抄録
Tetrakis(4-carboxyphenyl)porphine (TCPP), which is well known as a photochemical hole burning (PHB) dye, was incorporated in amorphous silica materials (a-SiO2) by a sol-gel process with using tetramethoxysilane (TMOS) and aminopropyltriethoxysilane (APTES). With using APTES as precursor of silica gel, TCPP was cross-linked to a-SiO2 matrix through aminopropyl group of APTES. The cross-linkage of TCPP and APTES was confirmed by the FT-IR measurement. The TCPP incorporated in a-SiO2 matrices showed activity in PHB. In the TCPP cross-linked a-SiO2, properties of photochemical hole, such as hole width, quantum efficiency and irreversible broadening under cycle annealing experiment, were improved. A burnt hole at 3.6 K was observed after cycle annealing experiment up to 80 K in the TCPP cross-linked a- SiO2.
