Supramolecular assemblies (PS-b-P4VP(AzoR)) are fabricated by hydrogen-bonding azobenzene derivatives (AzoR) to poly(4-vinyl pyridine) blocks of polystyrene-block-poly(4-vinyl pyridine) (PS-b-P4VP). PS-b-P4VP(AzoR) forms phase separated nanostructures with a period of ~75–105 nm. A second length scale structure with a period of 2 µm is fabricated on phase separated PS-b-P4VP(AzoR) by laser interference ablation. Both the concentration and the substituent of AzoR in PS-b-P4VP(AzoR) affect the laser ablation process. The laser ablation threshold of PS-b-P4VP(AzoR) decreases as the concentration of AzoR increases. In PS-b-P4VP(AzoR) with different substituents (R= CN, H, and CH3), ablation thresholds follow the trend: PS-b-P4VP(AzoCN)<PS-b-P4VP(AzoCH3)<PS-b-P4VP(AzoH). This result indicates that the electron donor group (CH3) and the electron acceptor group (CN) can lower the ablation threshold of PS-b-P4VP(AzoR).

在不同工艺阶段通过可控调整吸附剂性质实现高效吸附和脱附是非常有吸引力的。然而,传统的吸附剂由于其固定的活性位点而难以实现这一目标。因此,我们将具有顺反异构体的偶氮苯衍生物引入铈掺杂的介孔氧化硅中,构筑了一种光响应智能吸附剂。这些光响应基团具有“分子开关”的作用,能够遮蔽或暴露活性位点,从而实现吸附剂的高效吸附和脱附。掺杂了铈元素的吸附剂可以提供额外的活性位点,进而提高吸附剂吸附性能。结果表明,偶氮苯顺式异构体能有效遮蔽活性位点,使吸附剂对亚甲基蓝(MB)和亮蓝(BB)进行选择性吸附,而其反式异构体则使活性位点暴露,导致吸附质释放。这些智能吸附剂通过光刺激能够可控地实现选择性吸附和高效脱附。此外,经过5次循环后,材料的性能保持良好。
