Abstract
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.
