The title salt, [K(C(12)H(24)O(6))][Fe(C(8)H(12))(C(10)H(8))], is the only known naphthalene complex containing iron in a formally negative oxidation state. Each (naphthalene)(1,5-cod)ferrate(-I) anion is in contact with one (18-crown-6)potassium cation via K⋯C contacts to the outer four carbon atoms of the naphthalene ligand (cod = 1,5-cyclo-octa-diene, 18-crown-6 = 1,4,7,10,13,16-hexa-oxacycl...

The asymmetric unit of the title compound, C(18)H(11)NO(2)S, contains two crystallographically independent mol-ecules. In one mol-ecule, the oxazole and thio-phene rings are oriented at dihedral angles of 17.40 (9) and 18.18 (7)° with respect to the naphthalene ring system, while the oxazole and thio-phene rings are oriented to each other at a dihedral angle of 0.86 (9)°. In the other mol-ecule...

In this work, we explore the potential use of the Pseudomonas putida KT2440 strain for bioremediation of naphthalene-polluted soils. Pseudomonas putida strain KT2440 thrives in naphthalene-saturated medium, establishing a complex response that activates genes coding for extrusion pumps and cellular damage repair enzymes, as well as genes involved in the oxidative stress response. The transfer o...

Replacement of phenyl ring(s) in tetraphenylethene by naphthalene ring(s) generates a series of new luminogens with aggregation-induced emission (AIE) characteristics, demonstrating that bulky naphthalene rings can serve as a rotor to construct AIE luminogens.

A new host molecule, having two azacrown derivatives bridged by luminescent naphthalene diimide functionality, is found to form a [3]pseudorotaxane derivative with imidazolim ion-based guest molecules in non-polar solvents through hydrogen-bonded adduct formation. Depending upon the length of the covalent linker that links the imidazolium ion and the luminescent naphthalene fragment in the gues...

The title compound, C17H14Cl4N5OP3, is a spiro-phosphazene derivative with bulky naphthalene and pyridine rings. The phosphazene and the six-membered N/O rings are in flattened-boat and twisted-boat conformations, respectively. The naphthalene ring system and the pyridine ring are oriented at a dihedral angle of 18.06 (8)°. In the crystal, weak π-π stacking between the pyridine rings and betwee...

Density function theory with B3LYP parameterization and 6-31++G(d,p) basis set has been used to investigate the structure and stability of many mono-substituted naphthalene molecules. The Molecular Electrostatic Surface Potential (MESP) topography for all the mono-substituted naphthalene molecules was obtained. It is shown that the nature of the substituent and its orientation in the molecule p...

The title compound, C(17)H(12)N(2), comprises a norbornane unit having a dicyanona-phthalene ring fused on one side. Both cyano groups are twisted slightly out of the plane of the naphthalene ring system [C-C-C-C torsion angle = 1.9 (2)°]. In the crystal, inversion-related mol-ecules are linked by pairs of weak C-H⋯N hydrogen bonds, forming dimers.

In the title compound, C22H16N2O6, the naphthalene ring systems form a dihedral angle of 65.2 (1)°. Two O atoms of one of the nitro groups are disordered over two sets of sites with occupancy factors of 0.586 (15) and 0.414 (15). Weak C-H⋯O inter-molecular inter-actions are present, forming a ladder like structure along the a axis.

AIMS To estimate exposures to benzene and naphthalene among military personnel working with jet fuel (JP-8) and to determine whether naphthalene might serve as a surrogate for JP-8 in studies of health effects. METHODS Benzene and naphthalene were measured in air and breath of 326 personnel in the US Air Force, who had been assigned a priori into low, moderate, and high exposure categories fo...
