Two supramolecular ionic nanomaterials (SINs) were successfully prepared by multidentate imidazolium organic salts and multidentate acid via ionic self-assembly (ISA), which is formed by tetraphenylethylene (TPE)-based organic salts (TPE-COS and TPE-C16OS) and 4,4′,4″,4‴-(ethene-1,1,2,2-tetrayl)tetrabenzenesulfonic acid (TPE-SO3H) in MeOH. These SINs exhibited high thermal stability and are insoluble in solvents. Furthermore, as fluorescence sensors, they showed high sensitivity and selectivity in the detection of nitroaromatic explosives, especially for trinitrophenol (TNP); the linear range of SIN-1 and SIN-2 was 0.4–128 μM and 1–128 μM; their λex was set as 340 and 350 nm; λem was 489 and 458 nm; and the related limit of detection was 0.87 and 0.42 μM, respectively. The quenching mechanism of TNP for SINs is the synergistic effect of the energy transfer, the inner filter, and photoelectron transfer.

A series of triphenylene (TP) compounds—denoted 3,6-THTP-DiCnOH—bearing four hexyloxy ancillary chains and two variable-length alkoxy chains terminally functionalized with hydroxyl groups have been synthesized and characterized. The shorter homologs revealed mesogenic characteristics, giving rise to thermotropic mesophases in which π-stacked columns of H-bound dimers self-organize yielding superstructures. Molecular-scale models are proposed to account for their structural features. The three studied compounds yielded supramolecular gels in methanol; their ability to gelify higher alcohols was found to be enhanced by the presence of water. The intermediate homolog also gelled n-hexane. Compared to their isomeric 2,7-THTP-DiCnOH analogs, the 3,6-derivatives showed a higher tendency to give rise to LC phases (wider thermal ranges) and a lower organogelling ability (variety of gelled solvents, lower gels stabilities). The overall results are analyzed in terms of different kinds of competing H-bonds: intramolecular, face-to-face dimeric, lateral polymeric, and solvent–TP interactions.
