The polymerization reactions of ethynylfluorenol (EFI) in the presence of Rh(I), Pt (II), Pd(II) and WCI 6 catalysts have been investigated. The polymer (PEFI) is air stable and soluble; in solution PEFI slowly releases some of the pendent groups which are converted into 9-fluorenone. Upon doping, enhancement of the conductivity up to about 10 orders of magnitude can be achieved. X.p.s. measurements performed on I2-doped PEFI suggest that 15 is the major doping species. An interesting reversible response to relative humidity variations is found for FeC13-doped samples
