“…Nevertheless, the microreactor protocol illustrates the characteristics of the microstructured reaction system and it is the first of its kind to engineer a continuous flow process for the preparation of hyperbranched oligoglycerols. [84] Attempts to polymerize glycidol date back to the earlier work of Sandler and Berg [85] followed by several efforts to polymerize glycidol to linear products in the presence of various catalyst systems. [86] Linear PG has been obtained from the polymerization of protected glycidols and the polymerization of 3-hydroxyoxetane.…”

The application of nanotechnology in medicine and pharmaceuticals is a rapidly advancing field that is quickly gaining acceptance and recognition as an independent area of research called "nanomedicine". Urgent needs in this field, however, are biocompatible and bioactive materials for antifouling surfaces and nanoparticles for drug delivery. Therefore, extensive attention has been given to the design and development of new macromolecular structures. Among the various polymeric architectures, dendritic ("treelike") polymers have experienced an exponential development due to their highly branched, multifunctional, and well-defined structures. This Review describes the diverse syntheses and biomedical applications of dendritic polyglycerols (PGs). These polymers exhibit good chemical stability and inertness under biological conditions and are highly biocompatible. Oligoglycerols and their fatty acid esters are FDA-approved and are already being used in a variety of consumer applications, e.g., cosmetics and toiletries, food industries, cleaning and softening agents, pharmaceuticals, polymers and polymer additives, printing photographing materials, and electronics. Herein, we present the current status of dendritic PGs as functional dendritic architectures with particular focus on their application in nanomedicine, in drug, dye, and gene delivery, as well as in regenerative medicine in the form of non-fouling surfaces and matrix materials.

“…Unlike time-consuming synthesis of dendritic polyglycerols, hyperbranched polyglycerols (hbPGs) are synthesized by self-polymerization of glycidol monomers at initiating sites. To overcome the drawbacks of the wide molecular weight distribution and the uncontrollable polymerization when using base reagents in earlier studies [83], Sunder et al [84] performed the anionic ring-opening polymerization to obtain the controlled glycidol self-polymerization process, in which the slow addition strategy is adapted to attain a narrow molecular weight distribution. The reported hbPGs molecular weight is typically ranged from 1 to ~7 kDa.…”

Properties of modern semiconducting transistors and future electron or quantum devices are essentially determined by single dopant atoms. How to precisely control the individual dopant position is one of the key factors to advance these technologies. In this chapter, we first briefly introduce the research progress in single dopant devices. To fabricate single dopant devices at large scale, we then overview our previous propose to control the locations of single dopants by self-assembly of large molecules (polyglycerols) with each carrying one dopant atom. The synthesis process, doping properties, and challenges of the molecular doping technique will be thoroughly elaborated before we conclude this chapter.

Polyglycerol‐Supported Co‐ and Mn‐salen Complexes as Efficient and Recyclable Homogeneous Catalysts for the Hydrolytic Kinetic Resolution of Terminal Epoxides and Asymmetric Olefin Epoxidation

In this report we demonstrate the suitability of hyperbranched polyglycerol as high-loading support for asymmetric catalysis. A polyglycerol-supported unsymmetrical salen ligand was prepared and purified by means of ultrafiltration. The polymeric ligand was metalated with cobalt acetate to afford the corresponding supported Co-salen complex which was further utilized in the hydrolytic kinetic resolution (HKR) of terminal epoxides. Kinetic studies for HKR of 1,2-epoxyhexane using polyglycerol-supported Co-salen showed improved catalytic performance compared to the respective non-immobilized catalyst. This observation points to the presence of a positive dendrimeric effect assuming a cooper-
