Three new polymers were obtained through an in situ chemical reaction of the matrix conjugated polymer ( PPQF ) with ortho‐ amine compounds. By controlling the conjugation degree of diamine compounds, the emission of PPQF was tuned from weak blue to bright blue, green, and orange for PFBQ , PFBP and PFNP , respectively. The photoluminescence efficiencies were also improved in the same tendency, and the LUMO levels were gradually decreased from −2.76 and −3.12 to −3.40 eV, which was beneficial for electron injection and transport in electronic devices. Thus, a dual tuning for the emission color and electron injection properties were realized through an in situ chemical reaction, which is a novel strategy to design and construct new valuable polymers from one reactive matrix polymer.
