for the advance of new AIE systems and exploitation of their potential applications. Propeller...
متن کاملFluorogen-free aggregation induced NIR emission from gold nanoparticles.
Controlled diluted aqua regia addition leads to NIR (near infrared) luminescence from aggregated gold nanoparticles at 916 nm. This turn-on luminescence has been observed for gold nanoparticles, regardless of reductants used in their preparation. These aggregated nanoparticles are nontoxic and have been used for bioimaging in human liver carcinoma cells.
متن کاملEvidence of aggregation induced emission enhancement and keto-enol-tautomerism in a gallic acid derived salicylideneaniline gel.
A novel salicylideneaniline type fluorescent organogelator based on a 3,4,5-(tri-dodecyloxy)benzoyl group immobilizes aromatic solvents. The resulting gels show enhancement in emission and thermochromic/non-photochromic behaviour during sol-to-gel transition.
متن کاملStereochemical modulation of emission behaviour in E/Z isomers of diphenyldipyrroethene from aggregation induced emission to crystallization induced emission.
Herein, we report the synthesis, separation and characterisation of the E- and Z-isomers of dipyrrolyldiphenylethene to study their emission behaviour in the aggregation state and solid state. The E-isomer showed pronounced aggregation induced emission (AIE) whereas the Z-isomer showed crystallization induced emission (CIE). The present study explains that the emission behaviour (AIE/CIE) is de...
متن کاملAggregation-induced emission-fluorophores and applications.
Aggregation-induced emission (AIE) is a novel photophysical phenomenon found in a group of luminogens that are not fluorescent in solution but are highly emissive in the aggregate or solid state. Since the first publication of AIE luminogens in 2001, AIE has become a hot research area in which the number of research papers regarding new AIE molecules and their applications has been increasing i...
