摘　　要：In recent years,the precisely controlled synthesis of chiral twisted molecular carbons has emerged as a forefront topic in the research of carbon materials.Molecular carbons refer to carbon nanomaterials synthesized with precision at the atomic level.Through rational design,rigid and stable chiral twisted structures can be synthesized.The exploration in the field of chiral twisted molecular carbons is key to fully understanding the various twisted configurations of carbon materials and delving into the relationship between structure design and functionality.This review explores chiral twisted configurations of carbon nanomater-ials such as nanographene,carbon nanobelts,carbon nanosheets,graphdiyne,etc.It emphasizes the role of photocyclization,Scholl reaction,and Diels–Alder reactions in achieving precise chiral control and discusses a range of innovative design strategies.These strategies have led to the development of various twisted structures,such as helical,propeller,and Möbius strip configurations.The introduction of chirality,combined with the inherent exceptional optical properties of nanocarbon materials,has facilitated the creation of materials with superior chiroptical performances.This advancement is driving applications in fields such as optoelectronics and chiral optics.
