A Strained Donor‐Acceptor Carbon Nanohoop: Synthesis, Photophysical and Charge Transport Properties
Herein, we report the synthesis of a novel intramolecular donor‐acceptor (D−A) system ([12]CPP‐8TPAOMe) based on cycloparaphenylenes (CPPs) grafted with eight di(4‐methoxyphenyl)amino groups (TPAOMe) as donors. Compared to [12]CPP, D−A nanohoop exhibited significant changes in physical properties, i...

Summary: | Herein, we report the synthesis of a novel intramolecular donor‐acceptor (D−A) system ([12]CPP‐8TPAOMe) based on cycloparaphenylenes (CPPs) grafted with eight di(4‐methoxyphenyl)amino groups (TPAOMe) as donors. Compared to [12]CPP, D−A nanohoop exhibited significant changes in physical properties, including a large redshift (>78 nm) in the fluorescence spectrum and novel positive solvatofluorochromic properties with a maximum peak ranging from 484 nm to 546 nm. The potential applications of [12]CPP‐8TPAOMe in electron‐ and hole‐transport devices were further investigated, and its bipolar behavior as a charge transport active layer was clearly observed.
We present a novel intramolecular donor‐acceptor (D−A) system ([12]CPP‐8TPAOMe) based on cycloparaphenylenes (CPPs) grafted with eight di(4‐methoxyphenyl)amino groups (TPAOMe) as donors. This D−A nanohoop exhibits positive solvatofluorochromic properties and has potential applications in electron‐ and hole‐transport devices. |
