WebJan 1, 2024 · The experimentally synthesised diamond nanothreads are analogue to polymer I, which is a combination of tube (3, 0) (structure 123456 in Figure 7.1) and the so-called Stone–Wales (SW) transformation defects (structure 135462 in Figure 7.1). WebTwo-dimensional 13C–13C NMR spectra showing bonding between chemically nonequivalent sites rule out enumerated single-site thread structures such as polytwistane or tube (3,0) but are consistent with multisite degree-6 nanothreads. Approximately a third of the carbon is in “degree-4” nanothreads with isolated double bonds.
WebMay 29, 2024 · Approximately a third of the carbon is in “degree-4” nanothreads with isolated double bonds. The presence of doubly unsaturated degree-2 benzene polymers can be ruled out on the basis of 13 C– 13 C NMR with spin exchange rate constants tuned by rotational resonance and 1 H decoupling.
