Conjugated Microporous Polymer Nanoparticles that Disperse in Water for Detection of Nitroaromatics

“…CMPs exhibit a high degree of flexibility in molecular design and photoelectric properties, allowing for the modification of conjugated backbones and nanopores through synthetic functionalization. The reactions for synthesizing CMPs include Yamamoto cross-coupling, Sonogashira-Hagihara cross-coupling, Suzuki-Miyaura cross-coupling, − Heck cross-coupling, and Schiff Base reaction . Due to their intrinsic microporosity and unique electronic structure, CMPs have found extensive applications in gas adsorption and separation, heterogeneous catalysis, energy storage, and especially fluorescence sensing. − However, their highly hydrophobic cross-linked structure hinders their dispersity in water, leading to challenges in achieving stable and efficient fluorescence sensing in the aqueous phase.…”
