摘要：

Aluminophosphate-hosted methylene blue samples are obtained by addition of the dye to the reaction mixture for the hydrothermal synthesis of AlPO4-5, SAPO-5, SAPO-34, and FAPO-5. The colored crystalline products contain 10(-6)-10(-4) mol dye per gram molecular sieve, i.e., they exhibit an average loading ranging from 0.01 to 0.1 methylene blue molecules per unit cell. The analysis of the optical spectra indicates that dye monomers are encapsulated in the cages of SAPO-34 and that monomers as well as dimers are hosted simultaneously in the parallel, cylindrical unidimensional channels of AlPO4-5 and SAPO-5.
