【摘要】 合成了一系列四-[3-甲氧基-4-(N-咔唑)正烷氧苯基]卟啉钯(Pd-4Cn-TPP,n=4,6,8)化合物,将这3种钯卟啉化合物质子化后与介孔分子筛MCM-48组装,制备了氧气传感材料Pd-4Cn-TPP4+/MCM-48(n=4,6,8).该系列组装材料的发光可以被氧气明显猝灭,即使当氧气的体积分数只有0.1%时,组装体的发光猝灭程度也超过50%.3种组装氧气传感材料均具有很高的灵敏度(I0/I100>38)和快速的响应时间(t↓≤0.08 s).更多还原

【Abstract】 A series of palladium meso-tetrakis[3-methoxy-4-（N-carbazyl）n-alkyloxyphenyl]porphyrin（（Pd-4Cn-TPP）,n=4,6,8） were synthesized.Pd-4C4-TPP,Pd-4C6-TPP and Pd-4C8-TPP exhibit similar luminescent properties in solution and solid state.Three protonated palladium（Ⅱ） porphyrins Pd-4Cn-TPP⁴⁺ are assembled with mesoporous silica MCM-48,respectively,resulting in the assembly materials Pd-4Cn-TPP⁴⁺/MCM-48（n=4,6,8）.The luminescence of Pd-4Cn-TPP⁴⁺/MCM-48 can be extremely quenched by molecular oxygen.Even the volume fraction of oxygen is 0.1%, the luminescence intensity of Pd-4Cn-TPP⁴⁺/MCM-48 can be quenched over 50%.The high sensitivity(I₀/I₁₀₀>38) and rapid response time（t_↓≤（0.08 s）） were achieved.更多还原
