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).

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.

Key words: Palladium(Ⅱ) porphyrin, Oxygen sensor, Mesoporous silica
