Abstract:

The significant influence of F- on the structure-directing effect of ethylenediamine(en) and diethylenetriamine(deta) in the synthesis of open-framework aluminophosphates was investigated. For the system with ethylenediamine, in the absence of F-, layered aluminophosphate Al2P2O9·NH3(CH2)2NH3(UiO-13) was obtained from the initial mixture with n(Al2O3):n(P2O5):n(en):n(H2O)=1.0:1.5:18.0:147 under hydrothermal condition, while layered aluminophosphate AlF(HPO4)·NH2(CH2)2NH2(1) was obtained from the initial mixture with n(Al2O3):n(P2O5):n(en):n(HF):n(H2O)=1.0:1.5:18.0:3.0:147. The results suggested that the F- significantly affected the structure-directing effect of ethylenediamine. For the system with diethylenetriamine, a three-dimensional(3D) open-framework aluminophosphate Al4P5O20(H2O)2·C4N3H16(AlPO-CJ31) was synthesized from the initial mixture with n(Al2O3):n(P2O5):n(deta):n(H2O)=1.0:4.0:3.0:153 under hydrothermal condition, while a one-dimensional(1D) aluminophosphate Al2P4O10(OH)3F·C4N3H15(2) was crystallized from the similar initial mixture in the presence of F-[n(Al2O3):n(P2O5):n(deta):n(HF):n(H2O)=1.0:4.0:3.0:3.0:153]. The results indicated that the structure-directing effect of diethylenetriamine was significantly altered by F-. The structural properties of open-framework aluminophosphates UiO-13, 1, AlPO-CJ31 and 2 were analyzed in detail and the influence of F- on the structure-directing effect of ethylenediamine and diethylenetriamine was discussed.
