Unless otherwise noted, all chemicals were purchased from commercial suppliers and used as received. Solvents were purchased from Merck. Reactions were monitored by TLC using UV light (254 nm). Chromatographic purification was performed using a Combiflash NextGen 300+ system (Teledyne Isco) using silica gel cartridges as the stationary phase and a hexane/ethyl acetate gradient as the mobile phase. The chromatographed materials were then recrystallized from the indicated solvent system, collected by filtration, and dried under reduced pressure. The materials were characterised by 1 H, 13 C{ 1 H} and, where appropriate, 19 F NMR. Electronic structure calculations were performed with the B3LYP hybrid functional and the LAN2DZ basis set in Gaussian G09 revision D01. Bimolecular PES scans employed additional GD3BJ dispersion and counterpoise correction terms. Following geometry optimisation we performed a frequency calculation, with the absence of imaginary frequencies taken to indicate the optimisation was at a minimum. We generated electrostatic potential (ESP) isosurfaces using the Gaussian formchk and cubegen utilities; the resulting cube files were then rendered using VMD. The interactions strength was quantified by performing a relaxed potential energy scan of the separation between two molecules arranged head-to-tail, from an initial separation of 2.5 Å to a maximum of 7 Å in 0.1 Å steps. Full experimental details, including synthetic procedures, structural characterisation and purity analysis are provided in the ESI.
