Abstract

Arylamine polymers were prepared via the facile one-step addition condensation of N,N′-diphenyl-N,N′-bis(4-methylphenyl)-1,4-phenylenediamine and 4-methoxytriphenylamine with paraldehyde. The polymers were highly soluble in common organic solvents. The non-conjugated arylamine polymer structure was characterized and found to form tough, homogeneous, amorphous layers with a glass transition temperature above 200 °C on a substrate by a simple spin-coating process. The polymer layers exhibited a hole mobility of the order of 10−5 cm2 V−1 s−1, which was comparable with those of previously reported arylamine polymers, and a highest occupied molecular orbital level of −5.38 eV appropriate for the hole-transporting layer of perovskite solar cells. The perovskite cells fabricated with the polymers gave a photovoltaic conversion efficiency of 16.0%.
