Self-Curable Benzoxazine Functional Polybutadienes Synthesized by Click Chemistry

Synthesis of self-curable polysulfone containing pendant benzoxazine units via CuAAC click chemistry

Synthesis, characterization, and properties of new thermally curable polysulfone containing benzoxazine moieties in the side chain were investigated. First, chloromethylation and subsequent azidation processes were performed to form polysulfone containing pendant clickable azide groups. Independently, antagonist 3,4-dihydro-3-(prop-2-ynyl)-2H-benzoxazine was prepared by using paraformaldehyde, ...

Degradable dendrimers divergently synthesized via click chemistry.

Large degradable dendrimers (MW > 30 kDA) were synthesized in a divergent manner utilizing a novel 1,3,5-triazaadamantane (TAA) monomer that can degrade under acidic conditions.

Rapid Cu-Free Click Chemistry with Readily Synthesized Biarylazacyclooctynones

Bioorthogonal chemical reactions, those that do not interact or interfere with biology, have allowed for exploration of numerous biological processes that were previously difficult to study. The reaction of azides with strained alkynes, such as cyclooctynes, readily forms a triazole product without the need for a toxic catalyst. Here we describe a biarylazacyclooctynone (BARAC) that has excepti...

Functional Polymer Gels by Click- and Supramolecular Chemistry

Biological hydrogel synthesized from hyaluronic acid, gelatin and chondroitin sulfate by click chemistry.

In order to mimic the natural cartilage extracellular matrix, which is composed of core proteins and glycosaminoglycans, a biological hydrogel was synthesized from the biopolymers hyaluronic acid (HA), chondroitin sulfate (CS) and gelatin via click chemistry. HA and CS were modified with 11-azido-3,6,9-trioxaundecan-1-amine (AA) and gelatin was modified with propiolic acid (PA). The molecular s...
