介绍了一系列发光铂内消旋四{3,5-二[(N-咔唑基) n-烷氧基苯基]}卟啉 (Pt-8Cn-TPP, n-烷基 = (CH2)(n), n = 4、6 和 8) 的合成和光谱表征。将质子化的铂卟啉([Pt-8Cn-TPPH8](8+))与介孔二氧化硅MCM-48组装，得到组装材料[Pt-8Cn-TPPH8](8+)/MCM-48。 [Pt-8Cn-TPPH8](8+)/MCM-48 的发光可以被分子氧极度猝灭，具有非常高的灵敏度 (I-0/ I-100 > 5000) 和快速的响应时间 (0.04 s)，表明 [Pt-8C n-TPPH8](8+)/MCM-48 系统可用于开发高性能氧传感器。在该组装系统中，[Pt-8C8-TPPH8](8+)/MCM-48表现出最高的灵敏度。即使氧气浓度为0.1%，[Pt-8C8-TPPH8](8+)/MCM-48的发光强度也可被猝灭86%。
The synthesis and spectroscopic characterization of a series of luminescent platinum meso-tetrakis {3,5-di[(N-carbazyl) n-alkyloxyphenyl]} porphyrin (Pt-8Cn-TPP, n-alkyl = (CH2)(n), n = 4, 6, and 8) are presented. The protonated platinum porphyrins ([Pt-8Cn-TPPH8](8+)) were assembled with mesoporous silica MCM-48 resulting in the assembly materials [Pt-8Cn-TPPH8](8+)/MCM-48. The luminescence of [Pt-8Cn-TPPH8](8+)/MCM-48 can be extremely quenched by molecular oxygen with very high sensitivity (I-0/ I-100 > 5000) and rapid response time (0.04 s) suggesting that the [Pt-8C n-TPPH8](8+)/MCM-48 system can be employed to develop high performance oxygen sensors. Among this assembly system, [Pt-8C8-TPPH8](8+)/ MCM-48 exhibits the highest sensitivity. Even if the concentration of oxygen is 0.1%, the luminescence intensity of [Pt-8C8-TPPH8](8+)/ MCM-48 can be quenched by 86%.
