Synthesis, photophysical properties, and theoretical studies on pyrrole-containing bromo Re(I) complex

Synthesis, Characterization, Fluorescence and Antibacterial Activity of the Re(VII) Complex [ReO3(phen)(H2PO4)]・H2O

“…These assignments are confirmed by the absorption spectra of free phen (Fig. 4a) and the results for related systems [24,25]. The energy gap (Fig.…”

Towards a core–shell composite structure loaded with a Ru-based sensing probe and its improved site-specific oxygen sensing performance

“…On the other hand, it appears that emissive metal complexes may satisfy requirements for an ideal sensing probe well [10][11][12][13][14][15][16][17]. Their emission is generally originated from triplet metal-to-ligand-charge-transfer (MLCT) excited state with lifetime as long as several microseconds, which is long enough for O 2 attack.…”

“…To properly combine sensing probe with supporting host, various hybrid structures have been proposed [11][12][13][14][15][16][17]. Among these candidates, core-shell structure has shown its virtues of easy-to-go construction [15][16][17][18][19]. However, an important factor for practical application, namely site-specific aggregation, is still underdeveloped for most oxygen sensing systems.…”

“…With this linear working curve, limit of detection(LOD) is determined as 5% following a literature method[12,22]. Compared to literature systems based on Ru(II), Cu(I) and Pt(II) complexes whose Stern-Volmer equations are usually non-linear ones, Ru@MCM-41@Core is superior to them by showing a linear working curve and high sensitivity[11,12,[15][16][17][18][19]. This improvement should be attributed to the homogeneous distribution of probe molecules in MCM-41 matrix in virtue of their covalent grafting with supporting framework.…”

On a magnetic-mesoporous silica molecular sieve loaded with a Ru(II)-complex: Construction, characterization and emission response to molecular O2

“…Aiming at synthesis simplification and performance optimization, various hybrid structures have been proposed. A few examples are core-shell, inner-hollow and Janus [13][14][15][16][17]. Core-shell structure has been considered promising since all components are tightly connected but still physically separated without compromising their individual feature.…”
