Organo-sulfur molecules enable iron-based battery electrodes to meet the challenges of large-scale electrical energy storage

“…In our previous study of alkanethiols, we found that besides the interaction of the sulfur atoms in the head group with the iron surface, the inter-chain interactions resulting from van der Waals forces and non-bond interactions made a signicant contribution to the stabilization of the adsorbed layers. 22,[27][28][29][30] Also, with the various molecular classes studied here, the geometric factors were also signicant (Table 3). 31 Substantial changes in charge-transfer resistance resulted with the addition of long-chain alkanethiols (dodecanethiol and octanethiol), the aromatic thiols (benzenethiol and 2-methylbenzenethiol), the short-chain dithiol (1,2-diethanethiol) and the small cyclic ether (1,4-dithiane).…”

Dipole-induced structure in aromatic-terminated self-assembled monolayers—A study by near edge x-ray absorption fine structure spectroscopy

“…Because of the trans-conformation of the methylene units along the alkyl chain, each alkanethiol occupies an area of about 24 Å 2 ͑5.6 Å in diameter͒. 27 Since the longest distance across the facet of a benzene ring is about 5.0 Å, we assume that the aromatic rings experience little steric hindrance from neighboring alkanethiol molecules in the SAM, and hence possess a high degree of rotational freedom ͑rotation about ␤͒.…”

Electrochemical investigations on stability and protonation behavior of pyridine-terminated aromatic self-assembled monolayers

“…11,12 Enhanced lateral chain-chain interaction between aromatic thiol molecules results in formation of highly compact rigid SAMs 13,14 and makes them excellent barriers against metal ion penetration in electrolytic media. 15 Properties of SAMs are often tuned by attaching functional termination groups on the molecular chain such as -SH, 16,17 -OH, 2,18 -COOH, 4,19 -SO 3 H, 20 -CN 20,21 and -NH 2 [22][23][24] for appropriate technical applications. A pyridine moiety as a functional group makes these films interesting for a variety of applications.…”
