Intercalation chemistry is of great importance in solid-state physics and chemistry for the ability to modulate electronic structures for constructing new materials with exotic properties. This ancient and versatile discipline has recently become prevailing in the synthesis and regulation of two-dimensional (2D) transition metal dichalcogenides (TMDs) with atomic thickness due to diverse host-guest configurations and their impact on the layered frameworks, which bring in extensive applications in electronics, optoelectronics and other energy-based devices. In order to prepare 2D TMDs materials with desired structure and properties, it is essential to gain in-depth understanding of the key role the intercalation chemistry plays in the preparation process. In this review, we provide a focused review on recent advances regarding 2D TMDs materials through intercalation exfoliation from the view of host, guest and solvent interactions. We comprehensively review the effect of intercalation chemistry on TMDs nanosheets synthesis and modification. We also try to clarify the interactions between host and guest from the aspects of lattice strain, interlayer distance and carrier density. Finally, a prospectus of the future research opportunities is provided for the intercalation chemistry of 2D materials. This article is protected by copyright. All rights reserved.
