摘要：The development of 1D stimuli-responsive ultrathin organic nanomaterials (UTONMs)-based hybrid nanocomposites with tailored functions is necessitated to construct hybrid catalysts with adjustable catalytic performance. Herein, the self-assembly of ternary amphiphilic alternating azopeptoids into micron-scaled ultrathin peptoid nanobelts (PNBs) is reported with a thickness of approximate to 2.2 nm. The pendants hydrophobic conjugate stacking mechanism is accountable for the formation of 1D long-ranged-ordered nanostructure, whose thickness is highly dependent on the length of the suspended side-chains. The photo-triggered reversible transition from PNBs to nanospheres (approximate to 92 nm) is rendered by the photo-isomerization of azobenzene moiety upon alternating irradiation with UV and visible lights. Moreover, the carboxyl-modified aggregates are employed as supports to load Pd nanoparticles, successfully preparing hybrid nanocomposites. As a proof-of-concept experiment, the catalytic activity of both control and these hybrid nanocomposites are evaluated toward chemo-enzymatic cascade catalysis for 3,3 ',5,5 '-tetramethylbenzidine oxidation with in situ UV-vis spectroscopic monitor. Compared to nanospheres-based systems, PNBs-based nanocomposites exhibited larger catalytic performance, attributable to the ultrathin nanostructures and subsequent ultrahigh specific surface area. The photo-controllable recyclable catalytic activity is effectively modulated using the alternative irradiation with UV and visible lights for three cycles. The work paves an appealing avenue to prepare UTONMs-based stimuli-responsive hybrid nanocomposites with controllable performance. 1D micron-scaled ultrathin peptoid nanobelts (PNBs) with a thickness of 2.2 nm are generated using the self-assembly of ternary amphiphilic alternating azopeptoids, exhibiting a photo-triggered reversible transformation from PNBs to nanospheres. The ultrathin nanostructures and photo-responsive ability of PNBs are advantageous for constructing stimuli-responsive hybrid nanocomposites with a photo-controllable catalytic performance. image
