“…Usually, this effect is observed by 1 H and 13 C NMR spectroscopic analysis of the olefinic and methylenic groups of the cycle. In complex 9 ‐G M1 ′, this asymmetry is also observed for the phosphorus atoms at the 8th and 10th bonds of the olefinic groups, illustrating the high sensitivity of 31 P NMR spectroscopy to subtle modifications in the environments of phosphorus atoms, as some of us have previously reported 13b,20…”

“…Second, a classic Abramov-type reaction is undertaken with 8 in presence of dimethylphosphite in a concentrated THF solution, which leads to the desired compound 9 with two a-hydroxyphosphonates on the surface. [21] Finally, 1 H NMR spectroscopy and TLC were used to ascertain the purity and the absence of residual impurities. Moreover, compounds were subjected to flash column chromatography when possible during the synthesis to remove impurities.…”

New hybrid optical sensors have been prepared by grafting specifically designed fluorescent, functionalised, phosphorus-containing dendrimers onto a nanocrystalline mesoporous titania thin film formed by evaporation-induced self-assembly. The structural characterisation and optical behaviour of these new fluorescent probes have been studied both in solution and after being grafted onto an inorganic network, which resulted in the discovery of improved probing selectivity in the solid state. This new hybrid sensor exhibits high sensitivity to phenolic OH moieties (especially those from resorcinol and 2-nitroresorcinol), which induce the quenching of fluorescence more efficiently in the solid state than in solution. This effect is a result of the increased spatial proximity of the fluorescent molecules, which is induced by pore confinement that makes the formation of hydrogen bonds between the hydroxyl moieties of the quenchers and the carbonyl groups of the dendrimer easier.

“…With the diphosphino end groups, various organometallic derivatives of transition metals are grafted, such as ruthenium (compound 16-G n ) [33], palladium (compound 17-G n ) (Scheme 6), platinum, or rhodium [34]. NH 2 -terminated dendrimers of type 6b-G n or others [35] are used also in condensation reactions with various aldehydes [36].…”
