Thermodynamic investigation of G2 and G4 siloxane dendrimers with trimethylsilyl terminal groups

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

“…The standard thermodynamic characteristics of the glass transition and glassy state of the studied hybrid dendrimer G1{Si} 13 [Ar] 32 are presented in Table 2 in comparison to the data for the investigated organosilicon [ 35 , 40 , 41 , 42 ] and pyridylphenylene [ 45 , 46 ] dendrimers of the first generation. Molecular structures of the calorimetrically studied G1 dendrimers are shown in Figure 5 .…”

“…The arrangement of the dendritic blocks in a different manner (i.e., a flexible core and a rigid shell or vice versa) allows for a controllable synthesis of principally new dendrimers with the desired characteristics [ 35 ]. The results of our calorimetric investigations of the widespread families such as carbosilane [ 36 , 37 , 38 ], siloxane [ 39 , 40 , 41 ], and polyphenylene [ 42 , 43 ] dendrimers with different molecular structure of the inner sphere and the surface functional groups were published earlier.…”

Adsorption of Silicon-Containing Dendrimers: Effects of Chemical Composition, Structure, and Generation Number

“…In the past few years, an interest in the study of these dendrimers in bulk has been increasing [ 26 , 27 , 28 , 29 , 30 , 31 , 32 , 33 , 34 , 35 , 36 , 37 , 38 ]. Research was carried out both by experimental methods and by computer simulations.…”

“…Thus, a more detailed study of carbosilane dendrimers near the adsorbing surface, which would take into account the atomic structure of these macromolecules, is important for a better understanding of the general influence of the generation number on their conformational behavior. Dendrimers of the siloxane families, synthesized about 30 years ago [ 37 , 38 ], have just begun to be studied [ 29 , 30 ], and their modeling is very interesting and has a predictive value. Furthermore, recently, some works appeared on the synthesis and study of physical properties of hybrid dendrimers consisting of segments of various chemical natures [ 39 , 40 ], which have strong potential for the creation of membrane materials.…”
