Replacing conventional inorganic materials and semiconductors, the state-of-the art molecular spintronics aims at developing a new generation of spintronic devices-based on molecular materials. Molecular systems offer exceptionally long spin relaxation times and enhanced quantum effects in the single molecule limit, enabling them for integrating into spintronic structures. The potential offered by molecules in terms of functionality, performance, and miniaturization for spin-based devices has also motivated the search for novel classes of magnetic molecular materials with multifunctional properties. For example, the development of porous magnetic materials with electrical conductivity has been a great interest in the past decade because of the intrinsic magnetism, electrical conductance, and porosity within a single molecular system, which serves as a multifunctional platform for magnetic separation, magnetic conductors, magnetic molecular sensing, and low-density magnets. In this research we have developed porous magnetic conductors with short-range ordering of superparamagnetic and conducting properties by manipulating the isoreticular nature of metal-organic frameworks (MOFs). These MOF structures with geometrically frustrated magnetic units and their conductive behavior could be the next candidates for next generation quantum spintronics devices, quantum computing memory storage, and quantum spin liquids.
