dc.description.abstract | In this study, α-TiP layered structure incorporating a heterometal center for organic ligand binding to enhance structural complexity and functionality were prepared. The protons of the α-TiP layer were replaced with zinc ions coordinated by 4-pyridinecarboxylic acid (PCA) and water to form a layer structure, TiZn(PO4)2(H2O)(PCA) (1). The tetrahedral zinc center with coordinated water in 1 is unprecedented in zincophosphate or zinc-MOF systems and is usually only found in metalloenzyme systems. The neutral zincotitanophosphate layers, tightly stacked through hydrogen bonds, showed velcro-like behavior on intercalating 4,4′-trimethylenedipyridine (TMDP) reversibly. It rendered a remarkable luminescence property to 1, emitting blue-to-white light under UV excitation. Surprisingly, the replacement of TMDP for PCA in the hydrothermal synthesis still resulted in 1, plus another structure, Ti4Zn2(H2TPB)(PO4)4(HPO4)4(H2PO4)2 (2) (TPB=1,2,4,5-tetra(4-pyridyl)benzene). Clearly, in situ C−C cracking and C−C coupling of TMDP simultaneously occurred to generate PCA and TPB and thereafter the oxidant, Zn(NO3)2, was quantitatively determined to isolate crystal 1 from 2. The structure of 2 also featured α-TiP layers with pedant Zn tetrahedra but formed a three-dimensional neutral framework through TPB. For the first time, α-TiP-derived structures and their properties have been elucidated, which help in understanding intriguing in situ ligand formation and intercalation-induced luminescence, to exploit potential photocatalysis in polymerization. | - |
