Abstract
Increasing attention has been given to arsenic-containing π-conjugated polymers. Herein, π-conjugated polymers with triphenylarsine (AsPh3) units in the main chains were synthesized from bis(p-bromophenyl)phenylarsine by Suzuki-Miyaura polycondensation. Compared with the model compounds, it was revealed that the conjugation length was expanded through the main chain. This is the first study on the synthesis and optical properties of main-chain-type AsPh3 polymers.
The first main-chain type triphenylarsine (AsPh3) polymers were synthesized by Suzuki-Miyaura polycondensation. The electronic and photophysical properties of the AsPh3 polymers were comparison with model compounds by experimental and computational methods. As a result, it was found that the conjugated systems were expanded through the arsenic atoms. The present AsPh3 polymers are promising as luminescent materials.
