Tris(4-ethynylphenyl)amine (CAS number 189178-09-4), is a tertiary amine with three 4-ethynlphenyl groups. Tris(4-ethynylphenyl)amine can undergo various reactions for synthesizing COFs, including the Sonogashira reaction and click polymerization. By reacting tris(4-ethynylphenyl)amine with tetrakis(bromophenyl)ethene using the Sonogashira reaction, an aggregation-induced emission (AIE) COF material can be produced. The resulting COF exhibits an efficiency of electrochemiluminescence of 1.72%. Tris(4-ethynylphenyl)amine can also react with ferrocene diazides for polytriazoles via azide-alkyne cycloaddition (click reaction). These hyperbranched polytriazoles act as precursors for nanostructured magnetoceramics.
Tris(4-ethynylphenyl)amine also engages in a reaction with ruthenium (Ru), resulting in the formation of a Ru-acetylide MOF. The product has multistep reversible redox behavior.
