摘　　要：A series of platinum meso-tetrakis [3-methoxy-4-(N-carbazyl)n-alkyloxyphenyl]porphyrin (Pt-4Cn-TPP, n = 4, 6 and 8) are synthesized. Pt-4C4-TPP, Pt-4C6-TPP and Pt-4C8-TPP exhibit similar luminescent properties in solution and solid state. Three protonated platinum (II) porphyrins are assembled with mesoporous silica MCM-48, respec- tively, resulting in assembly materials Pt-4Cn-TPP4+/ MCM-48 (n = 4, 6 and 8). The luminescent intensity of Pt-4Cn-TPP4+/MCM-48 can be extremely quenched by molecular oxygen with high sensitivity (I0/I100 > 9). The Stern-Volmer plots of these assembly materials display considerable linearity within a wide range of oxygen concentration (0 to 100%). The re- sponse time is all ≤ 1 s and recovery time ≤ 22 s for these assembly materials.A series of platinum meso-tetrakis [3-methoxy-4-（N-carbazyl）n-alkyloxyphenyl]porphyrin （Pt-4Cn-TPP, n = 4, 6 and 8） are synthesized.
