A multifunctional organogel polyelectrolyte (PVA/PTA/CoCl 2 ) is developed comprising the poly(vinyl alcohol) (PVA), terephthalic acid (PTA), and cobalt chloride (CoCl 2 ). PVA and PTA were cross-linked by the esterification reaction at 120 °C in DMSO and could take shape a steady polymer gel, which accomplished a combination of high tensile, mighty mechanical obdurability, good self-healing, great ionic conductivity, and robust self-adhesiveness. Furthermore, activated carbon based supercapacitor with PVA/PTA/CoCl 2 organogel electrolytes delivers high specific capacitance at high scan rates, and CV curves are close to ideal, while exhibiting excellent stability and durability of physical deformation after bending-release cycling, respectively.

A multifunctional antifreezing mechanically tough conductive organogel polyelectrolyte was designed and prepared by simultaneously introducing poly(vinyl alcohol), tripentaerythritol, and H2O/dimethyl sulfoxide (DMSO) binary solvent. Based on the outstanding freeze resistance of the H2O/DMSO binary solvent, this organogel showed good mechanical properties and long-term stability in the temperature range of −20 to 20 °C. Meanwhile, the as-prepared flexible supercapacitor exhibits superior electrode specific capacitance (140 F g–1), high ionic conductivity (18.9 mS cm–1), outstanding cycling stability (only 5% capacitance decay over 2000 cycles), and excellent durability (85% weight retention after storing for 10 days) even at a low temperature of −20 °C. In addition, the prepared organogel exhibits tunable optical performances in diverse polar solvents and could act as information storage installations for recording and wiping.

We have designed and constructed two artificial light-harvesting systems (ALHSs), which are based on the supramolecular self-assembly of acylhydrazone functionalized quinoline (L), Al 3 + and fluorescent dyes. The L-Al 3 + supramolecular assembly distinctly improved aggregation-induced emission enhancement and served as a donor for ALHSs. Acridine yellow and acridine orange were found to be good acceptors to realize the energy transfer process with good efficiency.

A method for preparing new artificial light-harvesting systems (ALHSs) based on supramolecular metallogels was proposed. Various metal ions were introduced into a solution of a bi-benzimidazole compound (P) in ethylene glycol, and P exhibited high selectivity toward Al 3+ , as indicated by the noticeable red shift (49 nm) observed in the fluorescence spectra of P after the addition of Al 3+ . Interestingly, the gelator, P, could self-assemble into a stable supramolecular gel (P-gel) that exhibits strong aggregation-induced emission in ethylene glycol. Thus, two ALHSs were successfully prepared in a gel environment. The P−Al 3+ assembly acts as the donor in the ALHSs, while BODIPY 505/ 515 (BDP) and rhodamine 6G (Rh6G), which are loaded onto the P−Al 3+ assembly, act as acceptors. In these two diverse systems, the occurrence of an energy transfer process is confirmed from the P−Al 3+ assembly to BDP and Rh6G. The findings of this study will enable the design and fabrication of ALHSs.
