Abstract
A novel luminescent platinum(II) complex platinum 5,10,15,20-tetra{4-[(N-carbazyl)butyloxyphenyl]}porphyrin (PtTCBPyP) has been synthesized and characterized by 1H NMR, elemental analysis, IR and UV–vis. The platinum porphyrin is assembled with mesoporous silica SBA-15 and MCM-41 resulting in the assembly materials PtTCBPyP/SBA-15 and PtTCBPyP/MCM-41. The luminescence of platinum porphyrin complex/silicate assemble materials can be quenched by molecular oxygen with very high response (I0/I100 > 8700 for PtTCBPyP/SBA-15(20 mg/g) and I0/I100 > 3800 for PtTCBPyP/MCM-41(20 mg/g)), indicating that platinum porphyrin complex/silicate systems can be employed to develop high performance oxygen sensors. Among this assembly system, PtTCBPyP/SBA-15(20 mg/g) exhibits the highest response of platinum porphyrin complex/silica.
