“…This is also an excellent electron donor that was extensively used for the design of push-pull dyes developed for different applications in organic electronics such as energy conversion [198][199][200][201][202][203][204][205][206][207][208][209][210], light-emitting materials for organic light-emitting diodes (OLEDs) [211][212][213][214][215][216][217][218][219][220][221][222][223] or semi-conductors for organic field effect transistors (OFETs) [199,[224][225][226][227][228][229]. Phenothiazines were also developed as fluorescent probes for the detection of various molecules and ions in organic and aqueous solutions, food, live cells and animals [230][231][232][233][234][235][236][237][238][239][240]. In 2021, Yagci and coworkers proposed a phenacyl phenothiazinium salt (P-PTh) exhibiting a panchromatic absorption (see Figure…”

During the last decades, multicomponent photoinitiating systems have been the focus of intense research efforts, especially for the design of visible light photoinitiating systems. Although highly reactive three-component and even four-component photoinitiating systems have been designed, the complexity to elaborate such mixtures has incited researchers to design monocomponent Type II photoinitiators. Using this approach, the photosensitizer and the radical/cation generator can be combined within a unique molecule, greatly simplifying the elaboration of the photocurable resins. In this field, sulfonium salts are remarkable photoinitiators but these structures lack absorption in the visible range. Over the years, various structural modifications have been carried out in order to redshift their absorptions in the visible region. In this work, an overview of the different sulfonium salts activable under visible light and reported to date is proposed.

For the efficient detection of Hg 2+ and ClO − , a double-analyte-responsive fluorescent probe PTB was successfully synthesized by combining N-butyl-3-formyl phenothiazine with hydrazine benzothiazole, and designing a specific reaction site for recognizing two analytes (Hg 2+ and ClO − ) in a compound. It was shown that probe PTB successfully formed a stable complex with Hg 2+ in the coordination ratio of 2 : 1 by using the strong sulfur affinity of Hg 2+ , which resulted in a remarkable "turn-off" effect, with a quenching efficiency of 92.5 % and four reversible cycles of Hg 2+ fluorescence detection. For the fluorescence detection of Hg 2+ , the response time is fast (≤ 2 min) and the detection limit is low (7.8 nM), showing extremely high sensitivity, and the performance is obviously better than that of the reported fluorescent probes for detecting Hg 2+ . In particular, probe PTB has low toxicity and good biocompatibility, and has been successfully used for imaging of Hg 2+ in living cells. Moreover, probe PTB uses thioether bond and carbon-nitrogen double bond as reaction sites to detect ClO − , which has large Stokes Shift (149 nm), good selectivity, high quenching efficiency (96.5 %) and fast time response (about 10 s), and successfully detects ClO − in actual water samples.

“…The quest for developing a selective and highly sensitive fluorescent sensor/sensing material for different transition metals has led the scientific community to screen a large variety of organic structural features, of which phenothiazine has been the most explored. Phenothiazine-based fluorescent sensors have been most applied for the detection of heavy metals, especially mercury (Hg 2+ ). ,, In recent years, its effectiveness has also been tested for the selective fluorescence detection of CN – and F – . − However, the number of examples of phenothiazine-based fluorescent sensors for selective Cu 2+ detection is fewer and certainly presents an opportunity to develop more effective phenothiazine-based fluorescent molecules for biological application.…”

Sensing important metals in different environments is an important area and involves the development of a wide variety of metal-sensing materials. The employment of fluorescent sensors in metal sensing has been one of the most widely applied methodologies, and the identification of selective metal sensors is important. We herein report a phenothiazine-based Cu(II) fluorescent sensor that is highly selective to Cu(II) ions compared with other transition metal salts. The Lewis acidity of the Cu(II) salt certainly was found to be a factor for obtaining an enhanced sensing response in MeOH as the solvent, while a ratio of 1:1 was calculated to be the most optimum for getting the desired response.
