The effects of the crosslinking position and degree of conjugation in perylene tetraanhydride bisimide microporous polymers on fluorescence sensing performance.

ABSTRACT: In this study, two fluorescence conjugated microporous polymers based on perylene tetraanhydride bisimide (DP₄A₀ and DP₄A₂) were prepared via Sonogashira-Hagihara cross-coupling polymerization for the efficient detection of o-nitrophenol (o-NP). They were well characterized via FT-IR, solid state ¹³C NMR, elemental analysis, and other material characterization techniques. The experiments proved that both CMPs possess high thermal and chemical stability and a porous nature with Brunauer-Emmett-Teller (BET) specific surface areas of 41.3 and 402.1 m² g^-1. Importantly, owing to signal amplification by the conjugated skeleton, DP₄A₀ and DP₄A₂ exhi
