9'-fluorene] (10), and 2'-[spiro[benzo[c]fluorene-7,9'-fluoren]-2'-yl] spiro[benzo[c]fluorene-7,9'-fluorene] (11) were successfully prepared from the corresponding halogen and boronic acid derivatives through the Suzuki coupling reaction, respectively. Chemical structures were confirmed by H nuclear magnetic resonance (NMR), C NMR, Fourier transforminfrared spectrscopy, mass spectroscopy, and elemental
