Two near‐infrared (NIR) absorbing metallopolyynes of platinum ( P1 and P2 ) functionalized with a weakly electron‐donating fluorene unit and two strong electron acceptors (viz. benzo[1,2‐ c :4,5‐ c ′]bis([1,2,5]thiadiazole) and [1,2,5]thiadiazolo[3,4‐ i ]dibenzo[ a , c ]phenazine) were synthesized and applied for NIR photovoltaic applications. With these designed weak donor–strong acceptor electronic traits, these metallopolymers possess narrow bandgaps of 1.54 and 1.65 eV and a low HOMO level of about 5.50 eV, thus inducing a power conversion efficiency up to 1% for bulk heterojunction solar cells at the NIR wavelength.
