A new D–π–A type intramolecular charge transfer Dyad System to detect F−: Anion induced CO2 sensing

An Ultrasensitive Fluorescent Paper-Based CO2 Sensor

“…27−30 One previous paper-based CO 2 sensor was reported, but it required colorimetric analysis of up to four dyes and was only demonstrated for solution-based sensing, 31 as opposed to operating in the gas phase, which is key for most of the aforementioned applications. To the best of our knowledge, only one previous paper-based CO 2 gas sensor has been demonstrated, 32 but no detection limits were reported.…”

“…Microfluidic paper-based devices are under widespread investigation for many biomedical applications, and paper sensors have been proposed for glucose monitoring, protein detection, and nerve agent detection. − One previous paper-based CO 2 sensor was reported, but it required colorimetric analysis of up to four dyes and was only demonstrated for solution-based sensing, as opposed to operating in the gas phase, which is key for most of the aforementioned applications.

Facile Synthesis of Sulfur-Containing Functionalized Disiloxanes with Nonconventional Fluorescence by Thiol–Epoxy Click Reaction

“…In addition, a weak emission peak at 497 nm was found. This finding is probably due to higher electronic conjugation induced by the π-π interaction between aromatic thiazole groups [46], while S→Si and N→Si coordination facilitates this interaction. The combined contribution can also explain higher fluorescence intensities found in E 1 T 6 and E 1 T 9 than in other samples, because additional aggregation of ester groups and N→Si coordination contributed by imidazole groups [24,47,48], exist within E 1 T 6 and E 1 T 9 , respectively.…”

An ESIPT-ICT steered naphthylthioic-based ionic probe with dual emissive channels exhibiting CHEF and CHEQ effects

“…In other accounts, benzothiazoles have been reported, describing pH effect on ESIPT and ICT, harnessing ESIPT and ICT processes in imines derivatives, triple-signaling mechanisms in Schiff bases and a dual mechanism strategy in imidazole. 66–70…”

“…In other accounts, benzothiazoles have been reported, describing pH effect on ESIPT and ICT, harnessing ESIPT and ICT processes in imines derivatives, triple-signaling mechanisms in Schiff bases and a dual mechanism strategy in imidazole. [66][67][68][69][70] In this work, we are reporting a uorescent dual molecular probe (M) bearing a hydroxyl and an amine group, thus exhibiting the ESIPT mechanism. The probe was designed to exploit the ESIPT mechanism known to exhibit excellent molecular recognition properties towards cations and anions, capable of forming tautomeric isomers.…”
