초록

p-XBP4 (N,N'-p-phenylenedimethylenbis(pyridin-4-one)), Cs3[W(CN)8]와 Tb(NO3)3·6H2O를 사용하여 2차원의 이중 상호 침투 구조를 갖는 새로운 Tb-MOF인 [Tb(p-XBP4)2.5(H2O)2]·W(CN)8를 합성하였다. 단결정 X선 회절 분석법으로 얻어진 구조 정보를 통해 Tb-MOF는 이중 상호 침투된 독특한 2차원 구조임을 확인하였다. 또한, 적외선 분광 분석법, 단결정 및 분말 X-선 회절 분석법을 활용하여 추가적인 특성 분석을 수행하였다. Tb-MOF가 갖는 자성 특성과 분자 자석으로서의 거동 가능성을 조사하기 위해, 직류 자화율 및 교류 자화율을 측정하고 이를 분석하였다.

A new two-fold interpenetrating two-dimensional (2D) Tb(III) metal-organic framework (MOF), [Tb(p-XBP4)2.5(H2O)2]·W(CN)8 (1), was prepared using a p-XBP4 (N,N'-p-phenylenedimethylenbis(pyridin-4-one)), Cs3[W(CN)8], and Tb(NO3)3·6H2O. The single crystal X-ray diffraction indicated that Tb-MOF exhibits a unique two-fold interpenetrating 2-D framework. It was also characterized through Fourier transform infrared spectroscopy (FTIR), and single and powder X-ray diffraction. To probe the molecular magnetic behavior, the magnetic properties of Tb-MOF were investigated by direct-current (DC) and alternating-current (AC) magnetic susceptibilities measurements and discussed.
