摘　　要：Designing and creating molecular structures with precisely organized organic chromophores as donors and acceptors are critical for exploring photo-induced charge transfer properties.Donor and acceptor moieties can be incorporated to the confined skeletons of organic cages,thereby offering opportunities tomanipulate excited state characters for the development of novel photofunctional molecules.Herein,we present the convergent synthesis and photophysical characterizations of an organic cage with anisotropic skeleton.The strained and rigid cage can be concisely prepared by connecting two distinct macrocycles through axial stacking strategy,featuring triarylamine and amide moieties as separate donors and acceptors,respectively.Steady-state and time-resolved spectra reveal photo-induced through-space intramolecular charge transfer and long-lived charge separation,thereby verifying the cage’s photocatalytic utility for efficient hydrogen production.
