orientation adsorption
1.At 350 K for ~ 2L exposures, the results revealed that the orientation dependence of the adsorption oxygen amount is comparatively weak, and it ean be understood in terms of step-enhanced adsorption.
3.Compared with DPU, the conjugate extent of N atom of secondary amine group in DPTU is greater than that in DPU, which leads to the adsorption of DPTU in parallel orientation by the p?π?electron interaction of the aromatic ring.
