چکیده
Unprecedented tetracyclic polymer topologies with spiro- and a bridged-type quatrefoil forms are effectively constructed through an alkyne-azide, click-linking reaction by employing a kyklo-telechelic poly(tetrahydrofuran), poly(THF), precursor having an azide group, obtained through an electrostatic self-assembly and covalent fixation (ESA-CF) process, and complementary tetrafunctional alkyne reagents of either a pentaerythritol derivative or a four-armed star telechelic polymer precursor.

Effective click construction of bridged- and spiro-multicyclic polymer topologies with tailored cyclic prepolymers (kyklo-telechelics).
An alkyne-azide addition, i.e., click, reaction in conjunction with an electrostatic self-assembly and covalent fixation (ESA-CF) process has been demonstrated to effectively construct a variety of unprecedented multicyclic polymer topologies. A series of single cyclic poly(tetrahydrofuran), poly(THF), precursors having an alkyne group (Ia), an azide group (Ib), two alkyne groups at the opposit...

A concise two-step click/ESA-CF process has been developed to prepare a kyklo-telechelic poly(tetrahydrofuran), poly(THF), having three functional groups at the constant intervals. Thus, a key linear precursor (I), having N-phenylpyrrolidinium salt groups at the chain ends and having two hydroxyl groups at the prescribed inner positions, has been prepared through the alkyne−azide addition (clic...

Polyvinyltetrazole (PVT) is produced from acrylonitrile (AN) monomer by using free-radicalpolymerization and Click Chemistry methods. The resulting polymer with a broad range of tetrazolegroup contents was conveniently synthesized through [3+ 2] azide-nitrile cycloaddition reaction ofnitrile-containing polymer with sodium azide in DMF. The prepared PVT was characterized by13CN...
متن کاملCu(I)-assisted click chemistry strategy for conjugation of non-protected cross-bridged macrocyclic chelators to tumour-targeting peptides.
Copper(I)-catalyzed azide-alkyne cycloaddition (CuAAC) click chemistry has inherent challenges for copper-labeled radiopharmaceuticals. An azide-modified phosphonate-based cross-bridged macrocyclic chelator was synthesized for click chemistry conjugation with azide-modified Y3-TATE (a somatostatin analogue) on resin, without the need for protecting the chelator. The (64)Cu-labeled bioconjugate ...

(57) ABSTRACT Micro-cavity resonant sensors have outer surfaces that are functionalized using click chemistry, e.g., involving a cycloaddition reaction of an alkyne functional group and an azide functional group. A first polymer linking element binds to an outer surface of the micro-cavity and has an azide functional group, which bonds to an alkyne functional group of a second polymer linking e...
