Modulation of material electronic profiles through metal doping is one of the common approaches in industry of semiconductors. Moreover, doping strategy also advances applications in the areas of optoelectronics, photocatalysis, photovoltaics, and even spintronics. Advancement in the field of metal-organic framework (MOF)-based semiconductors can be also associated with engineering of heterometallic metal nodes. In this talk, we will discuss the influence of MOF topology, secondary building block (SBU) nuclearity, presence of unsaturated metal sites, metal nature, and doping percentage on the electronic behavior of heterometallic MOFs. In particular, we focus on analysis of heterometallic frameworks possessing mononuclear, binuclear, and pentanuclear metal nodes. Combination of crystal structure analysis, X-ray photoelectron spectroscopy studies, optical data, conductivity measurements, charge analysis, and theoretical calculations revealed the incorporated metal–electronic structure relationships. Overall, these studies are among the first attempts to demonstrate the unrevealed potential of a metal doping for tailoring heterometallic MOFs electronic behavior, and we anticipate that they are going to provide a fundamental guidance for further development of the MOF-based semiconductors.<br/>
