Wang, Ren-Tzong published the artcileAnion-induced ionic liquid crystals of diphenylviologens, SDS of cas: 47369-00-6, the publication is Journal of Materials Chemistry C: Materials for Optical and Electronic Devices (2018), 6(35), 9430-9444, database is CAplus.
Two series of ionic liquid crystals derived from diphenylviologens, I and II, were prepared and their photophys. and electrochem. properties were also investigated. The crystallog. data of two single crystals, I (R = CnH2n+1, n = 10) and II-BF4 (R = CnH2n+1, n = 12), showed that a mono- or bilayer-lamellar structure was induced by intermol. H-bonds. All mesophases were identified as smectic A phases by POM textures and powder XRD data. A linear correlation plot (R2 = 0.8885) of the d-spacings vs. the calculated effective radius (Reff) in compounds II was obtained. The aggregation-induced emission (AIE) ranging from ca. 463 to 529 nm observed in compounds II (e.g., X = BF4, PF6, RSO3, OTf and NTf2) was also anion dependent. Also, compounds II exhibited thermal switching, with an On/Off-emission mode between the Cr and SmA phases. In its cyclic voltammogram, compound I-RSO3 (R = CnH2n+1, n = 12) exhibited two distinct reversible redox couples; in contrast, compound II-RSO3 (R = CnH2n+1, n = 12) formed spike-like voltammetric peak potentials without redox couples.
