Ultrasound-assisted synthesis of organotin compounds and their application as luminescent dye in silk fibroin scaffolds

Recent advancements of fluorescent tin(iv) complexes in biomedical molecular imaging

“…19,23 The presence of the –OH group in the ligand scaffold sometimes shows inter- and intra-molecular H-bonding which could also influence the fluorescence properties of organotin complexes. 18 Fascinatingly, a group reported that the fluorescence quantum yield of a complex strongly enhanced after the change in the fluorophore from benzene to naphthalene. 11 In short, since molecules fluoresce by conjunction, and the substituents of their ligands (electron-withdrawing and electron-donating) show a big correlation to their emission peaks.…”

“…As well as having these luminescence properties, tin metal complexes are relatively simple to synthesize, easy to use, environmentally friendly, and more economical than other metal complexes. There is growing evidence that fluorescent tin and organotin complexes are effective in the fields of photonics, 9 optoelectronics, 10 and biomedical applications, such as organic light-emitting diodes (OLEDs), 11 in vitro sensing of ions, 12–16 silk fibroin staining, 17–19 in vitro imaging by laser scanning confocal microscopy, and two-photon laser scanning fluorescence microscopy in tissues, and living animals. 8,10…”

Silk: history, obtaining, structure and properties of an old material in the development of new technologies

“…2,4,6 In this context, silk fibroin has been increasingly explored due to its elasticity properties, mechanical resistance, controlled biodegradation, and biocompatibility. 4,[189][190][191][192][193][194][195][196] The most reported tissues for potential regenerative treatments using fibroin-based materials, whether pure or in the presence of other compounds, 153 are bone (36%), [145][146][147][148][149][150][151][152][153][154] cartilaginous (17%), [197][198][199][200][201][202][203] vascular (10%), 102,113,[141][142][143][144] and cutaneous (5%) tissues, [155][156][157][158] as well as cornea (2%) [136][137][138][139][140] , as described by Kasoju and Bora in 2012. 189 Compared to other types of tissues, fibroin has been mostly e...…”

Dinuclear Organotin Building Blocks and their Conversion into a Tetranuclear Macrocycle Containing Sn−O−Sn Linkages

“…[11,[24][25][26][27] Being Lewis acids, four-coordinate tin compounds count on the possibility of coordination number increase, enabling linkages with other compounds, e. g. solvent or guest molecules. [28] Because of these attributes, organotin compounds with interesting properties concerning the catalysis of transesterification and CÀ C coupling reactions, [29][30] anion and molecular recognition, [31][32][33][34][35] materials chemistry, [36][37][38] or biological activity [39][40][41][42] have been developed.…”
