“…Furthermore, the application of small organic compounds in optoelectronics is an emerging area that has been extensively investigated as this could lead to the development of more flexible and lower cost smaller devices e.g. solar cells, OLEDs, OFETs, OTFTs [31][32][33][34]. In this regard, heteroaromatic small molecules and hybrid compounds also have been largely investigated [35].…”

“…The proposed N,N-coordination of the Se center helps complete a chelation pocket in which there are both hard and soft donor atoms involved in metal ion coordination from the ligands (Figure 11). The detection limit for the palladium(II) ion was found to be 32 nM [48]. The report by Mafireyi et al discusses a probe in which the analyte is, in fact, a full protein.…”

In this review from literature appearing over about the past 5 years, we focus on selected selenide reports and related chemistry; we aimed for a digestible, relevant, review intended to be usefully interconnected within the realm of fluorescence and selenium chemistry. Tellurium is mentioned where relevant. Topics include selenium in physics and surfaces, nanoscience, sensing and fluorescence, quantum dots and nanoparticles, Au and oxide nanoparticles quantum dot based, coatings and catalyst poisons, thin film, and aspects of solar energy conversion. Chemosensing is covered, whether small molecule or nanoparticle based, relating to metal ion analytes, H2S, as well as analyte sulfane (biothiols—including glutathione). We cover recent reports of probing and fluorescence when they deal with redox biology aspects. Selenium in therapeutics, medicinal chemistry and skeleton cores is covered. Selenium serves as a constituent for some small molecule sensors and probes. Typically, the selenium is part of the reactive, or active site of the probe; in other cases, it is featured as the analyte, either as a reduced or oxidized form of selenium. Free radicals and ROS are also mentioned; aggregation strategies are treated in some places. Also, the relationship between reduced selenium and oxidized selenium is developed.

“…Soares-Paulino et al reported a selenium containing compound ( 138 ) (Scheme 25) for sensing of Pd 2+ in EtOH/water (1 : 1, v/v). 156 Upon binding with the metal ion, the compound exhibited an enhancement in absorption intensity at 565 nm and fluorescence intensity at 588 nm. The LOD for Pd 2+ was reported to be 32 ppb.…”
