 Abstract: The synthesis of a ferromagnetic heterostructured material consisting of a CdSe@CdS nanorod attached to a single dipolar cobalt nanoparticle (CoNP) into a “matchstick” morphology is reported. CdSe@CdS nanorods were modified by an activation reaction with Pt(acac)2 which enabled selective one-sided deposition of a dipolar metallic CoNP-tip via the thermolysis of Co2(CO)8 in the presence of polystyrene ligands. Small (<2 nm) PtNP-tips on CdSe@CdS nanorods were found to be responsible for the selective deposition of CoNP-tips onto one terminus per nanorod. The influence of the Pt-activation step for cobalt tipping was investigated by examination of numerous conditions and characterization of intermediates and materials using transmission electron microscopy and synchrotron X-ray diffraction.
