Summary: We synthesized and characterized a new Cu-Salphen compound, which acted as a Lewis acid to host guest anions in two different forms: a) free molecule, and b) copolymerized with protective co-monomers. Higher amounts of Cu-Salphen resulted in larger and more homogeneous polymer sizes. The polymer size, along with other factors such as glass transitions, heat capacity, thermal degradation, and host-guest species distribution, explained significant enhancements in the host's binding site.

Summary: In this study, the synthesis and crystallographic characterization of a new Cu-Salphen compound and its use as a Lewis acid against guest anions were described. It was found that higher contents of Cu-Salphen resulted in larger and more homogeneous polymer sizes. The growth of the host's binding site was explained by factors such as polymer size, glass transitions, heat capacity, thermal degradation, guest-saturation degrees, and host-guest species distribution profiles. Spectrofluorimetry measurements showed that Cu-Salphen had larger blue-shifted luminescence in the polymers compared to the non-polymerized counterpart, and enhanced fluorescence upon guest association. A cooperative incorporation of the guests into the internally protected binding site pockets in the random coil polymer conformations was proposed.

Summary: A simple biphenyl bis-amidinium compound (1.Cl-2) can selectively precipitate sulfate from water even at low concentrations. It shows complete selectivity against monovalent anions and high selectivity even against CO32- and HPO42-. It is highly effective in removing sulfate (>90%) from both seawater and highly acidic conditions relevant to mining waste-streams. X-ray crystallography reveals the structure of 1.SO4 with tightly packed, anhydrous arrangement where each sulfate anion receives eight hydrogen bonds from amidinium N-H hydrogen bond donors.

Summary: Pillarenes, with their useful features such as rigidity, capaciousness, hydrophobic cavities, and exposed functional groups, have become increasingly popular since their discovery in 2008. This Minireview focuses on the use of functionalized Pillarenes and their assembled supramolecular materials in catalysis, providing insights into their mechanisms and potential applications. Subdivided topics include catalysis promoted by the Pillarene rim/cavity, Pillarene-based nanomaterials, and Pillarene-based polymeric materials, making it the first comprehensive overview on Pillarene-based catalysis.

Summary: Macrocycle engineering is a key topic in supramolecular chemistry. This study combines different approaches and post-synthetic modifications to transform a single tether into multiple rings. The macrocycles undergo redox reactions, allowing for control of conformational changes and host activity, enabling the capture and release of guests, ring transformations, and control of pseudorotaxane-to-pseudorotaxane conversions.

Summary: Poisons have long fascinated humans, and modern technology has allowed for controlled utilization of dangerous poisons in medicine and cosmetics, with the development of antidotes becoming crucial. Recent research focuses on reversing or preventing the toxic effects of poisons by encapsulating them in host molecules, expanding the potential for safer antidotes to be developed.

Summary: In this study, the coordination effects of protoporphyrin IX disodium salt (PpIX) with Cu-II, Fe-II, and Zn-II were investigated, along with the host-guest interactions of calixpyridinium with PpIX and the three metalloporphyrins. The bonding ratio between calixpyridinium and PpIX differed from that with the other metalloporphyrins due to the reduction of the electronegativity of PpIX caused by the coordination of metal cations. Moreover, the supramolecular nanoassemblies formed by the host-guest interactions exhibited a reversible temperature responsiveness, allowing for reversible fluorescence on-off control and potential application as an intelligent light-responsive fluorescent security ink.

Summary: Studies have been conducted on the supramolecular chemistry of iso-tellurazole N-oxides in non-polar media. However, this study introduces a derivatized iso-tellurazole N-oxide that is soluble in polar solvents and stable in aqueous media. The compound forms macrocyclic complexes with nickel (II) and iron (II) through CTe...O chalcogen bonds and kappa(6)-O bound to the metal ion, which is different from the complexes formed by soft metal ions.

Summary: A functionalized metallacage with anthracene groups was synthesized and analyzed using various techniques including UV/vis spectroscopy, NMR, ESI-TOF mass spectrometry, and X-ray single crystal diffraction. This metallacage showed specific fluorescence enhancement response to OH-, PO43-, and AcO- anions, which was attributed to the disassembly of the metallacage induced by these anions.

Summary: The naphthalene-based macrocycle prism[5]arene (NP5OCH3) acts as a novel photoinitiator with strong light absorption in the 365-405 nm range, matching LED light source for efficient initiation. The resulting linear oligomer biradicals from NP5OCH3 cleavage can be immobilized in polymers after initiating polymerization, showing lower migration rate and cytotoxicity. This cleavable macrocycle prismarene provides a new approach for designing safe and efficient photoinitiators matching long wavelength light.

Summary: This review discusses recent developments in the field of synthetic chemistry of PAH-porphyrin hybrids, focusing on phenanthrene-embedded carbaporphyrinoids and related systems. The discussion covers various aspects of phenanthriporphyrin chemistry, including its spectroscopic features, aromaticity, core reactivity, and coordination properties. The review also highlights the use of phenanthriporphyrinoids as ligands for organometallic chemistry and for constructing conformational and stereochemical switches. The potential for using related macrocycles as building blocks for carbaporphyrinoid cages is also discussed.

Summary: A highly selective route for producing levulinic acid (LA) from raw crab shells in one step has been achieved through the catalysis of the ionic liquid (IL) 1-methyl-3-(3-sulfopropyl)-imidazolium hydrogen sulfate. The relationship between the structure of ILs and the yield of LA was investigated, revealing the crucial role of both the acidity and hydrogen-bonding ability of ILs in dictating their catalytic activity. Additionally, a self-healing phenomenon driven by hydrogen-bond interactions was discovered in the chitin fraction, indicating a potential for direct depolymerization and deacetylation/depolymerization processes.

Summary: This study dynamically investigated the evolution process of humins derived from glucose, from feedstock to solid form. The key intermediates involved in humins formation were identified as etherification of dehydrated glucose and electrophilic substitution of furfuryl alcohol (FAL). Infrared spectroscopy analysis showed that specific peaks corresponded to specific structures, and the shift of peaks could be induced by oxygen or kojic acid. Structural models of glucose-derived humins at different temperatures and a successive growth diagram were proposed through various characterization techniques.

Summary: This study demonstrates a novel method for the fabrication of nitrogen-doped porous carbon (NPC) from chitosan-derived humins through in situ CO2 strategy. The formation mechanism of chitosan-derived humins by catalysis of weak acids was proposed via oligomer mechanism. The humins were transformed into porous material through the in situ release of CO2, while nonporous humins were obtained without the release of CO2 by catalysis of HOAc.

Summary: The rapid development of shell biorefining in the past decade has seen an increasing application of ionic liquids (ILs) for catalyzing the conversion of marine biomass. However, due to the greater structural complexity of marine biomass, the methodological developments of ILs in this area have been limited. This study reviews the conversion of marine biomass using acidic ILs as catalysts, comparing their characteristics with lignocellulosic biomass and showing the structural effect of marine biomass on their conversion.
