, 1970 On-Surface Synthesis of Nonmetal Porphyrins
Journal of the American Chemical Society, 2020We report the on-surface synthesis of a nonmetal porphyrin, namely, silicon tetraphenylporphyrin (Si-TPP), by the deposition of atomic silicon onto a free-base TPP layer on a Ag(100) surface under ultrahigh vacuum (UHV) conditions. Scanning tunneling microscopy provides insights into the self-assembly of the TPP molecules before and after Si insertion.

Reports on Progress in Physics, 1970
An account is given of some of the mechanisms which can lead to a transition from a metallic to a nonmetallic state, when a parameter such as the interatomic distance or temperature is varied. The simplest of these is the band overlap or Wilson transition, which occurs when a conduction band overlaps a valence band; this is discussed in § 2 and for ...

Phase diagram and thermal properties of organic analogues of nonmetal–nonmetal systems
Journal of Thermal Analysis and Calorimetry, 2015The solid–liquid phase equilibrium data on three binary organic systems, namely 4-hydroxy benzaldehyde (HB)–2-methyl-4-nitro aniline (MNA), 3-hydroxy-4-methoxybenzaldehyde (HMB)–2-chloro-4-nitroaniline (CNA) and 4-aminobenzophenone (ABP)–m-nitrobenzoic acid (NBA), determined by the thaw-melt method, show the formation of a eutectic at 0.60 mol fraction
