摘要： A new series of organic-inorganic hybrid porous gadolinium phosphonate (GdP) materials have been synthesized using benzene-1,3,5-triphosphonic acid as a phosphonic acid linker through a simple hydrothermal technique. The particle size and morphology are well controlled through the selection of suitable reaction conditions. The obtained materials exhibit very high specific surface area and crystalline pore walls with a triclinic structure having unit cell parameters a = 7.76 (3) Å; b = 8.60 (6) Å; c = 14.09 (7) Å; α = 100.08 (4)°; β = 84.23 (6)°; γ = 116.29 (6)°. The obtained GdP materials are further used as a magnetic resonance imaging (MRI) contrast agent with r 1 and r 2 values of 2.6 and 4.7 s −1 mM −1 , respectively. Organic-inorganic hybrid porous gadolinium phosphonate materials are synthesized using benzene-1,3,5-triphosphonic acid as phosphonic acid linker. 出版日期： 2015-05-12 資源來源： Royal Society of Chemistry 識別號： EISSN: 2046-2069 識別號： DOI: 10.1039/c5ra02004b
