PREPARATION AND PHOTOCHEMICAL PROPERTIES OF [2]ROTAXANES CONTAINING AN ANILINE MOIETY ENCAPSULATED BY CROWN ETHERS

[摘要]：This paper describes preparation of rotaxanes having an aniline moiety in the axle and crown ethers as wheels through an imine formation reaction and hydrogen-bond-guided self-assembly. UV-vis and emission measurements of the rotaxanes show that both absorption and fluorescence bands shift to longer wavelengths as compared to those of the unencapsulated axle component.
