New discoveries in chemical research and development in 2021. The dynamic chemical diversity of the numerous elements, ions and molecules that constitute the basis of life provides wide challenges and opportunities for research. In an article, author is Suarez-Suarez, Silvia, once mentioned the application of 615-37-2, Name is 1-Iodo-2-methylbenzene, molecular formula is C7H7I, molecular weight is 218.035, MDL number is MFCD00001042, category is thiomorpholine. Now introduce a scientific discovery about this category, Electric Literature of 615-37-2.
We describe a new and very versatile method to place chosen chemical functionalities at the edge of the pores of macroporous materials. The method is based on the synthesis and self-assembly of inorganic block copolymers (BCPs) having chiral rigid segments bearing controllable quantities of randomly distributed functional groups. The synthesis of a series of optically active block copolyphosphazenes (PP) with the general formula [NP(R-O2C20H12)(0.9)(FG)(0.2)](n)-b-[NPMePh](m) (FG=-OC5H4N (6), -NC4H8S (7), and -NC4H8O (8)), was accomplished by the sequential living cationic polycondensation of N-silylphosphoranimines, using the mono-end-capped initiator [Ph3PNPCl3][Cl] (3). The self-assembly of the phosphazene BCPs 6-8 led to chiral porous films. The functionality present on those polymers affected their self-assembly behaviour resulting in the formation of pores of different diameters (D-n=111 (6), 53 (7) and 77nm (8)). The specific functionalisation of the pores was proven by decorating the films with gold nanoparticles (AuNPs). Thus, the BCPs 6 and 7, having pyridine and thiomorpholine groups, respectively, were treated with HAuCl4, followed by reduction with NaBH4, yielding a new type of block copolyphosphazenes, which self-assembled into chiral porous films specifically decorated with AuNPs at the edge of the pores.
