摘要
The modification of o-acetylsalicylic acid by 3-aminopropyl triethoxysilane (APS) was achieved and the assembly of their corresponding organic-inorganic molecular-based hybrid material with the two moieties bridged by covalent bonds was obtained. It is utilized to coordinate to terbium ions and further happened hydrolysis and polycondensation processes by chemical active triethoxysilyl groups. The photophysical properties show that the triplet energy of modified o-acetylsalicylic acid is efficiently responsible for the antenna effect and matches with the emissive energy level of metal ions. Consequently, the intramolecular energy transfer process completed within these molecular-based hybrids and strong green emission of Tb 3+ was achieved.
