Synthesis and tunability of highly electron-accepting, N-benzylated "phosphaviologens"
Stolar, Monika,Borau-Garcia, Javier,Toonen, Mark,Baumgartner, Thomas
, p. 3366 - 3371 (2015)
We report a structure-property study on phosphoryl-bridged viologen analogues with a remarkably low reduction threshold. Utilizing different benzyl groups for N-quaternization, we were able to confirm the p-benzyl substituent effect on the electronic tuna
Photochromism of Viologen Crystals
Kamogawa, Hiroyoshi,Suzuki, Tsuyoshi
, p. 794 - 796 (1987)
Some viologen crystals bearing a p-toluenesulfonate anion as a counter ion were shown to exhibit reversible photoreductions (photochromism) either in air or under vacuum, whereas in a poly(N-vinyl-2-pyrrolidone) matrix all investigated viologens indicated reversible photocolor developments.Amphoteric ions such as 1,1'-bis(3-sulfonatopropyl)-4,4'-bipyridinium also developed colors with high stabilities.
Targeted synthesis of ionic liquid-polyoxometalate derived Mo-based electrodes for advanced electrochemical performance
Chen, Guojian,Zhang, Lei,Zhang, Yadong,Liu, Ke,Long, Zhouyang,Wang, Ying
, p. 7194 - 7201 (2019)
Rational design of advanced electrode materials with high capacity and long cycle stability is a great challenge for both lithium and sodium storage. In this work, we report a versatile strategy for the synthesis of N/P-codoped MoO2@carbon (N/P
Substituent-Modulated Assembly Formation: An Approach to Enhancing the Photostability of Photoelectric-Sensitive Chalcogenide-Based Ion-Pair Hybrids
Lin, Jian,Fu, Zhixing,Zhang, Jiaxu,Zhu, Yujia,Hu, Dandan,Li, Dongsheng,Wu, Tao
, p. 3119 - 3122 (2017)
A series of electronically active viologen dications (RV) with tunable substituent groups were utilized to hybridize with [Ge4S10]4- (T2 cluster) to form the hybrids of T2@RV. These hybrids exhibited variable supermolecula
Metal-free reduction of unsaturated carbonyls, quinones, and pyridinium salts with tetrahydroxydiboron/water
Li, Tiejun,Peng, Henian,Tang, Wenjun,Tian, Duanshuai,Xu, Guangqing,Yang, He
, p. 4327 - 4337 (2021/05/31)
A series of unsaturated carbonyls, quinones, and pyridinium salts have been effectively reduced to the corresponding saturated carbonyls, dihydroxybenzenes, and hydropyridines in moderate to high yields with tetrahydroxydiboron/water as a mild, convenient, and metal-free reduction system. Deuterium-labeling experiments have revealed this protocol to be an exclusive transfer hydrogenation process from water. This journal is
The Host-Guest Properties Observed between the Viologens and Cyclopentanocucurbit[6]uril
Cheng, Si-Yuan,Qu, Yun-Xia,Tao, Zhu,Zhou, Kai-Zhi,Wei, Lian-Tong,Wang, Cong,Zhao, Wei-Wei,Jiang, Dao-Fa,Ma, Pei-Hua

The interactions between cyclopentanocucurbit[6]uril (abbreviated as CyP6Q[6]) and a series of dialkyl-4,4′-bipyridinium and diaryl-4,4′-bipyridinium dicationic guest molecules, where the alkyl group is CH3(CH2)n with n = 0-6 (expressed as G1 to G7) and the aryl group is phenylene (G8) and xylene (G9), have been investigated in aqueous solution using 1H NMR spectroscopy, isothermal titration calorimetry (ITC), and electronic absorption spectroscopy. Our results show that G1 and G2 form 1: 1 host-guest inclusion complexes with CyP6Q[6], in which the bipyridinium core is partially embedded in the cavity of CyP6Q[6]. G3-G9 form 2: 1 dumbbell-type host-guest inclusion complexes, in which the substituents are encapsulated by CyP6Q[6]. At the same time, CyP6Q[6] was compared with several other cucurbit[n]urils (Q[n]s) and their derivatives, such as Q[6], Q[7], and TMeQ[6], which have been reported to interact with this type of guest molecule. In its binding mode, CyP6Q[6] shows many interesting and different properties, and this difference was mainly reflected with G1 and G2.
