Abstract

Abstract A series of phosphine oxide-functionalized polyfluorene derivatives, PFH-PO-40-1 (P1), PFH-PO-20-1 (P2), PFH-PO-10-1 (P3), and PFH-PO-1-1 (P4), were prepared via a palladium-mediated Suzuki cross-coupling reaction. The structures and purities of all polymers were fully characterized by 1 H and 13 C NMR, UV-vis and photoluminescent spectroscopy, gel permeation chromatography, and TGA/DSC. Their emission features ...
