The novel ensuing functionalities of complex nanostructures are driving the surging interest in their conceptualization and realization. Despite the significant synthetic developments in multicomponent hybrid nanostructure (HNS) formation, development of selective chemistry to tune the properties of HNSs will always be one of the major demands in colloidal synthesis. Synthesis of complex HNSs with a predicted morphology is particularly challenging using traditional strategies as the seeded growth due to surface chemistry limits. In the present work, we investigate the role of a metal oxide (MO) domain on the insertion of a CdS nanorod via a solution-liquid-solid mechanism between heterodimers of Au-MO. By choosing different compositions and crystalline structures for the MOs (namely, Fe3O4 and MnO), we demonstrate and explore the mechanism that allows the MO to dictate the chemoselective growth of the CdS domain. Additionally, a kinetic study unravels the role of the crystalline structure at a CdS-Fe3O4 interface on the final HNS shape.
