Revisiting small‐molecule fluorescent probes in food freshness detection

Smart Molecules, EarlyView.
Fluorescent probes serve as versatile tools for food freshness monitoring. This review summarizes recent advances in probes targeting biogenic amines, hydrogen sulfide, pH values, and other key spoilage markers, highlighting their design principles, sensing mechanisms, and practical applications in food quality monitoring. Abstract Food spoilage driven

Excited-state proton-transfer kinetics in 1-naphthol, 1-naphthol-sulfonates, and organometallic complexes [PDF]

, 1980
The dissociation of 1-naphthol in aqueous solution occurs so rapidly that the fluorescence from the neutral form, ROH, has been previously described as completely extinguished or hardly noticeable.

Development of an imidazole salt catalytic system for the preparation of bis(indolyl)methanes and bis(naphthyl)methane.

PLoS ONE, 2019
Imidazolium salts are shown to catalyze the rapid room temperature reaction of indoles or naphthol with aldehydes to provide bis(indolyl)methanes or bis(naphthol)methane in excellent yields and the reaction proceeds optimally in dichloromethane with no ...

GMP‐compliant production, validation and dosimetry of clinical grade [18F]3‐(3‐fluoropropyl)‐2‐phenyl‐2,3‐dihydrobenzo[d]thiazole ([18F]FPBT) for oxidative stress PET imaging

British Journal of Pharmacology, EarlyView.
Background and Purpose Oxidative stress plays a critical role in the pathophysiology of various diseases, yet current methods for its non‐invasive detection remain limited. This study aimed to systematically validate a superoxide‐selective PET tracer, [18F]FPBT, for the early diagnosis and therapeutic monitoring of oxidative stress‐related conditions ...

Ultrafast solvent-assisted level crossing in 1-Naphthol [PDF]

, 2013
The nonadiabatic inversion dynamics of the energetic order of the electronic excited states of the photoacid 1-naphthol have been revealed by ultrafast spectroscopy on a femtosecond timescale (see picture; IC=internal conversion).

Efficient Cleavage of pUC19 DNA by Tetraaminonaphthols

ChemistryOpen
In an attempt to create models of phosphodiesterases, we previously investigated bis(guanidinium) naphthols. Such metal‐free anion receptors cleaved aryl phosphates and also plasmid DNA.

One-Pot Synthesis of 2′-Aminobenzothiazolo-Arylmethyl-2-Naphthols Catalyzed by NBS under Solvent-Free Conditions

The Scientific World Journal, 2013
To develop a new facile protocol for the synthesis of 2′-aminobenzothiazolo-arylmethyl-2-naphthol derivatives, N-bromosuccinimide (NBS) was used as an efficient catalyst for the one-pot synthesis of 2′-aminobenzothiazolo-arylmethyl-2-naphthols in ...

Rearrangements of Cycloalkenyl Aryl Ethers

Molecules, 2016
Rearrangement reactions of cycloalkenyl phenol and naphthyl ethers and the acid-catalyzed cyclization of the resulting product were investigated. Claisen rearrangement afforded 2-substituted phenol and naphthol derivatives.
