| Abstract: | A series of platinum meso-tetrakis 3-methyoxy-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, respectively, 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 (I

(0 to 100%). The response time is all ⩽ 1 s and recovery time ⩽ 22 s for these assembly materials. |
