Ossila 5'-(4,4,5,5-Tetramethyl-1,3,2-dioxaborolan-2-yl)-[1,1':3',1''-terphenyl]-4,4''-diamine B3661

This compound, 5'-(4,4,5,5-Tetramethyl-1,3,2-dioxaborolan-2-yl)-[1,1':3',1''-terphenyl]-4,4''-diamine (CAS 2754262-59-2), is a meta-terphenyl building block for covalent organic frameworks (COFs) and for semiconducting molecules aimed at OLEDs and electroluminescent devices. It is supplied as an off-white powder with >98% purity.

Its central meta-terphenyl unit carries one pinacolborane (Bpin) group and two amine groups. The Bpin group takes part in Suzuki coupling with aryl halides, and the amines serve as nucleophiles in substitution chemistry. Because the two functionalities can be addressed one after the other, a COF network can be built first and then modified afterwards.

Macromolecules assembled from this ligand are highly conjugated and semiconducting. The bent, non-linear geometry of the core also makes it useful for preparing macrocycles whose cavity size can be tailored to host guest species.

• Synthesis of cross-linked, semiconducting covalent organic frameworks using its amine and Bpin groups.
• Post-functionalization of COF networks through stepwise reactions.
• Preparation of semiconducting molecules for OLEDs.
• Development of materials for electroluminescent cells.
• Construction of macrocycles with tailored cavities for host-guest interactions.

• Product code: B3661
• M​olecular Weight: 386.29 g/mol
• Classification / Family: COFs, Pinacolborane ligands, Amine ligands, Semiconducting molecules, Electroluminescence, OLEDs
