5'-(4,4,5,5-Tetramethyl-1,3,2-dioxaborolan-2-yl)-[1,1':3',1''-terphenyl]-4,4''-diamine (CAS number 2754262-59-2) possesses a meta-terphenyl core, bearing with a pinacolborane and two amine groups. The pinacolborane group undergoes Suzuki coupling reactions with aryl halides, while the amine groups act as nucleophiles for nucleophilic substitution reactions. 5'-(4,4,5,5-Tetramethyl-1,3,2-dioxaborolan-2-yl)-[1,1':3',1''-terphenyl]-4,4''-diamine can perform stepwise reactions, enabling post-functionalisation following the formation of COF networks. The macromolecules based on 5'-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-[1,1':3',1''-terphenyl]-4,4''-diamine exhibit high conjugation and semiconducting properties. They find applications in electroluminescent cells and OLEDs.

Owing to its non-linear structure, 5'-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-[1,1':3',1''-terphenyl]-4,4''-diamine is also employed in the synthesis of macrocycles. These macrocycles are capable of hosting guest-hole interactions within their tailored cavity sizes.
