Outline of Final Research Achievements

The photo-triggered molecular release from the organic-inorganic polymer hybrids is presented in this manuscript. Initially, the preparation of the auto-degradable polymer is explained with the photo-cleavable group at the end of the polymer main-chain. The silica-based dye-loaded hybrids containing these polymers were fabricated. It was found that by UV irradiation, the end capping was removed, and then the auto-degradation occurs through the polymer main-chain. Finally, the molecular release of the loaded dyes was accomplished in various media by the UV irradiation. In particular, it was shown that both of hydrophobic and hydrophilic dyes can be applied in this system.
