Porous organic polymers: Structure, surface chemistry and adsorption of certain gases

Characterization of Melamine−Formaldehyde Resins by XPS, SAXS, and Sorption Techniques

“…During the past three decades, the synthesis and characterization of organic polymers have become one of the most important research areas in polymer science. 1,2 The study of polymer surface and geometrical structure is of analytical relevance. Many industrial and analytical applications of polymers require systems with specific surface properties.…”

Adsorption and chromatographic properties of some polymeric and ionic adsorbents

“…With the aid of gas chromatography we determined the heats of adsorption of nitrogen-containing heterocyclic compounds on BaS04 and calculated the contributions of the dipole-ion specific interaction Aqa to the total adsorption energy (Figure 6). 17 As is seen, the presence of a nitrogen atom with an unshared electron pair in the benzene ring increases greatly Aqa of the adsorbed nitro- (9) 2-picoline; (10) 3-picoline; (11) 4-picoline; (12) 2,6-lutidine; (13) 2,5-lutidine; (14) 3,5-lutidine;…”

“…Figure6. Initial adsorption heats of BaS04 vs. the number of carbon and nitrogen atoms in the molecules: (1) re-hydrocarbons;(2) benzene; (3) toluene; (4) ethylbenzene; (5) p-xylene; (6) mxylene; (7) o-xylene; (8) pyridine;(9) 2-picoline;(10) 3-picoline; …”

Multifunctional carbon nanotubes covalently coated with imine-based covalent organic frameworks: exploring structure–property relationships through nanomechanics

“…They form covalently bonded organic frameworks with well controlled 2D o 3D structures as a consequence of the assembling of molecular building blocks. [6][7][8][9] The molecular units are organic molecules that react and form strong covalent bonds, which provide rigidity to form novel architectures. Design and development of POP-based hybrid structures holds interesting prospects to create hybrid materials with unprecedented properties.…”
