“…Salih İlhan et al have reported the formation of Schiff base by the condensation of monomer o-HOB with 2,6-diaminopyridine. 34 Similar reactants were used for the synthesis of polymer PoHOBP, the melting/decomposition point of the polymer (PoHOBP) was above 360 °C while the reported Schiff base decomposed at 280 °C, the mass spectrum of the polymer (PoHOBP) obtained through E.I mass spectroscopy did not show the mass corresponding to Schiff base, the polymer (PoHOBP) had higher mass than the reported Schiff base which supported the formation of the polymer (PoHOBP).…”

Five new azomethine polymers having aliphatic-aromatic moieties were synthesized by polycondensation reaction of dialdehydes and diamines. The dialdehyde monomers differ only in the orientation of the aromatic ring (ortho or para) and were synthesized by condensation reaction between aromatic aldehyde and 1,6-dibromohexane. The molecular mass of the monomers was recorded through E.I mass spectrum. The polymers structures were confirmed by elemental microanalysis, FT-IR, 1 HNMR and UV-Vis Spectroscopy. The morphology of monomers and polymers was evaluated by scanning electron microscopy (SEM). All the polymers were soluble in DMSO (on heating) and somewhat in other solvents. Thermal stability of polymers was analyzed by thermogravimetry (TG) and differential thermal analysis (DTA), all the polymers showed good thermal stability higher than their corresponding monomers. The TG of polymers indicated maximum rate of weight loss (T max) within 412-708 °C. Fluorescence emission spectra of polymers were recorded and the results indicated that all the polymers were photo-responsive and indicated 1 to 4 emission bands with maximum within 349-606 nm. The limit of detection of polymers was within 0.625-1.25 µg/ml. The polymers were also examined for their antimicrobial activities against bacteria and fungi.

“…Many synthetic methods for the preparation of Schiff base macrocyclic compounds use transition metal ions as templating agents [16][17][18][19][20][21]. However, this method yields stable macrocyclic complexes, thus making the preparation of a metal free ligand difficult [16][17][18][19][20][21].…”

UDC 548.737The reaction of 1,4-diaminobutane with 2,2′-diformyl-6,6′-dimethoxy-diphenoxypropane in a mixed solvent of methanol and chloroform results in a new 17-membered macrocyclic Schiff base compound MeO-sal-pn-pn. The title compound is characterized by the elemental analysis (CHN), FT-IR, 1 H NMR spectroscopy, and powder X-ray diffraction. The crystal data are: M r = 396.5, orthorhombic, P2 1 2 1 2 1 , with unit cell parameters: a = 4.71769(3) Å, b = 19.1524(2) Å, c = 22.9418(2) Å, V = 2072.90(3) Å 3 , and Z = 4.The macrocyclic Schiff base compounds and their transition metal complexes play a key role in coordination chemistry [1][2][3][4][5]. They are extensively studied for their capacity to bind and transport metal ions, for the possibility to act as models for metalloproteins [6,7]. and for their role in host-guest and supramolecular chemistry [8][9][10]. Macrocycles containing imine groups can form mono-, di-, and polynuclear transition metal complexes with various applications [11][12][13][14]. Among them a wide Schiff base macrocycles based on 2,6-diacetylpyridine and 2,6-diformylpyridine as building blocks evolved from the early studies [15].Many synthetic methods for the preparation of Schiff base macrocyclic compounds use transition metal ions as templating agents [16][17][18][19][20][21].

Therefore, during the last decade, considerable effort has been made to develop metal free methods for the preparation of Schiff base macrocyclic compounds [15,[22][23][24]. Recently, many compounds in this field have been rapidly developed and studied [25]. Herein, we report the synthesis, characterization, and crystal structure of a 17-membered [1+1] macrocyclic Schiff base compound MeO-sal-pn-bn obtained by the condensation of 1,4-diaminobutane with 2,2′-diformyl-6,6′-dimethoxy-diphenoxypropane in a mixed solvent of methanol and chloroform (1:1 v/v) (Scheme 1).
