The article was titled 《An Accelerated Modular-Orthogonal Ni-Catalyzed Methodology to Symmetric and Nonsymmetric Constitutional Isomeric AB2 to AB9 Dendrons Exhibiting Unprecedented Self-Organizing Principles》.Application of 2675-79-8 The article contains the following contents:
Three libraries consisting of 30 sym. and nonsym. constitutional isomeric phenolic acids with unprecedented sequenced patterns, including two AB2, three AB3, eight AB4, five AB5, six AB6, three AB7, two AB8, and one AB9 synthesized by accelerated modular-orthogonal Ni-catalyzed borylation and cross-coupling were reported. A single etherification step with 4-(n-dodecyloxy)benzyl chloride transformed all these phenolic acids, of interest also for other applications, into self-assembling dendrons. Despite this synthetic simplicity, they led to a diversity of unprecedented self-organizing principles: lamellar structures of interest for biol. membrane mimics, helical columnar assemblies from rigid-solid angle dendrons forming Tobacco Mosaic Virus-like assemblies, columnar organizations from adaptable-solid angle dendrons forming disordered micellar-like nonhelical columns, columns from supramol. spheres, five body-centered cubic phases displaying supramol. orientational memory, rarely encountered in previous libraries forming predominantly Frank-Kasper phases, and two Frank-Kasper phases. Lessons from these self-organizing principles, discovered within a single generation of self-assembling dendrons, might help elaborate design principles for complex helical and nonhelical organizations of synthetic and biol. matter. In the part of experimental materials, we found many familiar compounds, such as 1-Bromo-3,4,5-trimethoxybenzene(cas: 2675-79-8Application of 2675-79-8)
1-Bromo-3,4,5-trimethoxybenzene(cas: 2675-79-8) is an important raw material and intermediate used in organic synthesis, pharmaceuticals, agrochemicals and dyestuff.Application of 2675-79-81-Bromo-3,4,5-trimethoxybenzene can be used to synthesize N,N′-diarylated indolo[3,2-b]carbazole derivatives, which can find applications in electrophotography.
