Metadynamics
This increase in H-bonds indicates that the carrier’s solubility has increased due to functionalization. Therefore, it can be inferred that hydrogen bonding was the primary driving force in the adsorption process of pharmaceutical pollutant molecules on the COFs’ surface. Finally, it is essential to acknowledge that many other published papers have used MD to study biological phenomena, and our findings are consistent with these studies. Figure 9 depicts a schematic representation of both the COFs/F-COFs and their monomer structures.

According to the free energy surface analysis, the pharmaceutical molecule must overcome an energy barrier in order to reach the global minimum. The obtained results at both temperatures showed that F-COF&COFs are effective substrates for adsorbing pharmaceutical pollutant molecules in wastewater. This analysis compares the ability of COFs to provide sufficient accessible areas for removing pharmaceuticals. Generally, when pharmaceutical pollutant molecules are adsorbed onto COFs, they disperse less in water, resulting in a lower average SASA value. However, in this study, a lower contact area between PPMs and COFs indicates more significant adsorption of pharmaceutical pollutant molecules, which is desirable.

This analysis serves as an indicator of the precision of our design and confirms that our systems are in a state of conformational equilibrium. The density map along the z-axis of the simulation box for water molecules and PPMs/F-COFs&COFs are investigated to determine the position of PPMs relative to the F-COFs surface, and the probability of water being present at a particular location. Aquatic systems often serve as the primary recipients of these pharmaceutical discharges. The increasing occurrence and concentration of these compounds in the environment raise significant concerns, particularly due to their potential adverse effects27. Consequently, water eutrophication poses a severe environmental threat with negative repercussions on aquatic life and, by extension, the entire ecological cycle29.

Architectural design of 2D covalent organic frameworks (COFs) for pharmaceutical pollutant removal
To utilize COF materials for water treatment, it is imperative to ensure their stability when exposed to water. Furthermore, it is noteworthy to investigate various environmental factors, including reaction time and temperature, in order to gain a comprehensive understanding of the removal mechanism58. Informaticists should additionally design accessible platforms that allow primary caregivers to connect with and learn from other caregivers while minimizing exposure to sensitive or emotional content as indicated by the user. 7, the F-COFs have excellent adsorption performance, with the pharmaceutical pollutant molecules having the lowest contact area with the solvent.
This work demonstrated that the F-COFs/COFs substrates of all examined systems spontaneously adsorb pharmaceutical pollutant molecules. Furthermore, it was found that the adsorption of pharmaceutical pollutant molecules is higher in the inner and outer cavities of COFs functionalized form with three functionalized hydroxyl groups in comparison to the pristine system. Indeed, the PPMs/F-COFs systems exhibit stronger hydrogen bond formations, leading to a higher propensity for pharmaceutical pollutant molecules to adsorb onto F-COFs surfaces compared to pristine COFs. The analysis of hydrogen bonding confirms that pharmaceutical pollutant molecules display a superior capability to establish hydrogen bonds with F-COFs when compared to the pristine COFs. In the environment temperature, the DEG molecule shows the most tendency for adsorbing on both investigated substrates, whereas with increasing temperature, the tendency of EMC and CMC drugs for adsorbing on COFs and F-COFs, respectively, will be increased.
Short-term Access
The migration capability of PPCPs over long distances and their potential for decomposition contributes to extensive pollution, resulting in the depletion of dissolved oxygen and the subsequent collapse of aquatic ecosystems. Therefore, the presence of PPCPs in water systems can adversely affect human health and ecosystems16,17, presenting significant risks18,19. Hence, removing these pollutants from water sources is paramount in safeguarding the environment and public well-being.
The calculation of the interaction energies is crucial in gaining a deep understanding of the adsorption mechanism of the pharmaceutical pollutant on the COF carriers. A higher absolute value of interaction energy indicates stronger interactions between pharmaceutical pollutants and COFs/F-COFs. The greater adsorption of pharmaceutical pollutants onto COFs results in the energy of the simulated systems becoming more negative.
During the simulations, the average contact area of pharmaceutical pollutant molecules increases as the contact area between pharmaceutical pollutant molecules and COFs increases (see Fig. 4 and Supplementary Fig. 7). This creates favorable conditions for the interaction of pharmaceutical pollutant molecules with substrates, leading to a more significant accumulation of PPMs around the COF structure. PPCPs can be classified based on their purpose and their characteristics30. For instance, anti-inflammatory drugs, such as dexamethasone (DZM)30, diclofenac31, indomethacin32, ibuprofen33, naproxen34, and ketoprofen34 are commonly used to relieve pain and reduce inflammation35,36. Antibiotics, including clarithromycin (CMC)37,38, erythromycin (EMC)39, azithromycin (AZM)40, danofloxacin (DAN)41, sulfamethoxazole (SMZ)42, orbifloxacin (ORB)43, ciprofloxacin (CIP)44, tetracycline (TC)45, and cefotaxime (CTX)46, are used to fight bacterial infections.
