A non-fullerene acceptor polymer includes a structure represented by formula (I). Accordingly, the non-fullerene acceptor polymer is formed by using phenyl or its derivatives as an end group. Be compared with non-fullerene acceptor monomer and non-fullerene acceptor polymer with thiophene that the absorption wavelengths are being in the near infrared region, the non-fullerene acceptor polymer of present disclosure have stronger absorption and emission capabilities in the visible region. Therefore, the application field of non-fullerene acceptor polymer can be expanded. |
