“…A landmark feature is that the nanoconfined ionic layers form internal 2D crystalline order even at 150 °C (see Figure d), and the material is still able to flow (see Figure S27, Supporting Information). Related seemingly contradicting combination of 2D‐crystalline nanoscale order in smectics and simultaneous flow has been observed previously in rare cases and is here supported by the molten di‐ n ‐alkyl tails (see Figure S28, Supporting Information) …”

Materials involving nanoconfinement of ionic liquids (ILs) have been pursued for functionalities and ionic devices. However, their complex synthesis, challenges to achieve long-range order, and laborious tunability limit their practical implementation. Herein, these challenges are addressed by complexing surfactants to ILs, yielding a facile, modular, and scalable approach. Based on structural screening, ionic complexation of di-n-nonylamine to the terminal sulfonic acid of 1-(4-sulfobutyl)-3-methylimidazolium hydrogen sulfate IL is selected as a proof of concept. Spontaneous homeotropic smectic order over micrometers is observed, with alternating ionic and alkyl layers. The 1 nm thick ionic layers involve 2D crystalline internal order up to 150 °C, strongly promoting anisotropic ion transport (σ || /σ ⊥ > 6500), and curiously, still allowing fluidity. High ionic conductivity of 35 mS cm −1 and mesoscopic diffusion coefficient of ≈10 −5 cm 2 s −1 at 150 °C along the ionic layers are observed. Fast anisotropic ion transport by simply complexing two components open doors to functional materials and applications.

“…Specifically, industrial phenolic by-products, dyes, and pigments constitute some representative examples of such water contaminants, whose increased solubility in water, along with their high resistance to common degradation practices, make their removal from water environments a rather complex, costly, and time-consuming process. Some of the most popular techniques for eradicating these color substances from water are adsorption [12], photocatalysis [13], membrane technology [14], chemical oxidation [15], biological degradation, and coagulation [16,17]. The first and second categories are the most employed methods due to their operational simplicity and non-toxic nature.…”

Radially polymerized dendritic compounds are nowadays an established polymer category next to their linear, branched, and cross-linked counterparts. Their uncommon tree-like architecture is characterized by adjustable internal cavities and external groups. They are therefore exceptional absorbents and this attainment of high concentrations in their interior renders them ideal reaction media. In this framework, they are applied in many environmentally benign implementations. One of the most important among them is water purification through pollutant decomposition. Simple and composite catalysts and photo-catalysts containing dendritic polymers and applied in water remediation will be discussed jointly with some unconventional solutions and prospects.
