Covalent organic frameworks (COFs) show great potential as drug delivery systems (DDSs) due to their customizable structures, stability, and capacity for pore surface functionalization. However, natural hydrophobicity limits dispersion in water, posing challenges biological applications. We address this issue by initially reducing a COF (Az-COF) an amine-linked form (Az-AL-COF) subsequently sulfonating it obtain Az-AL-SO3H-COF, water-dispersible derivative. Water contact angle (WCA) analysis confirmed increased hydrophilicity across the series of 84.5, 61.2, 54.7° Az-COF, Az-AL-COF, respectively. Using doxorubicin (Dox) model drug, modified COFs exhibited pH-sensitive release, with greater release at acidic pH (5.6) compared neutral (7.4). Cytotoxicity assays revealed that Az-AL-SO3H-COF was biocompatible normal cells (MCF-10) while effectively suppressing growth cancer (MDA-MB-231). The Dox-loaded sulfonated (Dox@Az-AL-SO3H-COF) showed selective cytotoxicity against cells, highlighting its pH-responsive, DDS treatment.

Abstract The [4+4]-type Covalent Organic Frameworks material TAPP-TFPB-COF was synthesized by using 1, 2, 4, 5-Tetrakis-(4-formylphenyl) benzene (TFPB) and 5,10,15,20- Tetra(p-amino-phenyl) porphyrin (TAPP) as monomers via Schiff base reaction. macroscopic structure is a two-dimensional layered assembled stacked in layers to form three-dimensional with micrometer size. Its pore size 1.20 nm regular its specific surface area 1107.3 m 2 g − 1 . It has good adsorption capacity for the model dye RhB at room temperature. In addition, could continue degrade photocatalysis under visible light irradiation after saturation of adsorption. had stability reusability. able achieve continuous removal dark conditions.
