Regulating the coordination capacity of ATMP using melamine: facile synthesis of cobalt phosphides as bifunctional electrocatalysts for the ORR and HER

“…29 All the evidence reveals the fact that there are hydrogen bond and ionic interactions between L1 and L2. 26,30 The Raman spectrum is illustrated in Fig. 1B, where the intensity of the stretching vibrations of P-C (720 cm −1 ), P-OH (978 cm −1 ) and PvO (1025 cm −1 ) in the L1 curve is greatly reduced.…”

Direct Metal-Free Synthesis of Uracil- and Pentaazaphenalene-Functionalized Porous Organic Polymers via Quadruple Mannich Cyclization and Their Nucleobase Recognition Activities

“…32−39 Walter et al, for example, documented the synthesis of adenine-and thymine-functionalized porous polymers through Stille cross-coupling of 2,6bis(trimethylstannyl) benzo[1,2-b:5,4-b′]dithiophene with 2,5dibromo-3-(6-adenine)hexylthiophene and 2,5-dibromo-3-(6thymine)hexylthiophene, respectively, in the presence of Pd catalyst Pd(PPh 3 ) 4 in the environmentally unfriendly solvent DMF at 100 °C for 12 h. 15 In addition, uracil-functionalized poly(3-hexylthiophene) as a hole-injecting/transporting layer in an organic light-emitting device is synthesized through the click reaction between poly(3-hexyl azide thiophene) and propargyl uracil in DMF/THF cosolvent in the presence of pentamethyldiethylenetriamine and copper bromide as catalysts. 32 Shang et al reported the synthesis of uracil-functionalized porous organic polymer through the hydrothermal polycondensation between melamine and uracil in an environmentally unfriendly solvent (DMSO) and under a high temperature of 180 °C for 12 h. 39 Despite the rapid rise in the synthesis and use of architecturally incorporated nucleobase-functionalized POPs, there are certain unavoidable challenges in the production of most POPs. First, noble metal catalysts such as palladium are required in a diverse variety of synthesis processes, posing a cost barrier to future commercial production.…”

“…Nucleobase-functionalized porous organic polymers are often prepared through a variety of techniques, including condensation, cyclization, metal-mediated coupling/addition, and solvothermal processes. − Walter et al, for example, documented the synthesis of adenine- and thymine-functionalized porous polymers through Stille cross-coupling of 2,6-bis­(trimethylstannyl) benzo­[1,2-b:5,4-b′]­dithiophene with 2,5-dibromo-3-(6-adenine)­hexylthiophene and 2,5-dibromo-3-(6-thymine)­hexylthiophene, respectively, in the presence of Pd catalyst Pd­(PPh 3 ) 4 in the environmentally unfriendly solvent DMF at 100 °C for 12 h .

Effects of Fatty Alcohols with Different Chain Lengths on the Performance of Low pH Biomass-Based Foams for Radioactive Decontamination

“…However, little research has been conducted on the effect of fatty alcohols with different chain lengths on low pH foam performance. Phytic acid extracted from plants [ 20 ] has a strong chelating effect on radioactive metal ions at low pH [ 21 , 22 ], which can improve the dissolution efficiency of radioactive contaminants on a surface. It is very suitable for use as a pH conditioning agent.…”
