Recent reports describe the different products resulting from the reaction of C60 with benzyne generated from anthranilic acid derivatives and isoamyl nitrate in the presence and absence of triethylamine. Reinvestigation here via 1H, 13C, HMBC NMR and Mass spectroscopy elucidates that these products are the [6,6] closed C60-fused δ lactones, and not the [5,6] open fulleroids which would result from...
Bicyclic dioxetanes, 1-(hydroxyaryl)-2-aza-6,7-dioxabicyclo[3.2.0]heptanes, bearing a syn-N-acyl or anti-N-acyl group underwent TBAF (tetrabutylammonium fluoride)-induced decomposition in DMSO or THF accompanied by the emission of bright light, the maximum wavelengths (λmaxCL) of which were similar to each other. On the other hand, upon treatment with t-BuOK in THF, the dioxetanes bearing a syn-N-acyl...
The photopolymerization of various mesogenic methacrylates (MEMs) by using an aluminium porphyrin complex (MTPP) as a photocatalyst has been investigated to show that the resulting polymers are living in nature. The polymerization of 6-[4-(4-cyanophenylazo)phenoxy]hexyl methacrylate (MAC) was exceptionally slow when compared to other mesogenic methacrylates, such as those containing ester and/or...
