A novel amphiphilic rod-coil organometallic oligomer with o-ferrocenylcarbonyl benzoic acid (FcBA) as the hydrophobic short-rod and with methoxy poly (ethylene glycol) (mPEG) as the hydrophilic coil chain has been obtained and the self-assembly behavior of the obtained oligomer was investigated under different initial concentrations. It was found that besides spherical and vesicle assemblies, a new type of morphology, twisty wormlike shape, was formed in the process of self-assembly and the π-π interaction between ferrocene and benzene ring was discussed.
