Surface-induced enantiomorphic crystallization of achiral fullerene derivatives in thin films

Abstract

Chiral induction: surface-segregated monolayers of chiral molecules induce the enantiomorphic crystallization of achiral fullerene derivatives in thin films.

Chiral Open-[60]Fullerene Ligands with Giant Dissymmetry Factors

“…Thereby, the fullerene chirality has been thrust into the spotlight, and excellent chiroptical features of fullerene-based materials have been found in succession over the past few years . For instance, in 2020, Tajima and co-workers achieved an enantiomorphic crystallization of organic semiconducting molecules in thin films using chiral methano[60]­fullerenes as surface modifiers . This approach is capable of producing thin-film organic semiconductors with a high structural order in organic electronic devices.…”

“…7 For instance, in 2020, Tajima and coworkers achieved an enantiomorphic crystallization of organic semiconducting molecules in thin films using chiral methano[60]fullerenes as surface modifiers. 8 This approach is capable of producing thin-film organic semiconductors with a high structural order in organic electronic devices. In 2021, Fuchter and co-workers found the fast and intense photocurrent responses from chiral bis(methano) [60]fullerenes used as single-enantiomer electron acceptors in organic field-effect transistors, showing a potential application into circularly polarized light (CPL)-detecting devices.…”

Surface Segregated Monolayers of Fluoroalkylated Rod-like Molecule for Asymmetric Charge Transport at Organic Semiconductor Interfaces

“…18,19 Third, structural similarity might be crucial for the previously observed SSM-induced crystallization within the film bulk. 20,21 Nevertheless, SSM molecular design is not restricted to semiconductors; insulating molecules with simpler structures could pioneer new applications for SSMs. With thoughtful molecular design to enhance the 2D interactions in the SSM, the formation of a highly ordered SSM could be achievable.…”

Production of Organizational Chiral Structures by Design

“…Surface chirality is an area of growing interest, due to its intriguing scientific significance and many potential applications, such as chiral sensors, circularly polarized light emission, enantioselective separation, crystallization, and catalysis. − In addition to the well-known molecular chirality, surface chirality can also arise from achiral molecules, as certain absorbed conformations induce chirality. , A less studied form of surface chirality is organizational chirality, which arises solely from the arrangement of the molecules on the surface . Therefore, both chiral , and achiral molecules ,− have been utilized to form organizational chiral structures.…”
