Three Schiff bases 1-(4-chlorophenyl)-N-(naphthalen-1-yl)methanimine (1), 1-(4-methoxy phenyl)-N-(naphthalen-1-yl)methanimine (2), and 1-(4-chlorophenyl)-N-(2,6-diisopropyl phenyl)methanimine (3) were synthesized characterized by elemental analysis, 1H 13C NMR, FT-IR UV-Visible spectroscopic techniques. The crystal structure of compound 3 was obtained it revealed that the crystallized in a mono...

In the title compound, C(17)H(13)NO, the azomethine double bond adopts an E conformation. The naphthyl ring system and the benzene ring form a dihedral angle of 8.09 (10)°. The near-planar conformation of the molecule is consolidated by an intra-molecular O-H⋯N hydrogen bond, which forms an S(6) ring. In the crystal, mol-ecules are arranged in a zigzag fashion parallel to the c axis.

A rational synthetic approach to substituted naphtho[1,8-gh]quinolines using intramolecular cyclization in the presence of potassium series (naphthalen-1-yl)isoquinolines is described. The photophysical properties obtained compounds were studied; particular, fluorescence emission was detected range 454 - 482 nm with a quantum yield up 54%. We also calculated HOMO-LUMO energies and optimized mol...
