Synthesis of water-stable and dispersible heterogeneous catalysts having high catalytic efficiency is more challenging compared with homogeneous due to their low dispersity, activity, spatial confinement active centers in bulk water. Herein, we are describing systematic studies for the development microconfinement participation aqueous micelles via temporal surface modification porous organic polymer derived from phosphine ligands. Detailed investigations using various techniques such as transmission electron microscopy (TEM), scanning (SEM), tensiometry, confocal laser (CLSM), fluorescence lifetime imaging (FLIM) have been used understand role micelles, reagents, materials generation microcolonies Two-color crossover experiments also performed exchange reagents or vice versa, materials. The surfactant-modified ligation stabilization palladium, which was evidenced by high-resolution (HR-TEM), high-angle annular dark-field (HAADF-STEM), X-ray photoelectron spectroscopy (XPS) analysis. act confined space catalysis water showcasing Suzuki-Miyaura cross-coupling reaction a ppm level Pd loading under mild conditions. catalyst found be recyclable five cycles; easy scale-up C-C couplings additional features. Moreover, these data provide an opportunity revising models micellar systems that underpin sustainable
