In the title compound, C36H28O4, the two 2-naphthoyl groups at the 1- and 8-positions of the central 2,7-dieth-oxy-naphthalene ring system are aligned almost anti-parallel and make a dihedral angle of 48.35 (5)°. The dihedral angles between the central 2,7-dieth-oxy-naphthalene ring system and the terminal naphthalene ring systems are 77.64 (4) and 73.73 (4)°. In the crystal, mol-ecules are lin...

Structural modification of unidirectional light-driven rotary molecular motors in which the naphthalene moieties are exchanged for substituted phenyl moieties are reported. This redesign provides an additional tool to control the speed of the motors, and should enable the design and synthesis of more complex systems.

The optoelectronic and excitonic properties in a series of linear acenes (naphthalene up to heptacene) are investigated using range-separated methods within time-dependent density functional theory (TDDFT). In these rather simple systems, it is well-known that TDDFT methods using conventional hybrid functionals surprisingly fail in describing the low-lying L(a) and L(b) valence states, resultin...

The title compound, C(19)H(21)NOS, is an inter-mediate for the synthesis of duloxetine hydro-chloride. In the mol-ecular structure, the thio-phene and naphthalene ring systems make a dihedral angle of 87.5°. All bond lengths and angles involving heteroatoms are as expected. In the crystal structure, no classical hydrogen bonds are found.

In the field of polyfunctional Lewis acids [1] the preorganisation of the Lewis acidic sites can be achieved employing rigid backbones. Ortho-substituted benzenes [2], peri-substituted naphthalene [3 – 6] and 1,8substituted anthracene [7, 8] offer promising applications as such backbones in the field of host-guest chemistry [9]. Furthermore, these frameworks can induce unusual interactions betw...

Photolysis into the longest wavelength absorption band of 2-tert-butyl-2,3-diazabicyclo[2.2.2]oct-3-yl hydrazine (Hy) substituted naphthalenes causes aryl group reduction electron transfer to give (+)Hy-Ar(-). Electrooptical absorption measurements characterize the charge separation properties from these bands. Emission studies demonstrate that the separation between absorption and emission max...

Abstract We report the synthesis of a [20]cyclophenacene‐type cyclophenylene‐naphthylene (CPN) belt and enantioselective chiral‐type CPN belts (up to >99 % ee ) by cationic rhodium(I)‐catalyzed intramolecular [2+2+2] cycloaddition naphthalene‐embedded cyclic polyynes. The depth‐expanded was also attempted, but final unsuccessful. Theoretical calculations clarified that reactivity depends on ...
