Core/shell hybrid dendrimers: Controllable rigidity determines molecular behaviour

Thermodynamic Properties of the First-Generation Hybrid Dendrimer with “Carbosilane Core/Phenylene Shell” Structure

“…The sample of the hybrid dendrimer G1{Si} 13 [Ar] 32 was synthesized at the Nesmeyanov Institute of Organoelement Compounds of Russian Academy of Sciences (Moscow) via the Diels–Alder cycloaddition reaction according to the procedure described in detail elsewhere [ 44 ]. The synthesized compound was a light-brown powder under the standard conditions and characterized by monodispersity on the generation number.…”

“…The structure and the composition of dendrimer G1{Si} 13 [Ar] 32 were confirmed by elemental analysis, 1 H-, 13 C-, and 29 Si-NMR spectroscopy (Bruker AVANCE III HD spectrometer; 500.13 MHz for 1 H; 125.76 MHz for 13 C; CDCl 3 was used as a solvent), and MALDI-TOF mass spectrometry (Bruker BIFLEX III spectrometer; a 337 nm nitrogen laser; indole-3-acrylic acid was used as a matrix, and silver trifluoroacetate was used as a cationization agent).

Synthetic Methodologies for Chelating Polymer Ligands: Recent Advances and Future Development

“…For example, photosensitive hybrid dendrimers G1‐G3 was obtained by the addition of amidoamine dendrons to the alternating St‐maleic anhydride copolymer . It should be also noted hybrid dendrimers consisting of flexible carbosilane interior and rigid aromatic shell developed by Diels‐Alder cycloaddition of previously obtained carbosilane dendrimers and aromatic cyclopentadienones . Various structural classes of dendritic copolymers, such as linear‐dendritic block copolymers, a dendrimer‐like star‐branched block copolymer, multiarm dendritic initiators, dendritic focal point chain transfer agents, etc., are of interest .…”
