9-(4-Ethynylphenyl)carbazole (CAS 262861-81-4) is a carbazole building block carrying an ethynylphenyl substituent. Supplied by Ossila as a yellow powder with a purity above 97%, it serves as a ligand for cross-linked covalent organic framework (COF) and metal-organic framework (MOF) networks and as a precursor for photoluminescent and supercapacitor macromolecules.
The terminal alkyne makes the compound highly reactive, allowing it to take part in Sonogashira coupling and click chemistry to build semiconducting macromolecules. It can also be oxidized with FeCl3 to give oligomers.
Reported uses include carbazole-functionalized corannulene-viologen ambipolar polymers for electrochromic supercapacitors, which show high optical contrast and a specific capacitance of 394 F/g. When linked to naphthalene and perylene diimides, it forms D-π-A-π-D n-type semiconductors with electron mobility of up to 0.3 cm2/V·s.
