“…The aggregated carriers and unreleased pesticides become new environmental hazards. [ 17 ] Although endowing pesticide delivery systems with magnetism is an effective strategy to solve the recycling problem, [ 13b,18 ] the recovery rate cannot be maintained at a high level for larger‐scope applications. Thus, it is still a challenge to develop an SRCRS with flexible control, precise release, easy recovery, and suitability for future pesticide application in aquatic environments.…”

The precise, controllable, and safe application of pesticides can effectively reduce pesticide consumption and minimize chemical pollution at the source. Here, a light‐responsive controlled‐release system with flexible control, precise release, easy recovery, and suitability for future pesticide application in aquatic environments is proposed. The system precisely controls the release of pesticides through a light‐responsive composite nanochannel membrane (CTC@SNM/PET) with reactive coumarin derivatives (CTC) as gating molecules. The prepared nanochannel membrane has an ultrathin thickness of 67.5 nm and well‐ordered vertical nanochannels with a uniform size of 1.9 nm, providing a prerequisite for precise molecular gating and high permeability for mass transport. CTC monomers can realize cycloaddition/cyclocracking and nanochannel closing/opening to control the release of pesticides by controlling 365/254 nm ultraviolet light irradiation. As a proof of concept, the light‐responsive controlled‐release system based on CTC@MSF/PET against Saprolegnia parasitica achieves an inhibition rate of more than 95% and reduces pesticide residues by 56.5% compared to the control group. The proposed membrane system has great application potential to easily enable remote, quantitative, timed, and positioned pesticide application, thereby reducing pesticide residues and providing a prospective approach to reducing environmental and human risks.

“…15,16 For instance, compared with spherical carriers, the rod-shaped CNCs have large specific area, facilitating deposition and retention on the surface of foliage. 17,18 In turn, the large specific surface area increases pesticide loading capacity and reduces the losses. [19][20][21] In addition, CNC's abundant surface hydroxyl groups are suitable for modification and binding.…”

“…[18] There are several reports in literature regarding the development of bio-based safe pesticides but their synthesis is not convenient (multistep, drastic reaction conditions). [19,20] In contrast, PBI-SAH building block is easy to prepare and is highly fluorescent in aqueous media. Contrary to the non-fluorescent pesticides (such as CPF), fluorescent pesticides are beneficial in terms of easy detection of their residues in water bodies/soil/food items.…”

Supramolecular assemblies of perylene bisimide derivative (PBI‐SAH) have been developed which show ‘turn‐on’ detection of chlorpyrifos in aqueous media, apple residue and blood serum. Differently from the already reported fluorescent probes for the detection of CPF, PBI‐SAH assemblies also show affinity for acetylcholinesterase (AChE) which endow the PBI‐SAH molecules with mixed inhibitory potential to restrict the AChE catalysed hydrolysis of acetylthiocholine (ATCh) in MG‐63 cell lines (in vitro) and in mice (in vivo). The molecular docking studies support the inhibitory activity of PBI‐SAH assemblies and their potential to act as safe insecticide with high benefit to harm ratio. The insecticidal potential of PBI‐SAH derivative has been examined against Spodoptera litura (S. litura) and these studies demonstrate its excellent insecticidal activity (100 % mortality in nineteen days). To the best of our knowledge, this is the first report regarding development of PBI‐SAH assemblies which not only detect chlorpyrifos but also mimic AChE inhibitory activity of CPF to show promising aptitude as safe insecticide.
