In the title compound, C(17)H(14)O(6), the dihedral angle between the two anhydride rings is 76.01 (8)°while the dihedral angles between the benzene and anhydride rings are 42.60 (7) and 68.94 (7)°. The cyclo-hexene ring of the tetra-hydro-naphthalene unit exhibits an envelope conformation.

In the title compound, C(20)H(16)O(5), the dihedral angle between the naphthalene ring system and the benzene ring is 67.43 (5)°. The bridging carbonyl C-C(=O)-C plane makes dihedral angles of 82.64 (6) and 41.79 (7)°, respectively, with the naphthalene ring system and the benzene ring. The dihedral angle between the carb-oxy O-C(=O)-C plane and the benzene ring is 36.38 (7)° and that between t...

In the title compound, C20H13ClN2O, the chloro-benzene ring is almost perpendicular to the mean plane of the naphthalene ring system, making a dihedral angle of 81.26 (8)°. The 4H-pyran ring fused with the naphthalene ring system has a flattened boat conformation. In the crystal, N-H⋯N hydrogen bonds generate chains along the b-axis direction. Further N-H⋯N hydrogen bonds link these chains into...

Naphthalene diimide amphiphiles functionalized with the dipicolylethylenediamine motif self-assemble with tunable chirality upon molecular recognition with various adenosine phosphates and competitive guest binding leads to the dynamic helix reversal of these assemblies.

The aim of this work was to correlate the textural and chemical features of carbonaceous adsorbents with the adsorption capacity of naphthalene from aqueous phase, at the concentration in which this compound is usually found in wastewater from coke ovens. The study reveals that the adsorption capacity in different carbon materials depends not only on the textural characteristics of the material...

In the title compound, C(30)H(31)NO(2), the cyclo-hexa-none ring in the naphthalene fused-ring system adopts a half-chair conformation, presumably due to conjugation of the benzene ring. The naphthalene ring system makes dihedral angles of 86.63 (7), 65.15 (8) and 63.18 (8)° with respect to the two methyl-benzene planes and the 1,2-oxazole ring system. Inter-molecular C-H⋯O and C-H⋯N hydrogen b...

We have developed an active-space decomposition strategy for molecular dimers that allows for the efficient computation of the dimer's complete-active-space wavefunction while only constructing the monomers' active-space wavefunctions. Dimer states are formed from linear combinations of direct products of localized orthogonal monomer states and Hamiltonian matrix elements are computed directly ...

In the title compound, C(19)H(15)NO(5), the dihedral angle between the naphthalene ring system and the benzene ring is 61.97 (5)°. The dihedral between the naphthalene ring system and the bridging carbonyl C-C(=O)-C plane is 54.68 (6)°, far larger than that [12.54 (7)°] between the phenyl group and the bridging carbonyl group. The nitro group and the phenyl ring are almost coplanar [O-N-C-C tor...
