“…32 Another popular method for producing these compounds involves the reaction of a halogenated arene (Scheme 1b) with an alkali-metal dichalcogenide prepared in situ from equimolar mixtures of chalcogen and sodium in an aprotic polar solvent, such as N, N-dimethylacetamide (DMA), 1,3-dimethyl-2-imidazolidinone (DMI), or DMF. For example, tetraselenonaphthalene (2), 34 tetrachalcogenotetracenes (11, 13 and 14), [35][36][37] tetrachalcogenoanthracenes (3-6), 6,[38][39][40][41] tetrachalcogenophenanthrenes (7 and 8) 42 were prepared by this reaction route. However, there are still limitations regarding this kind of reaction.…”

“…58 For 13, the molecules crystallize in centrosymmetric space group with a nearly planar structure. 37 Along the c-axis, the molecules form uniform stacks with an interplanar distance of 3.42 A ˚. However, compared to the stacks of 12 with sulfur cyclic rings facing to each other, the stacks of 13 are closely packed in such a way that the selenium cyclic rings do not pack face-to-face.…”

“…In order to proceed beyond simple tests and demonstrations of principle, we observed the EPR spectrum of polyaniline, a conducting polymer, prepared in the laboratory of Professor Khidekel at Chernogolovka. 30 The property of polyaniline that makes it intriguing for FIR-EPR studies is that there is significant exchange narrowing of the polyaniline FIR-EPR spectrum possibly mediated by polarons. 10 Spectra at 170 and 250 GHz were taken to elucidate the exchange-narrowing effect on the line shape.…”

“…Solid organic compounds on the other hand are considered as amorphous materials with poor conductivity. In order to develop conducting materials based on organic compounds chemists have recently explored charge‐transfer salts and polymeric hydrocarbons [ 1 ] mostly from planar molecules so that they can lead to anisotropic structures having pseudo‐one‐dimensional electronic properties. [ 2–11 ] The tetracyano‐p‐quinodimethane (TCNQ)–tetrathiafulvalene (TTF) was amongst prominent design strategies with very high conductivity of 500 Ω cm −1[ 1,12 ] as compared to metallic silver 630 000 Ω cm −1 at room temperature.…”
