The synthesis and spectroscopic studies of azlactone containing thiophenyl

In this study, derivatives of 1,3-oxazole-5(4H) contained thienyl groups from five memberedheterocyclic systems, known as unsaturated azlactone class were synthesized by the knownmethods. The structures of new synthesized thienyl derivatives were characterized by FT-IR,1H NMR spectroscopic methods. Photophysical characteristics of the derivatives in solventsof acetonitrile (ACN), tetrahydrofuran (THF), dichloromethane (DCM) and polyvinylchloride(PVC) polymer matrix which contain plasticizer was determined with UV-vis absorption andemission spectroscopy. PVC thin film matrices of oxazole-5-one derivatives which containsthienyl groups was prepared and then, the answers against to Fe(III) , Co(II) , Ni(II) ,Zn(II)and Cu(II) cations having biological importance were investigated.Also using electropolymerization techniques, the electropolymerizations of thienyl groups ofthese derivatives were tried. All the synthesized derivatives are listed below.PTO-I 2-phenyl-4-(2-thienylmethylene)-1,3-oxazol-5(4H)-onePTO-II 2-(4-nitrophenyl)-4-(2-thienylmethylene)-1,3-oxazol-5(4H)-onePTO-III 2-(4-methylphenyl)-4-(2-thienylmethylene)-1,3-oxazol-5(4H)-onePTO-IV 2-(2-thienyl)-4-(2-thienylmethylene)-1,3-oxazol-5(4H)-onePTO-V 2-(2-thienyl)-4-(3-thienylmethylene)-1,3-oxazol-5(4H)-onePTO-VI 2-(3-thienyl)-4-(2-thienylmethylene)-1,3-oxazol-5(4H)-onePTO-VII 2-(3-thienyl)-4-(3-thienylmethylene)-1,3-oxazol-5(4H)-one
