Abstract:
A novel conjugated microporous polymer based on perylene tetraanhydride bisimide (DP2A2) has been synthesized through Sonogashira-Hagihara cross-coupling polymerization of tetrabromo-substituted perylene tetraanhydride bisimide derivative (DPBr2ABr2) with 1,4-diethynylbenzene, whose Brunauer-Emmett-Teller (BET) specific surface area is about 378 m2 g-1. The fluorescence quenching behaviors of the DP2A2 were investigated. It is found that the DP2A2 shows high sensitivity and selectivity to tracing o-nitrophenol (o-NP) in THF with KsV constant of 2.00 × 104 L mol-1. The detection limit (LOD) is 1.50 × 10-9 mol L-1. The possible sensing mechanism for the luminescent quenching of DP2A2 towards o-NP exciting at 365 nm was considered the donor-acceptor electron transfer mechanism, which is a combined result from both dynamic (collisional) and static quenching. Moreover, the static quenching process is dominant for DP2A2.

Nucleoproteins are protein complexes that contain nucleic acids, categorized as deoxyribonucleoproteins (DNPs) or ribonucleoproteins (RNPs) respectively. The nucleosome is a typical example of a DNP where nuclear DNA is associated with histone proteins. The major antigen for the Covid-19 virus SARS-CoV is an RNP that is critical...
