Highly efficient and selective probes based on polycyclic aromatic hydrocarbons with trimethylsilylethynyl groups for fluoride anion detection
Two polycyclic aromatic hydrocarbons bearing trimethylsilylethynyl groups were designed and synthesized as new colorimetric and ratiometric fluorescent probes for fluoride anion. Both probes exhibit high specific selectivity and sensitivity for F− compared to other anions. When F− is added to the solution of the probe, the trimethylsilyl substituents can be removed immediately, and the color of the

Polycyclic fused aromatic pyrrole-based compounds, benzodipyrrole, naphthobipyrrole and their alkylated derivatives, were synthesized and studied electrochemically. Amongst these, naphthobipyrrole having a tetracyclic fused aromatic structure was electrochemically polymerized to give the homopolymer of naphthobipyrrole, poly(naphthobipyrrole), indicating good reactivity of α,α′-pyrrolic positions towards

The bridgingligands are laterally π-extended by anellating a pyrene (Ru2 -7
The synthesis and late-stage diversification of BN-embedded dibenzocorannulenes (B2N2-DBCs) based on one-shot halogenative borylation and successive cross-coupling reaction is reported. An organiclight-emittingdiode employing one of the derivatives as an emitter exhibited a high external quantum efficiency of 6.6 % and long operational lifetime of 907 h at an initial luminance of 1000 cd m−2.
