Two types of luminescent fluorene-based organoboron quinolate polymers, PFB2Q2 and PFBQ, have been prepared by boron-induced ether cleavage reaction. PFBQ has a structure with quinolato substituted boron embedded in the main chain, while in PFB2Q2, both the quinolato moieties and the boron atoms are placed in the main chain. All the resulting polymers are readily soluble in common organic solvents and have been characterized by multinuclear NMR spectroscopy. They show good chemical stability and are thermally stable to >300 °C. The photoluminescence properties of PFB2Q2 are strongly dependent on the conjugated bridge connecting the two quinolato groups. With a biphenyl linker yellow green emission was observed, whereas the Th-Ph-Th linker gave (weak) orange emission. The polymer with the Th-Ph-Th linker shows an unusual wavelength and concentration-dependent emission.
