Achieving the adsorptive separation and chromatographic separation of industrially the important chemicals toluene and methylcyclohexane using the same material is a highly desirable goal. We have successfully accomplished this using a fluorinated macrocycle tetrafluoroterphen[3]arene (4FTP3), which was synthesized and used for gas chromatographic separation in our previous work. The macrocycle 4FTP3 permitted the adsorptive separation of toluene from a toluene/methylcyclohexane mixture (1 : 1, v/v) with a purity of 99.3 % in a single adsorption cycle. Additionally, the use of 4FTP3 as a gas chromatographic stationary phase permitted the high-resolution separation of a toluene/methylcyclohexane mixture, with a retention capacity decreasing in the order of: toluene>methylcyclohexane. Single-crystal structural analysis revealed that the C-H⋅⋅⋅F interactions between 4FTP3 and toluene resulted in an enhanced binding affinity, association enthalpy, and longer retention time for toluene. This macrocycle is of particular interest for use as a separation material due to its simultaneous adsorptive separation and gas chromatographic separation of toluene/methylcyclohexane. The present fluorinated macrocycle may therefore have roles to play in both analytical science and the chemical industry., (© 2025 Wiley-VCH GmbH.)

In-plane anisotropic two-dimensional (2D) semiconductors have gained much interest due to their anisotropic properties, which opens avenues in designing functional electronics. Currently reported in-plane anisotropic semiconductors mainly rely on crystal lattice anisotropy. Herein, AgCrP 2 S 6 (ACPS) is introduced as a promising member to the anisotropic 2D semiconductors, in which, both crystal structure and ion-electron co-modulations are used to achieve tunable in-plane conductance anisotropy. Scanning tunneling electron microscopy and polarized Raman spectroscopy show the structural anisotropy of ACPS. Electrical transport measurements show that its tunable in-plane conductance anisotropy is related to the ion-electron co-modulations, where Ag ion migration is anisotropic along a axis and b axis. Electrical transport measurements show the semiconducting properties of ACPS, as also supported by photoluminescence results. Moreover, the transfer curves of ACPS showcase large V g -related hysteresis, which is directionally controlled by anisotropic Ag ion migration. This work offers a possibility of using anisotropic charge transport in functional electronics by ion-electron co-modulations.
