Triphenylamine indanedione as an AIE-based molecular sensor with one-step facile synthesis toward viscosity detection of liquids

Abstract

Viscosity is one of the most important physical parameter toward liquid, noninvasive and effective viscosity inspection method toward liquid safety is urgent to be developed. In this study, two kinds...

A sustainable viscosity-sensitive isoliquiritigenin-based molecular sensor for liquid food safety inspection

“…27 Commonly, the viscosity will increase with the added amounts of thickeners, and the time to flow through the oesophagus may be increased. 28 Thus, three kinds of food thickener with different amounts (from 1 g kg −1 to 5 g kg −1 ), were dissolved in pure water, and we expected that the thickening effect could be monitored by the fluorescent method. As shown in Fig.…”

Cinnamaldehyde‐based Natural Product as Viscosity‐Sensitive Sensor toward Liquid Safety Inspection

“…We also explored the application of DLCA in the actual samples with the existence of thickeners, since various food thickeners were added to enhance the consistency, homogeneity and texture of liquids quite often [32] . The viscosity will enhance after the addition of thickeners, and the time to flow through the tongue is increased, the texture would be better performance [33] . Sodium carboxymethyl cellulose (SCC), pectin (Pec), xanthan gum (XG) with different amounts (from 1 g/kg to 5 g/kg), were dissolved in the pure water, and the viscosity changes were monitored by the method of fluorescent spectra.…”

Mechanistic analysis of viscosity-sensitive fluorescent probes for applications in diabetes detection

“…Recently, Lingfeng Xu et al designed and developed an AIE molecular sensor utilising the strong electron donating effect of triphenylamine and acceptor property of indanedione. 27 The donor and acceptors were connected through the thiophene or benzene unit, leading to a rotatable structure. The sensor was used to monitor viscosity variations due to the addition of food thickeners.…”
