Abstract:

An important intermediate of D-A-D polyfluorene derivative, 2,7-bis(4,4,5,5-tetramethyl-1,3,2-dioxaboralan-2-yl)-9,9-dioctylfluorene, was synthesized from Suzuki coupling polymerization. One- and two-dimensional NMR techniques (i.e., 1H NMR, 13C NMR, DEPT, 1H-1H COSY, HMQC and HMBC) were used to assign the proton and carbon chemical shifts and to elucidate the structure of the compound.

Key words: NMR, assignment, 2D NMR, polyfluorene derivatives
