Effects of pore surface silylation and cesium doping on the siloxane bonding structure of mesoporous silica (MPS) film were analyzed using infrared spectroscopy. MPS film was derived by sol–gel method and self-assembling technology of non-ionic surfactant template. Cesium (Cs) catalyst was doped to the precursor solution with the amounts of 0, 5, and 15 wt-ppm. Vapor phase silylation was performed...
Sub-micrometer long butadiyne-linked porphyrin wires were synthesized by oxidative coupling of diethynylporphyrin. The porphyrin wires were analyzed by analytical gel permeation chromatography, absorption spectroscopy and matrix-assisted laser desorption/ionization time of flight mass spectroscopy. Observations of the wire were performed by atomic force microscopy. Self-assembled structures of the...
