WebAs a typical example carbosilane dendrimers up to the third generation containing a N,N′,N″-1,3,5-benzenetricarboxamide core (G1–G3) have been synthesized. This new class of molecules has been studied as host molecules and they have been found to bind protected amino acids as guest molecules via hydrogen bonding interactions. WebNo direct Si Si bond is present in 1 in spite of the short interatomic distance; however, the long C C distance does not prevent weak bond formation in 2.These results are predicted by an analysis of the compounds with the electron localization function. The explanation … Web6 de jan. de 2024 · We previously demonstrated that the addition of phenyl-CN lateral units in the central linker of dimeric G-3 dendrimers not only effectively broadened the range of columnar phase but also lowered the temperature of solidification on cooling [], which can be important on the point of view of further practical applications.Discotic columnar (DC) … howard ungerleider dow chemical company
