“…NH1420 is a sterically hindered amine of aspartic acid ester derivatives, which has been widely used in the construction of polyurea materials. [ 32,33 ] Due to the site‐blocking effect of numerous ester groups, NH1420 reacts with isocyanates at a much lower rate as compared with the reaction between common amine and imine groups, which gels in 10–20 min and is cured after 3 h at the room temperature without catalyst. [ 34 ] Therefore, cross‐linked networks with high cross‐linking density can be obtained by simple mixing and curing of NH1420 with polyisocyanates, such as THDI.…”

Inspired by mechanically interlocking supramolecular materials, exploiting the size difference between the bulky solvent and the cross‐linked network mesh, a molecular clogging (MC) effect has been developed to effectively inhibit solvent migration in organogels. A bulky solvent (branched citrate ester, BCE) with a molecular size above 1.4 nm is designed and synthesized. Series of MC‐Gels are prepared by in situ polymerization of crosslinked polyurea with BCE as the gel solvent. The MC‐Gels are colorless, transparent and highly homogeneous, show significantly improved stability than gels prepared with small molecule solvents. As solvent migration is strongly inhibited by molecular clogging, the solvent content of the gels can be precisely controlled, resulting in a series of MC‐Gels with continuously adjustable mechanics. In particular, the modulus of MC‐Gel can be regulated from 1.3 GPa to 30 kPa, with a variation of 43,000 times. The molecular clogging effect also provides MC‐Gels with unique high damping (maximum damping factor of 1.9), impact resistant mechanics (high impact toughness up to 40.68 MJ m−3). By applying shatter protection to items including eggs and ceramic armor plates, the potential of MC‐Gels as high strength, high damping soft materials for a wide range of applications has been well demonstrated.This article is protected by copyright.

Theoretical studies of the bonding interactions and most important properties are carried out for isolable phosphanylphosphinidene complexes of transition metals. Three main types of phosphanylphosphinidene complexes are distinguished, based on the way in which the phosphanylphosphinidene ligand bonds to the metal center: (i) side-on complexes of platinum, where the R 2 P -P α ligand mimics structural features of free singlet phosphanylphosphinidenes with short, polarized, double P-P bonds and two lone electron pairs on the terminal P atom. In this case, interactions between the platinum center and the phosphanylphosphinidene ligand are determined by π(PP)→s(Pt) donation and d(Pt)→π*(PP) back-dona- [a]
