A fast double-stage convergent synthesis of dendritic polyethers
L'abbe, Gerrit,Forier, Bart,Dehaen, Wim
, p. 2143 - 2144 (1996)
Two tert-butyldiphenylsilyl-protected synthons 7 and 9 are prepared in excellent yields and used in a one-pot synthesis of higher generation polyether dendrons.
Synthesis of dendritic phenol ether derivatives with a naphthalene core
Xiang, Zhonghua,Cao, Derong
, p. 1318 - 1324 (2008/09/19)
A series of dendritic phenol ether derivatives with a naphthalene core were synthesized by the Williamson reaction as a coupling reaction between 1-hydroxymethylnaphthalene and polyether-based dendritic fragments in the presence of phase-transfer catalyst and alkali. The modified method for chlorination of dendritic benzyl alcohol was also developed using PPh3 and CCl4 as reagents and CH2Cl2/CCl4 as solvent. Copyright Taylor & Francis Group, LLC.
Optical switching and antenna effect of dendrimers with an anthracene core
Cao, Derong,Dobis, Silvia,Gao, Chunmei,Hillmann, Sabine,Meier, Herbert
, p. 9317 - 9323 (2008/12/20)
Dendrimers 6Gi (i=1-4) consisting of an anthracene core and Frechet dendrons which are attached via a CH2OCH2 chain in the 9-position undergo quantitative and completely reversible intramolecular [4π+4π] cycloaddition. The
Facile synthesis of aryl ether dendrimer from unprotected AB2 building blocks using thionyl chloride as an activating agent
Yamazaki, Natsuko,Washio, Isao,Shibasaki, Yuji,Ueda, Mitsuru
, p. 2321 - 2324 (2007/10/03)
A novel, rapid, inexpensive, and highly efficient convergent approach for the synthesis of a Frechet- type aryl ether dendrimer using thionyl chloride has been developed. In this method, the purification of each dendron and a dendrimer occurs by recrystallization, extraction, and precipitation. The MALDI-TOF MS spectrum supported the formation of the G2, G3, and G4 dendrons and the star-shaped G4 dendrimer.
Photoisomerization of stilbene dendrimers: The need for a volume-conserving isomerization mechanism
Uda, Mayuko,Mizutani, Takuo,Hayakawa, Junpei,Momotake, Atsuya,Ikegami, Masashi,Nagahata, Ritsuko,Arai, Tatsuo
, p. 596 - 605 (2007/10/03)
Highly branched stilbene dendrimers were synthesized and their photochemical behavior was studied. Even the stilbene dendrimer with molecular weight over 6500 underwent transcis isomerization in the excited singlet state within the lifetime of 10 ns. The
Alternative convergent and accelerated double-stage convergent approaches towards functionalized dendritic polyethers
Forier,Dehaen
, p. 9829 - 9846 (2007/10/03)
Alternative convergent synthesis strategies for the preparation of dendritic macromolecules, using either mesylate activation or the Mitsunobu reaction, are described. The synthesis can be further accelerated by using a double stage convergent approach. T
Preparation of polymers with controlled molecular architecture. A new convergent approach to dendritic macromolecules
Hawker, Craig J.,Fréchet
, p. 7638 - 7647 (2007/10/02)
The novel convergent growth approach to topological macromolecules based on dendritic fragments is described. The polyether dendritic fragments are prepared by starting from what will become the periphery of the molecule and progressing inward. In the fir
