Abstract:

 

New thermally stable water soluble azo dye and azo-Schiff base polymer dyes were synthesized via conden- sation reaction of 4-methyl pyridine and poly- 4,4’-diamino biphenyl-2,2’-disulfonic acid with substituted azo-coupled 2-hydroxy-5-  4-nitrophenyl diazenyl  benzaldehyde. For the structural analyses of synthesized substances FT-IR and NMR analysis, florescence and UV-Vis measurements for optical properties and the thermal behavior  TG-DTA  of the prepared dyes have been determined using thermogravimetric technique. Azomethine dyes  AZOBMS and AZOBMSP  have relatively higher thermal durability in comparison to azo dye  AZOBM . The solvatochromic studies of the prepared dyes in DMSO, DMF, CH3CN and THF. In addition, spect- rophotometric and spectrofluorometric studies showed that these dyes were good absorbent and fluorescent. The effect of various organic solvents with different polarities on the UV-Vis spectra and fluorescence analyses of the dyes has been also studied.

 

Metil piridin ve poli 4,4’-diamino bifenil-2,2’-disülfonik asit ile 2-hidroksi-5-  4-nitrofenil4 diazenil  benzaldehit bileşiği ile yeni ısıl kararlı suda çözünebilen azo boyaları ve azo-Schiff baz polimeri boyaları sentezlendi. Sentezlenen maddelerin yapısal analizleri FT-IR ve NMR, optik özellikleri için floresans ve UVVis ölçümleri, termogravimetri tekniği kullanılarak ısıl davranışları  TG-DTA  ölçüldü. Azometin boyaların  AZOBMS ve AZOBMSP  solvatokromik çalışmaları DMSO, DMF, CH3CN ve THF de yapıldı. Ayrıca farklı organik çözücülerde spektrofotometrik ve spektrofloremetrik çalışmaları sonucunda iyi absorban ve floresan özellik gösterdiği gözlendi.
