摘　　要：Organic diradicaloids have unusual open-shell nature and properties and are promising materials for organic electronics,spintronics,energy storage and nonlinear optics.In this review,we focus on indeno-type organic diradicaloids and summarize their molecular design and synthesis,as well as topological structures,open-shell characters and diradical properties.The molecular systems are classified into indenofluorenes and diindenoacenes,indeno-based molecules with one-dimensional,two-dimensional and unique topological structures,and heterocyclic indeno-based molecules.By constructing these various topologicalπ-skeletons with tunable conjugation modes and variation of atomic composition,their key open-shell parameters,such as diradical characters and singlet-triplet energy gaps,along with the optical,electronic and magnetic properties,as well as stabilities are efficiently modulated.More attention may be paid to accurate computational analysis,rational design and synthesis,and novel functions of indeno-type diradicaloids,which will promote the development of radical chemistry and materials.
