Porous inorganic–organic hybrid polymers derived from cyclic siloxane building blocks: Effects of substituting groups on mesoporous structures

Diphenylphosphine-Substituted Ferrocene/Silsesquioxane-Based Hybrid Porous Polymers as Highly Efficient Adsorbents for Water Treatment

“…As a result, there have been extensive studies to develop new and efficient methods to remove these toxins from water. Covalently linked porous hybrid polymers − with large specific surface area, low density, and high thermal and chemical stabilities have shown a great deal of promise as efficient and recyclable adsorbents for various dyes and metal ions. ,− Multifunctional and rigid cage silsesquioxanes with three-dimensional nanosized organic–inorganic structures represent interesting building blocks for the construction of hybrid porous polymers. − A number of functional silsesquioxane-based porous hybrid polymers are developed using different synthetic methods, which include the Friedel–Crafts reaction, Heck reaction, , Scholl coupling, Sonogashira cross-coupling, cationic polymerization, radical polymerization, and hydrosilation . There remains considerable space to explore new types and applications of silsesquioxane-based hybrid porous polymers.…”

An eight‐membered cyclosiloxane conjugated microporous polymer performed a rapid and sensitive fluorescence detection of 2,4‐dinitrophenol

“…TGA is to place the polymer in a nitrogen environment, and the temperature rises from 25°C to 800°C, in which the thermal stability is analyzed by observing the weight loss of the polymer in this process (Figure 2). We can see from Figure 2 that TMPS has good thermal stability and weight loss starts at 510°C, probably due to the decomposition of the organic components in the polymer and consumption at high temperatures 20,32 . The results of TGA suggest that TMPS is also well applied at higher temperature.…”

“…Traditional porous materials such as activated carbon and zeolite, despite their high strength and excellent thermal stability, have unlimited subsequent functionalization capabilities, thus requiring porous organic materials to accommodate better applications to develop 19 . Porous organic materials have attracted much attention due to their advantages of diverse functions, easy synthesis methods and easy to modify the structure 20 . However, most of the porous organic materials lack excellent mechanical strength and high hydrothermal stability 19 .…”

“…The conjugate macrocyclic polymer material prepared by Yang's research group can be used as a fluorescent sensor for metal ions and organic molecules 24 . Eight‐membered cyclosiloxane belongs to the middle ring molecule, Sozzani and Okubo prepared eight‐membered cyclosiloxane supercrosslinked polymers which were used to adsorb gas 20,23 . The preparation and application of the eight‐membered cyclosiloxane‐based CMPs have not been reported.…”

“…The preparation and application of the eight‐membered cyclosiloxane‐based CMPs have not been reported. Cyclosiloxane is used as building blocks of PHPs that was compounded by Friedel–Crafts arylation 20 . Friedel–Crafts arylation has become an important method to assemble molecules and prepare polymers due to its characteristics of cheap catalyst, mild reaction conditions and high reaction efficiency 23 …”
