In this study, perfluoroalkylated derivatives of benzoic acid S-6 and O-6 were designed and synthesized as supramolecular gelators using a simple one-step method. Both S-6 and O-6 could form gels in various organic solvents. Notably, these compounds have potential applications in environmental remediation, with S-6 demonstrating significant promise for oil spill treatment. After five recycling cycles, the recovery rate of the gelation capacity for diesel oil remained above 90%. Xerogels derived from O-6 at a concentration of 5 wt% in pump oil effectively adsorbed Rhodamine B (RhB). The adsorption process primarily involved chemical adsorption, electrostatic interactions between the O-6 xerogel and the cationic RhB dye, as well as physical adsorption within the xerogel's pores. In summary, benzoic acid derivatives represent a kind of multifunctional, recyclable, and efficient materials.

The activation of hair follicle dermal papilla cells (HFDPCs), a critical target of hair loss relief, can be achieved through the upregulation of proliferation, the stimulation of hair inducibility, and the inhibition of cellular senescence. Veratric acid (VA) is a major benzoic acid found in fruits and vegetables. The biological activity of VA on HFDPCs remains to be elucidated.

Molecular design strategies such as noncovalent conformational locks, self-assembly, and D-A molecular skeletons have been extensively used to devise efficient and stable hole transport materials. Nevertheless, most of the existing excellent examples involve only single or dual strategies, and triple strategies remain scarcely reported. Herein, we attempt to develop two quinoxaline-based hole transport materials ( and ) through a triple strategy encompassing an S···N noncovalent conformational lock, D-A molecular skeletons, and self-assembly or conjugate engineering.
