Multifunctional porous Tröger's base polymers with tetraphenylethene units: CO2 adsorption, luminescence and sensing properties

摘要: Luminescent porous organic polymers have shown potential applications in sensing, light-harvesting, photocatalysis and photo-voltaic or electronic devices. In this paper, a luminescent Troger's base polymer (LMOP-15) with tetraphenylethene unit has been synthesized by simple method through the reaction of 1,1,2,2-tetrakis(4-aminophenyl)ethene dimethoxymethane acid solution at room temperature. The N2 adsorption LMOP-15 77 K reveals type I isotherm microporous materials, calculated Brunauer–Emmett–Teller surface area is 484 m2 g−1. CO2 uptake capacity 273 1 bar 48.8 cm3 g−1, while isosteric heat for reaches 53.7 kJ mol−1 due to presence moiety. CO2/N2 selectivity from initial slopes isotherms up 61.7. also exhibits strong green luminescence (λmax = 517 nm) ethanol suspension. Furthermore, shows highly selective fluorescence quenching detection abilities Cu2+ ions picric acid.
