英文摘要a mechanically interlocked light-harvesting system [3]rotaxane a has been synthesized in high yield through cu(i)-catalyzed azide-alkyne cycloaddition; the hexyl-substituted truxene units are introduced into the wheels as donors and an oligo(paraphenylenevinylene) (opv) unit into the axis as the acceptor. the structure and the purity of [3]rotaxane a were confirmed by (1)h and (13)c nmr spectroscopy and esi hrms. the azide-alkyne cycloaddition is demonstrated to be an efficient stoppering method in the synthesis of the rotaxane containing dibenzo[24]crown-8 and dibenzyl ammonium units. detailed steady-state uv/vis absorption, photoluminescent, and time-resolved fluorescence spectroscopy were performed to investigate the photophysical properties of [3]rotaxane a and its reference compounds in solution and as thin films. even in dilute solution, efficient energy transfer from the truxene-functionalized wheels to the opv-based axis, through the dibenzo[24]crown-8 and dibenzyl ammonium interaction, is observed in [3]rotaxane a. the unique topology of [3]rotaxane a not only efficiently promotes the intramolecular energy-transfer process, but also prevents intermolecular aggregation in the solid state. the new antenna system opens up the possibility of controllable light-harvesting molecular machines or other optoelectronic devices on the nanometer scale.
