    Highly ordered nanorods of CdCl2·H2O were found to grow on the Langmuir film surface of the sandwich-type (phthalocyaninato) [tetrakis(4-pyridyl)porphryrinato] cerium double-decker complex [Ce(Pc)(TPyP)]. Experimental results revealed the important template role the Langmuir monolayer of [Ce(Pc)(TPyP)] played during the formation of well orientated CdCl2·H2O nanorods because of the metal–ligand coordination interaction between the Cd2+ cations in the subphase solution and the pyridyl groups of the double-decker molecules. The CdCl2·H2O nanorods formed were characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM), high resolution transmission electron microscopy (HRTEM), selected area electron diffraction (SAED), atomic force microscopic (AFM) and X-ray photoelectron spectroscopy (XPS).
