Tetranitrile-anthracene as a probe for fluorescence detection of viscosity in fluid drinks via aggregation-induced emission

Abstract

An AIE-based fluorescent probe was developed for monitoring the viscosity change during the spoilage process of fluid drinks.

Construction of Carbon Dots with Color‐Tunable Aggregation‐Induced Emission by Nitrogen‐Induced Intramolecular Charge Transfer

“…[28] Highly viscous medium causes restriction of rotation (RIR) and the excited state relaxation occurs by enhanced fluorescence emission. [32][33][34][35][36] By this strategy, AIE-CD 5 was dispersed in solvents with different viscosities (acetic acid and PVA) and their fluorescence spectra were detected. It can be seen from Figure S7, Supporting Information, that the CD 5 in the PVA solution exhibits a phenomenon of increased fluorescence due to the restricted rotation of molecules at emission 620 nm wavelength.…”

Asymmetrical organic D–π–A conjugate with ‘V’-shaped crystal packing: quest to transcend the limits of photophysical properties and applications

“…The applications are further extended using the viscofluorochromic emission sensitivity of fluorescent dye in checking food quality. 45 Here, IAPY was utilized to detect the added thickener such as xanthan gum (food additive) and Na-CMC (sodium carboxymethyl cellulose, widely used in eyedrops) in water. Initially, we used water because it is the common constituent of any liquid food beverage.…”

Recent advances on anthracene-based photoinitiators of polymerization

“…Anthracene is a polyaromatic structure extensively used in Organic Electronics for the design of dyes for solar cells, [222] singlet emitters for organic light-emitting diodes [223] or fluorescent probes. [224,225] Interest for this structure was notably motivated by its low oxidation potential facilitating its incorporation in multi-layered devices. [226] However, the scope of application of anthracene also includes photopolymerization.…”
