Arylformylacetonitriles are versatile and attractive synthons in organic synthesis owing to their high reactivity. Among the numerous transformations involving arylformylacetonitriles, multicomponent reactions (MCRs) offer straightforward and effective routes to assemble the reactants into a wide range of five-and six-membered heterocyclic systems including pyrrole, pyrazole, triazole, furan, pyridine, pyrimidine, and pyran. This review collects the recent advances and applications of arylformylacetonitriles in MCRs for the synthesis of monocyclic or polycyclic heterocycles published in the literature since 2001.

As a representative class of sustainable polymer materials, biodegradable polymers have attracted increasing interest in recent years. Despite significant advance of related polymerization techniques, realizing high sequence‐control and easy‐handling in ring‐opening (co)polymerizations still remains a central challenge. To this end, a promising solution is the development of valence‐variable metal‐based catalysts for redox‐induced switchable polymerization of cyclic esters, cyclic ethers, epoxides, and CO2. Through a valence‐determined electron effect, the switch between different catalytically active states as well as dormant state contributes to convenient formation of polymer products with desired microstructures and various practical performances. This redox‐controlled switchable strategy for controlled synthesis of polymers is overviewed in this Review with a focus on potential applications and challenges for further studies.

The impact of hydrogen bond formation on the supramolecular assembly of two perylene imide derivatives (PMAMI and PDINH) was systematically investigated in solution and at the liquid-solid interface. PDINH has intrinsic hydrogen bond sites, but this is not the case for PMAMI. The solution assembly was explored by morphological methods (SEM, AFM, TEM and cryo-TEM) and spectral characterization (UV-vis, FL, XRD, and FTIR spectra). The surface assembly at the liquid-solid interface was detected by scanning tunneling microscopy (STM). It was found that in a mixed solution (THF/MeOH, 10 v%/90 v%), PMAMI formed nanofibers together with large sheet structures and PDINH assembled into uniform nanosheets, suggesting different molecular packing routes. The assembled structures could be adjusted by varying the solvent polarity for both molecules. At the liquid-solid interface, clearly distinguished surface nanostructures from PMAMI and PDINH were easily observed. Based on all spectral and morphological characterizations, it was suggested that in solution the assembly of PMAMI was mainly derived by π-π stacking interactions; on the other hand, the synergetic interaction of hydrogen bonds and π-π stacking was the reason for the hierarchical assembly of PDINH. Hydrogen bonds could be formed both for PMAMI and PDINH and stabilized nanostructures at the liquid-solid interface. This investigation could be useful in designing perylene imide-based building blocks for fabricating supramolecular assemblies with predetermined nanostructures and properties.
