“…Похідні імідазолідин-4-ону, в тім числі і2-сульфаніліденімідазолідин-4-ону, володіють широким спектром цінних властивостей. Зокрема, протимікробні та протиракові властивості забезпечують перспективу їх застосування в медицині [1][2][3], тоді як здатність до інгібування корозії та наявність люмінесценції із солями Cu(I) та Cu(II) сприяють їх застосуванню у техніці та промисловості [4,5]. Також 2-сульфаніліденімідазолідин-4-они широко використовують в аналітичній хімії, зокрема, як реагенти у визначенні таких металів, як Pd(II), Cu(I), Cu(II), Ag(I) та Hg(II) [6][7][8].…”

“…6,7 Despite the small number of such representatives (according to the Cambridge Crystallographic Database only 12 copper coordination compounds with 2-thiohydantoin still known), 8 it was already investigated that they could have a potential interest as optical materials due to their fluorescence sensing properties and luminescence towards Cu + and Cu 2+ as well as the possibility of successful usage in crystal engineering of organometallics. 9,10 Moreover, previously, we have shown, that Cu(I) π-complexes with allyl derivatives of heterocycles can possess noticeable non-linear optical properties. [11][12][13][14][15] This work is the continuation of our previous studies, in which we have studied the coordination behavior of 3-allyl-2-thiohydantoin (Hath) regarding Ag(I), where obtained coordination compounds have already shown interesting structural peculiarities, confirming the status of 2-thiohydantoin-based molecules as the potential ligands in the structural engineering.…”

The present work is directed toward preparation and structural characterization of two novel Cu(I) arylsulfonate π-complexes with 3-allyl-2-thiohydantoin, namely [Cu2(Hath)4](C6H5SO3)2 (1) and [Cu2(Hath)4](p-CH3C6H4SO3)2 · 2H2O (2) (Hath = 3-allyl-2-thiohydantoin), obtained by the means of alternating current electrochemical synthesis and studied with X-ray diffraction method. In both structures, the inner coordination sphere is represented by the cationic dimer [Cu2(Hath)4]2+ with one crystallographically independent copper(I) atom which has a trigonal pyramidal coordination environment formed by three Hath thiogroup S atoms and double C=C bond of its allyl group. [Cu2(Hath)4]2+ fragments in both coordination compounds are very similar, despite some divergences such as a big difference in Cu−S distance to the apical S atom (3.0374(8) Å in 1 and 2.7205(9) Å in 2). This difference was explained by the impact of the system of weak interactions, which are quite different.

“…The fluorescent probe detection method is portable and easy to operate, which can solve the above problems. However, the detection probe designed in the early stage is mainly used to detect cuprous ions [24][25][26] in the environment, so it is very important to design a fluorescent probe for measuring Cu(I) under physiological reducing conditions.…”

Cuprous ion is an essential element for human life activities. However, excessive cuprous can cause dysfunction of the human body system. To help explain this evolving biology, we report a fluorescent probe for the detection of unstable Cu(I). Cu(I) undergoes a metal complexation reaction with the sulfur element in the probe, resulting in a photoelectron transfer (PET) effect. The fluorescence of the probe is greatly suppressed, and the rapid and selective visual detection of Cu(I) in the inorganic environment is realized. And there is a good linear relationship between the probe fluorescence intensity and Cu(I) concentration (R 2 =0.992), which can realize the quantitative detection of Cu(I). When the probe concentration is 0.1 μM, the detection limit is 15 nM, and the detection limit of the visual method is as low as 0.1 μM. This work provides a valuable starting point for real-time monitoring of Cu(I) concentration
