Quinazoline compounds have gained significant attention in the fields of agriculture and chemistry due to their diverse activities. In this study, we focused on a series of quinazoline derivatives (4a−l). The objectives involved multiple aspects, including preparation, evaluation of their agricultural bioactivity against the maize aphid (Rhopalosiphum maidis), estimation of the structure−activity relationships (SAR), and conducting molecular docking analysis. The results of the agricultural bioactivities revealed that compound (4b) possesses the highest insecticidal activity, and the other compounds have good potential as insecticidal agents. We conducted the SARs and also molecular docking investigation to elucidate the binding modes and interactions of these compounds with target proteins relevant to the agricultural bioactivity. The docking results provided valuable information on the binding affinities and molecular interactions, aiding in the rationalization of the observed bioactivity trends. The enzyme, acetylcholinesterase (AChE), was docked with the 12 synthetic compounds (4a−l). Among these compounds, (4b), (4i), and (4e)exhibited the highest binding affinity, with docking scores (S) of −7.96, −7.83, and −7.73 kcal/mol, respectively. They were followed by compounds (4d) (S = −7.57 kcal/mol), (4c) (S = −7.53 kcal/mol), (4g) (S = −7.34 kcal/mol), (4f) (S = −7.23 kcal/ mol), (4h) (S = −7.14 kcal/mol), (4k) (S = −6.61 kcal/mol), (4j) (S = −6.57 kcal/mol), (4a) (S = −6.28 kcal/mol), and finally (4l) (S = −6.01 kcal/mol). These compounds were shown to have a variety of binding interactions within the 2ACE active site, as evidenced by protein−ligand docking configurations. This study gives evidence that those compounds have AChE-inhibitory capabilities and, hence, may be used for AChE-targeting development. Also, the findings in this study highlight the potential of these compounds as agricultural agents and provide valuable insights for the design and development of some quinazoline derivatives with enhanced bioactivity for crop protection.

Morphology control and hydrophilic modification are important strategies to improve the photocatalytic activity of polymers. In the present work, novel conjugated microporous polymers with hollow spherical structures (CMPs-HSs) are prepared using 1,3,5-triacetylene benzene and 2,8-dibromodibenzothiophene as monomers through Sonogashira−Hagihara crosscoupling reaction and hard template method. In order to improve the dispersibility of the as-prepared CMPs-HSs in water, the hydrophilic modification of the CMPs-HSs is performed based on the thiol-alkynes click reaction, and the corresponding hydrophilic modified polymer is denoted as CMPs-HSs-S. The band gaps of CMPs-HSs and CMPs-HSs-S are 2.15 and 1.96 eV, respectively. The photocatalytic degradation rate of CMPs-HSs-S to Rhodamine B (RhB 20 mg L −1 ) is 90% within 80 min, while the CMPs-HSs is only 59%. Under the same experimental conditions, the degradation rate of CMPs-HSs-S to methylene blue (MB 20 mg L −1 ) is 85% within 120 min, and the degradation rate of CMPs-HSs to methylene blue is only 41%. The results of photocatalytic experiments show that the photocatalytic performance of CMPs-HSs-S is significantly better than that of CMPs-HS, suggesting that hydrophilic modification is more conducive to the contact of CMPs-HSs-S with pollutants and the occurrence of a photodegradation reaction. In addition, the corresponding composite membrane materials (abbreviated as CCMPs-MHSs and CCMPs-MHSs-S) of the CMPs-HS and CMPs-HS-S were prepared by the method of carbonized treatment, and their solar-driven interfacial evaporation (SDIE) performance was also studied. Under 1 kW m −2 simulated sunlight irradiation, the solar evaporation rates of CCMPs-MHSs and CCMPs-MHSs-S are 1.38 and 1.41 kg m −2 h −1 and the photothermal conversion efficiencies are 81.5 and 84.6%, respectively. Therefore, considering the designable flexibility of CMPs, the CMPs-based novel materials have great application potential in the study of photodegradation of organic dyes, solar-driven interfacial evaporation, etc.

“…Due to their high photonic activity and extended conjugation, CMPs are attractive materials for adsorption and photodegradation of organic dyes in aqueous solutions [14,15]. However, most CMPs have certain requirements on the action environment [16,17]. For example, Cai needs to be in the presence of hydrogen peroxide and Li needs ultraviolet light to stimulate catalysis [17,18].…”

Conjugated microporous polymers (CMPs) have important applications in the fields of optoelectronics and sewage treatment due to their high specific surface area, broad visible absorption, processability and simple synthesis process. Biocompatibility, recycling, mass production and solar photodegradation are particularly important in wastewater treatment. Here, A CMP with a high specific surface area and a hierarchical pore structure (CPOP) was constructed based on 4,4′,4″-Tris(carbazol-9-yl)-triphenylamine (3CZ-TPA). Furthermore, a CMP-loaded wood aerogel (CPOP/wood aerogel) with physical adsorption, chemical degradation, bacterial inhibition and self-cleaning properties was prepared by in situ polymerization and used for wastewater treatment. The obtained CPOP/wood aerogel is highly biocompatible and easy to recycle. In addition, the inherent broad visible light absorption property of CPOP endows it with promising photocatalytic properties. Subsequently, we investigated the photocatalytic mechanism of CPOP, and the results showed that it was mainly affected by peroxyl radicals, which implied and confirmed its microbial self-cleaning for secondary cleaning of water pollutants. The reported studies on CPOP/wood aerogel provide a new direction for water purification materials with excellent adsorption, degradation and antibacterial properties.
