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-TPP^+/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(t1≤0.08s).
A series of palladium meso-tetrakis [ 3-methoxy-4-( N-carbazyl ) n-alkyloxyphenyl ] porphyrin (Pd-4Cn-TPP, n =4, 6, 8 ) were synthesized. Pd-4CA-TPP, Pd-4C6-TPP and Pd-4C8-TPP exhibit similar luminescent properties in solution and solid state. Three protonated palladium( Ⅱ ) porphyrins Pd-4Cn-TPI^4+ are assembled with mesoporous silica MCM-48, respectively, resulting in the assembly materials Pd-4Cn- TPP^4+/MCM-48 ( n = 4, 6, 8 ). The luminescence of Pd-4Cn-TPP^4+/MCM-48 can be extremely quenched by molecular oxygen. Even the volume fraction of oxygen is 0. 1%, the luminescence intensity of Pd-4Cn-TPP^4+/ MCM-48 can be quenched over 50%. The high sensitivity ( I0/I100〉 38 ) and rapid response time ( t1 ≤ 0. 08 s) were achieved.
