The polymerization reactions of ethynylfluorenol (EFl) in the presence of Rh(I), Pt(II), Pd(II) and WCl6 catalysts have been investigated. The polymer (PEFl) is air stable and soluble; in solution PEFl 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 PEFl suggest that I5- is the major doping species. An interesting reversible response to relative humidity variations is found for FeCl3-doped samples.

Abstract
The polymerization reactions of ethynylfluorenol (EFl) in the presence of Rh(I), Pt(II), Pd(II) and WCl6 catalysts have been investigated. The polymer (PEFl) is air stable and soluble; in solution PEFl 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 PEFl suggest that I5- is the major doping species. An interesting reversible response to relative humidity variations is found for FeCl3-doped samples.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
