| Popis: | Synthesis of new phosphorus dendron containing 2-butyne-1,4-diol at the core is described. The divergent build-up of the dendron is based on simple condensation reactions performed by using P(O)Cl3, 3-hydroxybenzaldehyde, hydrazine hydrate, 4-hydroxybenzaldehyde and 2-mercaptoethanol. The final dendron is a Schiff’s base macromolecule possessing 8 imine bonds and 8 OH groups at the periphery. The intermediate dendrons were confirmed by IR, NMR (1H, 13C and 31P), LC–Mass and C, H, N analyzes. The structure of the final dendron 6 was confirmed by IR, NMR (1H, 13C and 31P), MALDI-TOF-MS, and C, H, N analysis. The surface morphology of the dendron 6 was understood by Scanning Electronic Microscopic study (SEM). To determine the changes in weight in relation to change in temperature of the final dendron 6 was studied by TGA/DTA analysis. |
