The Role of Silicon in Dendritic Polymer Chemistry,interest in polymer science . This can be easily seen from the impressive growth in the number of publications on these unique polymers, which soared from less than a dozen in the 1970s, to over 10,000 (in scientific journals and patent literature) by the end of 2007 . At present, new publicatAcupressure 发表于 2025-3-22 07:54:33

Carbosilane Dendrimers,olylysine dendrimers and the seminal research by Tomalia and Newkome in the mid-1980s established that such molecules could indeed be prepared . Tomalia et al. used trifunctional nitrogen branch points and Newkome chose tetrafunctional carbon branch points. These dendrimers contained etherFantasy 发表于 2025-3-22 13:15:09
Polysilane Dendrimers,ars because of their electronic, optical, structural, and chemical properties . In particular, the σ-conjugation of the –Si–Si– backbone has attracted much attention compared with analogous carbon polymer systems. Although, in contrast to the numerous reports on polysilanes with linear main chain轿车 发表于 2025-3-22 19:41:47
Polycarbosilazane and Related Dendrimers and Hyperbranched Polymers, 2]. These polymers are characterized by having either a –Si–N– backbone (polysilazanes) or a –R–Si–N– backbone (polycarbosilazanes). On the other hand, dendritic analogs are relatively rare. Polysilazane dendrimers are essentially nonexistent, and the syntheses of polycarbosilazane dendrimers have不法行为 发表于 2025-3-22 21:19:21
