The fluorescence response functions of oxygen-free benzene solutions containing 3 x 10 3 >1 anthracene and concentrations of up to 1.2 x M perylene were observed using the phase and modulation fluorometer. The response functions of the directly excited anthracene and perylene fluorescence are simple exponential decay functions, while that of the perylene fluorescence, indirectly excited by ener...

In the title compound, C(25)H(20)N(2)O, the pyrazoline ring is nearly planar [maximum atomic deviation = 0.0254 (17) Å]; but the anthracene ring system is distorted from a coplanar structure [maximum atomic deviation = 0.181 (3) Å], the dihedral angle between the outer benzene rings being 10.68 (13)°. The pyrazoline ring is almost perpendicular to the mean plane of the anthracene ring system [d...

In the title compound, C21H16O, the dihedral angle between the anthracene ring system and the benzene ring is 74.3 (5)°. The anthracene ring system is essentially planar (r.m.s. deviation = 0.0257 Å) and the meth-oxy group lies in the plane of the benzene ring [C1-O1-C2-C7 torsion angle = 0.5 (2)°]. The crystal structure features π-π [centroid-centroid distance = 3.9487 (12) Å] and C-H⋯π inter-...

A novel anthracene-tagged oligonucleotide can discriminate between a fully-matched DNA target sequence and one with a single mismatching base-pair through a remarkable difference in fluorescence emission intensity upon duplex formation.

The cycloadducts of tethered naphthalene and anthracene derivatives undergo photochemical ring opening to an electronically excited product with adiabatic yields up to 90%.

In the title compound, C(19)H(17)NO(2), the piperidine ring adopts a chair conformation. The mean planes of the piperidine ring and the anthracene ring system are inclined at a dihedral angle of 38.7 (1)°. In the crystal, adjacent mol-ecules are linked through C-H⋯π and π-π [centroid-centroid distance = 3.782 (1) Å] inter-actions, forming a layer parallel to the bc plane.

The photo-reversible [4πs+4πs] cycloaddition reaction of pendant anthracene moieties represents a convenient strategy to impart wavelength dependent properties into hydrogenated carboxylated nitrile butadiene rubber (HXNBR) networks. The present article provides the 1H NMR data on the reaction kinetics of the side chain functionalization of HXNBR. 2-(Anthracene-9-yl)oxirane with reactive epoxy ...

The synthesis of various 1,8-diaza-4,5-dialkoxy-2,7-anthracene dicarboxylic acid derivatives and their incorporation into cyclic and helically folded aromatic oligoamides are reported. The ability of the diaza-anthracene monomers to undergo photoaddition or head-to-tail photodimerization was investigated in the solid state and in solution. Quantitative conversion of a monomer diester to the cor...

Mixing soil or adding earthworms (Eisenia fetida (Savigny, 1826)) accelerated the removal of anthracene, a polycyclic aromatic hydrocarbon, from a pasture and an arable soil, while a non-ionic surfactant (Surfynol® 485) inhibited the removal of the contaminant compared to the untreated soil. It was unclear if the treatments affected the soil bacterial community and consequently the removal of a...
