摘要

Host-guest interactions of multifarenes with naphthylamines and naphthols were investigated. Decreased fluorescence emission of the guests upon addition of increasing amounts of multifarene hosts confirmed the formation of host-guest complexes in a ratio of 1:1. Non-linear curve fitting showed moderate association constants of between (5.2 +/- 0.7) x 10(3) and (2.3 +/- 0.6) x 10(4) L mol(-1). The stabilities of the complexes were dependent upon both the ring size of the host and the structure of the guest. (HNMR)-H-1 spectra indicated that the interactions involved hydrogen bonds between the amine or hydroxyl groups of the guests and the hydroxyl groups of the multifarenes. Molecular simulations were performed to provide the microcosmic structures of the interaction complexes.
