Overview
Related Products

Tris[4-(5-formyl-2-thienyl)phenyl]amine (TTA-TPA) is a derivative of triphenylamine with thiophene-2-carbaldehyde function groups at the positions that are opposite to the central nitrogen. Tris[4-(5-formyl-2-thienyl)phenyl]amine finds application in OLEDs, organic solar cells and covalent organic frameworks (COFs). With both triphenylamine core and extended thienyl groups, π-conjugated structures derived from tris[4-(5-formyl-2-thienyl)phenyl]amine is electron rich, serving as either hole transporting layer (HTL) or photoactive dyes for organic electronic devices. With three peripharal aldehyde end groups, it could form imine linkers with amines through Schiff base condensation reaction for the construction of COFs.

Bulk-heterojunction solar cell based on a solution-processable three-dimensional molecular architecture comprising tris[4-(5-formyl-2-thienyl)phenyl]amine and 1-(2-ethylhexyl)-4-methyl-2,6-dioxo-1,2,5,6-tetrahydropyridine-3-carbonitrile achieved device PCE of 4.76% with [6,6]-phenyl-C61-butyric acid methyl ester (PC61BM) as the acceptor.
