“…Tomioka et al [18] reported that chemically synthesized 2,3-diphenyl-2, 3-dihydrofuran has a similar pattern in the same region. In the proton NMR spectra, both poly(4HS) and poly(NOHS) showed indistinguishable broad peaks at 6 to 8 ppm in the aromatic region that are characteristics of different and closely packed hydrogens as polymer formed.…”

“…Numerous studies have shown that if the ground state of carbenes is triplet, then the efficiency of carbene transformations by the `abstraction ± recombination' mechanism (4) in the transition from the liquid to the solid phase with a decrease in temperature is drastically increased. 38,43,44 The effective constants of the decay rate of triplet carbenes determined experimentally at cryogenic temperatures are very small. For example, they amount to 10 73 ± 10 74 s 71 for different frozen organic matrices (Ref.…”

Overlayers of a fatty acid (palmitic and lauric acid) formed at the interface between a solution of this molecule in phenyloctane and the basal plane of graphite are studied by in situ scanning tunnelling microscopy. The layers organize into lamellae, which are formed by a close packing arrangement of molecules parallel to the graphite surface. Chemical modification of the STM tips used allowed identification of the functional group. Indeed, the gold tips used are functionalized with 4-mercaptobenzoic acid (4-MBA) and 4-mercaptotoluene (4-MT). The same functional group on a sample is then 'seen' as a dark and a bright spot when imaged with 4-MBA and 4-MT modified tips, respectively. This contrast distinction is related to interactions (or a lack of them) between the carboxyl group on the sample and molecules on the tip, which can facilitate (or hinder) the electron tunnelling.
