The sensitive and selective identification of nitroaromatic explosives industrially ubiquitous nitrates, which are harmful to the environment, is crucial from viewpoints security environmental remediation. New multifunctional fluorescent porous materials that can sense nitro-explosives nitrates under continuous development. To this end, study synthesizes 3,10,15-/-3,10,16-tribromotrinaphtho[3.3.3]propellane (TBP) 4,7-bis(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-2,1,3-benzothiadiazole (BB) employs them as dual building blocks prepare a conjugated microporous polymer (denoted CMP–TBP–BB) via Suzuki–Miyaura borylation polycondensation. CMP–TBP–BB synthesis strategy takes advantage donor acceptor characteristics propeller-like trinaphtho[3.3.3]propellane moiety in TBP benzothiadiazole group BB, respectively. unusual two-dimensional conformation CMP with propeller–array-structured monomers helps position π components crystalline layers establishes aligned conduction pathways. exhibits outstanding fluorescence characteristics. Its distinctive skeleton exploited fabricate highly donor–acceptor blocks, typically considered challenging task. acts sensor for selectively sensitively detecting electron-deficient metal nitrates. Specifically, responsive 2,4,6-trinitrophenol Fe(NO3)3 at parts per million levels, results combined experimental theoretical investigations its sensing properties highlight potential CMP-based probe. Additionally, dual-function probe remarkable temperature-sensing behavior owing high linearity between intensity temperature, making it an excellent thermometer.
