Polymer‐supported palladium (II) containing N2O2: An efficient and robust heterogeneous catalyst for C–C coupling reactions

“…As displayed in Figure , the spectrum of TDTB demonstrated a typical stretching band at 1643 cm −1 , which could be assigned to the –CHO stretching vibrations. The results confirmed that the structure of TDTB is consistent with the previous report . The FTIR spectrum of TbPo showed the disappearance of carbonyl stretching band at 1643 cm −1 and the generation of the stretching band at 1620 cm −1 , which was assigned to the α,β‐unsaturated ketone of the enol tautomer in the polymer moiety .…”

“…The FTIR spectrum of TbPo showed the disappearance of carbonyl stretching band at 1643 cm −1 and the generation of the stretching band at 1620 cm −1 , which was assigned to the α,β‐unsaturated ketone of the enol tautomer in the polymer moiety . The peak at 1254 cm −1 is attributed to the –C–N stretching, and the –N–H weak adsorption bands was observed at around 3421 cm −1 . The results from FTIR spectra clearly indicated that the TbPo can be obtained successfully by the condensation reaction .…”

“…These porous organic polymers are usually synthesized from one or two components via coupling or condensation reaction and obtained great attention because of their ease of synthesis, chemical and water stabilities, high specific surface areas, high thermal stability, and light weight . The catalysts (containing N 2 O 2 active center) synthesized via Schiff base reaction from the monomers of 1,3,5‐triformylphloroglucinol and amines have witnessed impressive progress for their applications in catalytic supports, electronic devices and energy storage, gas storage, anticancer agent, and water purification . In particular, several polymers (N 2 O 2 active center) were proved that they have promising performance in heterogeneous catalysis.…”

Tailoring Covalent Organic Frameworks To Capture Water Contaminants

“…Such composites can feature improved stability,d ispersibility,a nd/or materialr etention,w hile taking advantage of the properties of all materials present in the composite. In the last few years, different materials have been used as solid substrates for crystalline COF composites for adsorption in water,s uch as magnetic nanoparticles (NPs), [128][129][130][131] silica [132][133][134][135] and polystyrene beads, [136] and mixed matrix membranes (MMMs) [137] (Table 1). Recent reviewss ummarize the development of COFs as solid sorbents for sample preparation and as chromatographic stationary phases, [6,138] as well as the advances on COF thin films.…”

Wasser‐Hochflussmembranen auf Basis der kovalenten organischen Gerüststruktur COF‐LZU1 für die Farbstoffabtrennung durch Nanofiltration

“…Bekannt sind einige Versuche,s ogenannte Mixed-Matrix-Membranen (MMMs) auf Basis von COF-Partikeln in geeigneten Polymeren zu entwickeln. [9] Nur wenige Arbeiten sind bekannt zur Präparation von COF-Membranschichten auf porçsen Tr ägern. [10] Banerjee et al berichten über die Entwicklung einer selbsttragenden COF-Membran fürd ie NF von organischen Lçsungsmitteln, [11a] aber diese Membran ohne Tr äger musste mehrere hundert Mikrometer dick sein, um ausreichende mechanische Stabilitätzubesitzen.…”
