The reaction of propene with difluorosilylene

Development of a fluoride-anion sensor based on aggregation of a dye-modified polyhedral oligomeric silsesquioxane

“…The appearance of the new peak at −117 ppm indicated Si–F bond formation according to the reports on POSS-based fluoride sensors. 30,32 From the chemical shift of compounds reported in previous studies (Table S2, ESI†), 42,43 the chemical structure of this new peak was expected to be the decomposition product D1 . Although generation of D1 requires multiple fluoride anions, the fluorescent enhancement induced by release of aggregation can be observed even in 3 μM of TBAF (1.5 equiv.)…”
