Two novel hybrid porous polymers were easily prepared by the Friedel-Crafts reaction of octavinylsilsesquioxane with triphenylphosphine and triphenylphosphine oxide, respectively. They possessed unique bimodal pores with uniform micropores and mesopores centered at 1.5 nm and 3.7 nm, respectively, high surface areas up to 1105 m 2 g À1 , high thermal stability and an excellent sizeselective adsorption for dyes. These hybrid porous polymers are very promising in dye separation, water purification and treatment.

“…Monte Carlo simulations were performed to search possible molecular packing for the RDX/solvent cocrystals in eight space group ( C2/c, P‐1, P2 1 , P2 1 /c, P2 1 2 1 2 1 , Pbca, Pbcn , and Pna2 1 ), which cover over 85% of organic molecular solids and are enough to find most stable polymorphs for the organic compounds . During the simulations, empirical Dreiding force field (FF) was adopted to minimize and relax the molecular structure and crystal lattice.…”

“…Recently, Liu et al. predicted a series of 1:1 supramolecular synthons of both α‐ and β‐HMX conformers based on dipole–dipole interactions . However, dipole moment cannot reveal the local structure and property of the molecules that play a very important role in the intermolecular interactions.…”

Cocrystallization has attracted growing interests in the energetic field as it can tune properties by selecting and arranging existing molecules. Herein, the application of molecular electrostatic potential surface to predict supramolecular synthons for 1,3,5‐trinitro‐1,3,5‐triazinane (RDX)/solvent cocrystals is demonstrated. Six RDX/solvent supramolecular synthons are constructed and investigated by density functional theory. The results of Bader's atoms in molecules (AIM) and independent gradient model (IGM) indicate that unconventional CH···O type hydrogen bonds are the main intermolecular interactions between RDX and solvents. The thermodynamic properties are studied to assess the spontaneity of assembly reactions. The most stable packings for the supramolecular synthons of the RDX/solvents are predicted and they present lower sensitivity than RDX. The work may provide valuable insight for the rational design of RDX‐based cocrystals and promote the application of supramolecular chemistry in the field of explosives.

A series of hybrid nanoporous polystyrenes were synthesized from commercial polystyrene (PS) and cubic octavinylsilsesquioxane (OVS) via the Friedel-Crafts reaction. The porosity of the resulting hybrid polymers could be fine-tuned by varying the ratio of PS and OVS. The resulting polymers, HCP-1 to HCP-9 had apparent Brunauer-Emmett-Teller surface areas (S BET ) in a range of 2.6 to 767 m 2 g À1 , with total pore volumes in the range of 0.36 to 0.90 cm 3 g À1 . The S BET was maximum when OVS loading was 9.1 wt%; it then decreased to almost no porosity before increasing again with the increase of OVS loading. The thermal decomposition temperatures of the hybrid polymers were close to pure PS under a N 2 atmosphere, but the residues increased with the increase of OVS loading. The gas sorption applications revealed that HCP-3 possessed H 2 uptake of 3.01 mmol g À1 (0.60 wt%) at 77 K and 1.01 bar and CO 2 uptake of 1.12 mmol g À1 (4.93 wt%) at 298 K and 1.01 bar. † We dedicate this paper to Prof. Hongzhi Liu's mother, who is dearly missed by all members of the family.‡ Electronic supplementary information (ESI) available: The elemental analysis results of HCP-1 to HCP-9; FT-IR spectra of HCP-1, HCP-2, HCP-5 to HCP-7; FE-SEM images of HCP-3 to HCP-9 with different magnications and areas.
