| 초록 | mesoporous MCM-41 materials were prepared in very short crystallization time (∼30 min) upon microwave irradiation in comparison with conventional hydrothermal heating. With both microwave irradiation and hydrothermal heating, the MCM-41 formation via supramolecular templating method has been monitored by fluorescence and electron spin resonance (ESR) spectroscopy. Pyrene as a fluorescence probe and 4-(N, N-dimethyl-N-hexadecyl)ammonium-2, 2, 6, 6-tetramethyl piperidinyloxy iodide (CAT16) as a spin probe were respectively dissolved into the micelle solutions to form the MCM-41 precursor gels. These probes allow to monitor the supramolecular interaction between the anionic silicate species and the cationic surfactant molecules during the MCM-41 formation. [Re(CO)3(bpy)Cl] and Re(CO)3(bpy)(py)]+ complex (bpy=2, 2’-bipyridine) are encapsulated into the microporous NaY zeolite and mesoporous AlMCM-41 as photosensitizer. Photoactivation of CO2 is confirmed in the these rhenium complexes encapsu lated into NaY and AlMCM-41 as supramolecular hosts under visible light using in-situ FT-IR, diffuse reflectance UV-visible, and phtoluminescence spectroscopy. |
