Synthesis, crystal structure and spectroscopic study of para substituted 2-hydroxy-3-methoxybenzalideneanilines

A New Chiral Schiff Base with Ferroelectric Property

“…110.6 (6) F(4)-C(11)-C(10) 115.0 (6) existing in the UV range are consistent with structural analysis with the existence of a big conjugated system. Fluorescence is a luminescence that occurs when a molecule or quantum dot relaxes to its ground state after being electronically excited.…”

“…4 So far, a great deal of work has been performed in the synthesis and characterization of Schiff base ligands, but there have been only few reports with regard to the derivatives of the Schiff base, which are produced with the ferroelectric property. 5,6 Ferroelectric materials in particular are of great interest, because they can be rapidly switched between different states by applying an external electric field. Furthermore, they display good memory capacity in the absence of an external field due to their hysteresis-loop behavior.…”

Synthesis and Characterization of New 3‐(3‐Hydroxyphenyl)‐4‐ alkyl‐3,4‐dihydrobenzo[e][1,3]oxazepine‐1,5‐dione Compounds

“…The absorption bands for υ CH 3 s and υ CH 2 as appear in the range of 2849-2870 and 2782-2858 cm -1 respectively. 22,26 The band observed in the range of 1404-1469 cm -1 is ascribed to the stretching of υ C-H 27 and a very weak band at 2760-2698 cm -1 is assigned to υ C-H .…”

3-Hydroxy-4-{[(4-bromophenyl)imino]methyl}phenyl Octadecanoate

“…

Abstract:A new Schiff base ester, 3-hydroxy-4-{ [(4-bromophenyl) Schiff bases have attracted overwhelming attentions from many researchers owing to their importance in exhibiting thermochromism and photochromism [1][2][3][4]. The presence of a long alkyl chain at the para position of the aldehyde or aniline fragment of N-benzylideneanilines has been regarded as one of the important elements which favours the existence of liquid crystal phases [5][6][7].
