Chen, Xiaoyu Zhang, Li Yao, Shenxin Tan, Gengwen Wang, Xinping Controlling the Conductivity of Oligomer Radical Cations by Tuning Stacking Structures of π‑Dimers Salts containing radical cations of dialkoxyterphenyls (DP) including 4,4′-dimethoxyterphenyl (<b>1</b>) and 4,4′-diethoxyterphenyl (<b>2</b>) have been isolated with weakly coordinating anions [Al­(OR<sub>F</sub>)<sub>4</sub>]<sup>−</sup> (OR<sub>F</sub> = OC­(CF<sub>3</sub>)<sub>3</sub>) or [Al­(OR<sub>Me</sub>)<sub>4</sub>]<sup>−</sup> (OR<sub>Me</sub> = OC­(CF<sub>3</sub>)<sub>2</sub>CH<sub>3</sub>) as the counterions. The radical cation salts have been characterized by single-crystal X-ray diffraction analysis, UV–vis absorption, and electron paramagnetic resonance spectroscopy, as well as conductivity measurements. Single-crystal structures indicate that the radical cations assemble into infinite stacks of π-dimer in these salts, while single-crystal conductivity measurements show that the conductivity of the salts is significantly affected by substituent groups and the interaction among the cation, anion, and solvent. single-crystal conductivity measurements show;substituent groups;DP;resonance spectroscopy;Single-crystal structures;cation salts;Oligomer Radical Cations;Tuning Stacking Structures;π- dimer;2 CH 3;single-crystal X-ray diffraction analysis;conductivity measurements;anion;UV;OC;Al 2019-08-07
