Spin-lattice relaxation of copper and vanadyl porphyrins in extended molecular framework materials
Abstract
Spin-lattice relaxation times (T₁) of Cu(II) and VO(IV) porphyrins in extended framework materials (covalent, hydrogen-bonded, and metal–organic frameworks) are investigated as prototypical molecular spin qubits. All framework materials studied here exhibit longer T₁ values than the corresponding metal tetraphenylporphyrin (MTPP) crystals.
