Special Issue Information

Dear Colleagues,

Porous polymers are materials with rich microstructures and have wide application prospects in the fields of catalysis, adsorption, separation, drug delivery and release, and sensing due to their unique pore structure, different skeleton charge characteristics, and adjustable surface hydrophobicity. Porous polymers have the following advantages: 1) open pore structure; 2) good physical and chemical stability; 3) diversity of organic blocks; and 4) different structures and functions can be obtained by means of functional group modification or synthesis condition control. However, it is a major challenge for chemists and material scientists to design and control the size, shape, spatial uniformity, and atomic and molecular composition of nano or functional porous materials.

This Special Issue aims to cover recent progress and trends in the design, synthesis, and applications of porous materials in the new field. Submissions are welcome but not limited to the topics listed below. Types of contributions to this Special Issue can be full research articles, short communications, and reviews focusing on porous polymers.

Potential topics include but are not limited to:

  • Porous structure design;
  • Characterization and improvement of pore structure integrity;
  • Novel preparation techniques;
  • Characterization of morphology and structure;
  • Catalysis;
  • Mechanical properties;
  • Thermal analysis;
  • Mass transport characterization;
  • Application of the porous materials in new fields.

Nitrogen-rich porous organic polymers were fabricated through a nonreversible ring-opening reaction from polyamines and polyepoxides (PAEs). The epoxide groups reacted with both primary and secondary amines provided by the polyamines at different epoxide/amine ratios with polyethylene glycol as the solvent to form the porous materials. Fourier-transform infrared spectroscopy confirmed the occurrence of ring opening between the polyamines and polyepoxides. The porous structure of the materials was confirmed through N2 adsorption–desorption data and scanning electron microscopy images. The polymers were found to possess both crystalline and noncrystalline structures, as evidenced by X-ray diffraction and high-resolution transmission electron microscopy (HR-TEM) results. The HR-TEM images revealed a thin, sheet-like layered structure with ordered orientations, and the lattice fringe spacing measured from these images was consistent with the interlayer of the PAEs. Additionally, the selected area electron diffraction pattern indicated that the PAEs contained a hexagonal crystal structure. The Pd catalyst was fabricated in situ onto the PAEs support by the NaBH₄ reduction of the Au precursor, and the size of the nano-Pd was about 6.9 nm. The high nitrogen content of the polymer backbone combined with Pd noble nanometals resulted in excellent catalytic performance in the reduction of 4-nitrophenol to 4-aminophenol. Full article
