| 中文摘要 | we synthesized a novel histidine salt of 12-silicotungstate supramolecular compound ((hish(2))(2) siw(12)o(40)center dot 6h(2)o) by a solution method. its composition, thermostability, and structure were characterized by elemental analysis, thermal gravimetric and differential thermal analysis (tg-dta), and single crystal x-ray diffraction, respectively. the experimental results show that the supramolecular compound has a composition of c(12)h(34)n(6)o(50)siw(12) and it is stable under 135 degrees c in air. it belongs to a monoclinic system (space group c2/c) with a=2.44005(18) nm, b=1.29788(10) nm, c=1.86898(14) nm, beta=124.0380(10)degrees, v=4.9048(6) nm(3), z=4, and d(c)=4.465 g . cm(-3). the final statistics based on f(2) are goodness-of-fit (gof) = 1.268, r(1)=0.0344 and wr(2)=0.0851 for (i>2 sigma(i)). x-ray diffraction analysis further reveals that this supramolecular compound mainly consists of polyoxometalate anions [siw(12)o(40)](4-), protonated histidine cations [hish(2)](2+) and lattice water. a three-dimensional (3d) network is formed through hydrogen bonding. the resulting sample shows photochromism under uv irradiation. we propose a possible photochromic mechanism by an analysis of the chromic sample's electron spin resonance (esr) spectrum. |
