“…In (a), the bands at 1780 and 1857 cm 21 were characteristic to PSMAH, which showed the asymmetrical and symmetrical carbonyl absorption of anhydride groups, respectively. The IR bands at 1600, 1492, and 1452 cm 21 were stretching of C¼ ¼C of phenyl groups on the backbone. The 1217 cm 21 band was attributed to the CÀ ÀOÀ ÀC stretch of maleic anhydride units, having as five-membered cycloanhydride for t CÀ ÀOÀ ÀC band at 1310-1210 cm 21 .…”

“…The peaks due to the unreacted anhydride groups clearly disappeared at 1780 and 1857 cm 21 . It is known in acetic acid that carboxylic acids often exist as dimmers because of strong hydrogen bonds in liquid or solid state, and not a very dilute solution in nonpolar solvents.…”

Supercritical CO 2 (ScCO 2 ) has been used to prepare molecularly imprinted polymers of poly(styreneco-maleic acid) (PSMA) for targeted uracil (URA). The condition of ScCO 2 was on 16 MPa between 35 and 508C. The resultant imprinted membranes prepared at 35 and 508C bound URA with 9.2 6 0.10 and 12.6 6 0.06 lmol g 21 , respectively. Competitive binding studies were undertaken in binary substrate solution containing each of URA/ DMURA, URA/Thymine, and URA/Cytosine with 2 lM. The URA imprinted membrane showed high separation factor (a) with 17 for both URA/DMURA and URA/Thymine and for URA/Cytosine, a 5 13. Results strongly suggested that the URA imprinted membrane had effective selectivity hydrogen bonding to separately bind in the binary components to the template. Effect of organic solvents on the URA imprinting in ScCO 2 was also studied, in addition to comparison of properties with those obtained in both ScCO 2 and water. Evidence presented that ScCO 2 medium was effective to prepare the URA imprinted membrane. We discussed that ScCO 2 fluid was efficient to fix the shape of URA template into the PSMA membrane through hydrogen bonding.

The (arylazo-6-aminouracil)nickel(II) derivatives [Ni II (DMA 3 U) 2 ] [HDMA 3 U = 1,3-dimethyl-5-(arylazo)-6-aminouracil; arylazo = phenylazo (1), p-Me-phenylazo (2), p-Cl-phenylazo (3)] have been synthesized and isolated in crystalline form. Single-crystal X-ray diffraction study of [Ni(1) 2 ] reveals that, in the complex, the metal center has a square-planar environment. The intramolecular N-H/π and C-H/π interactions hold in the solid state as well as in poor hydrogen-bond acceptor (HBA) solvents, but are disrupted in good HBA solvents.Crystal-structure analysis further shows that the NH groups of [a]
