In the title hydrate, C10H10O4· H2O, the six-membered aliphatic ring that is fused to the benzene ring has a sofa shape, with the hydroxy group in the 3-position (that represents the sofa back) of the aliphatic ring occupying a quasi-axial position. The hydroxy group of the aromatic ring is hydrogen-bond donor to the carbonyl O atom; other O - H⋯O hydrogen bonds link the organic molecules and the water molecules into a three-dimensional network.

Bio-nanocomposite films based on chitosan/polyvinylpyrrolidone (CS/PVP) and graphene oxide (GO) were processed using the casting/evaporation technique. It has been found that the three components of bio-nanocomposites can be easily mixed in controlled conditions enabling the formation of thick films with high quality, smooth surface and good flexibility. Structural and morphological characterizations showed that the GO sheets are well dispersed in the CS/PVP blend forming strong interfacial interactions that provide an enhanced load transfer between polymer chains and GO sheets thus improving their properties. It has been found that the water resistance of the CS/PVP blend is improved, and the hydrolytic degradation is limited by addition of 0.75 and 2 wt % GO. The modulus, strength, elongation and toughness of the bio-nanocomposites are together increased. Herein, the steps to form new bio-nanocomposite films have been described, taking the advantage of the combination of CS, PVP and GO to design the aforementioned bio-nanocomposite films, which allow to have extraordinary properties that would have promising applications as eventual packaging materials. © 2014 Wiley Periodicals, Inc.

The non-H atoms of the two independent mol-ecules in the asymmetric unit of the title compound, C8H8BrN3O, are planar (r.m.s. deviations = 0.015 and 0.019 Å). In the crystal, the mol-ecules are linked into a zigzag chain along the c axis by C - H⋯O hydrogen bonds.

In the mol-ecule of the title compound, C15H 12BrN3·H2O, the phenyl ring is coplanar with the imidazopyridine ring system [dihedral angle = 0.4 (1)°]. The water mol-ecule is disordered over two positions with occupancies of 0.58 (1) and 0.42 (1), and it is linked to the main mol-ecule via an O - H⋯N hydrogen bond.

In the title molecule, C17H12BrN3O, the imidazopyridine ring system is almost coplanar with the furan ring [dihedral angle = 2.0 (3)°]. The benzyl phenyl ring is oriented at dihedral angles of 85.2 (2) and 85.5 (1)°, respectively, with respect to the furan ring and the imidazopyridine ring system. In the crystal, molecules are linked into chains propagating along the b axis by C-H⋯N hydrogen bonds. Adjacent chains are linked via short Br⋯Br contacts [3.493 (1) Å].

In the title compound, C21H16N2O 3, the fused-ring system (r.m.s. deviation = 0.067 Å) is slightly buckled at the carbonyl C atom of the anthracenyl ring system [deviation = 0.177 (1) Å] that is closer to an allyl substituent. The two allyl units lie on the same side of the fused-ring plane but are oriented in opposite directions, with N-C-C-C torsion angles of 126.9 (2) and 116.7 (2)°. In the crystal, the molecules are linked into chains propagating along the b axis by C-H⋯O hydrogen bonds.

The seven-membered fused-ring in the title compound, C12H 12N2S2, adopts a boat conformation (with the two phenyl-ene C atoms representing the stern and the methine C atom the prow). This methine C atom and the tertiary N atom also belong to a five-membered ring, which has an envelope conformation. In the crystal structure, molecules are linked about a center of inversion by pairs of N-H⋯S hydrogen bonds.

The seven-membered ring in the title compound, C20H 19N3O3, adopts a boat conformation with the two phenyl-ene C atoms representing the stern and the methyl-ene C atom the prow. The dihedral angle between the best plane through the seven-membered ring (r.m.s deviation = 0.358 Å) and the phenyl substituent is 55.8 (1)°. The two rings at either ends of the ethyl chain are staggered [N - CH2 - CH2 - N torsion angle = 57.5 (4)°].
