N-Rich, Polyphenolic Porous Organic Polymer and Its In Vitro Anticancer Activity on Colorectal Cancer

“…Porosity and surface area analysis provided the information regarding the architectural rigidity, specific surface area, and permanent porosity of the porous organic material TrzTFPPOP. According to IUPAC nomenclature, the N 2 adsorption/desorption isotherm of TrzTFPPOP ( Figure 1 c) can be classified as a combination of two types of isotherm, where a type I isotherm is followed by a steady increase in N 2 uptake in the entire P/P 0 region [ 36 , 37 ]. At the low-pressure region, a steep increase in the N 2 uptake for the isotherms is observed, which indicates the presence of microporosity in the polymer network.…”

Urea Derivatives as Functional Molecules: Supramolecular Capsules, Supramolecular Polymers, Supramolecular Gels, Artificial Hosts, and Catalysts

“…Although it could not be introduced due to space limitations, the ureido group is also used as an important functional group in research such as polymer-based hosts, metal-organic frameworks (MOF) andc ovalento rganic frameworks (COF), as well as molecularm achines. [170][171][172][173][174] Urea is the oldest artificial organic molecule, but even today,c ompounds with interesting functions have been continuously emerging from its derivatives.…”

“…In recent years, the concept of molecular recognition has been positively applied to catalyst design, and various useful reactions catalyzed by ureido molecules have been developed. Although it could not be introduced due to space limitations, the ureido group is also used as an important functional group in research such as polymer‐based hosts, metal–organic frameworks (MOF) and covalent organic frameworks (COF), as well as molecular machines [170–174] . Urea is the oldest artificial organic molecule, but even today, compounds with interesting functions have been continuously emerging from its derivatives.…”

Using molecular straps to engineer conjugated porous polymer growth, chemical doping, and conductivity

“…p-Conjugated porous polymers (CPPs) are porous and have extended p-conjugated networks in 3 dimensions, which makes them attractive for sensing, storage, separation, and optoelectronic applications. [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15] CPPs have several interesting features that make them better suited than 1D-p-conjugated polymers for electronic and energy-related applications. [16][17][18][19][20] For example, CPPs provide a porous and morphologically stable architecture for acceptors to interact with the polymer and facilitate charge transfer.…”
