“…In our previous work, we have synthesized a similar probe L3 [28] with diaminomaleonitrile as the receptor unit and bis-cyano substituted isophorone as the electron acceptor. Photophysical properties and recognition test of L3 showed that it could recognize Cu 2+ in CH 3 CN.…”

“…1 As the third-most abundant ion (after ferric and zinc ions), copper plays important biological roles in human bodies, such as enzyme cofactors, structural components of proteins, and so on. 2,3 It is an essential metal at the trace level, but its excess is linked to environmental contamination and human diseases. An elevated concentration of copper, which exists as free copper ion (Cu 2+ ), is toxic to bacteria or aquatic organisms, and can hamper the self-purification capability of the sea or rivers.…”

This study aimed to develop a label-free, sensitive, selective, and environment-friendly fluorescent peptide probe His-His-Trp-His (HHWH) for determining the concentration of copper ion (Cu 2+ ) in aqueous solutions. The results demonstrated that the designed HHWH has a high selectivity and sensitivity for monitoring the concentration of free Cu 2+ via quenching of the probe fluorescence upon a binding of Cu 2+ . The fluorescence intensity of the HHWH had a linear relationship with the concentration of Cu 2+ between 10 nM and 10 μM, and the detection limit was 8 nM. Furthermore, HHWH could be regenerated with sulfide ions at least five times. The concentrations of Cu 2+ in three different real water samples were detected using this probe, and the results were consistent with the one detected using an atomic absorption spectrometer. Thus, HHWH can be used as an accurate and feasible fluorescent peptide probe for detecting Cu 2+ in aqueous solutions.

A novel unsymmetrical photochromic diarylethene 1-[2-methyl-5-(4-fluorophenyl)-3-thienyl]-2-[2-methyl-5-(3-methoxy-4-formyphenyl)-3-thienyl]perfluorocyclopentene(1o), was successfully synthesized and its properties were investigated in detail, including photochromic reactivity kinetics and concentration effect. The results showed that the compound exhibited remarkable photochromism, changing between colorless and blue in solution by photoirradiation, respectively. What is more, the kinetic experiments illustrated that the cyclization/cycloreversion process of this compound was determined to be the zeroth/first reaction.
