Abstract

The aim of this thesis is centred on the resynthesis, characterization, and application of a chemical derivative of naphthalene diimide. N,N’-bis(4-sulfophenyl)-1,4,5,8- naphthalene diimide (SNDI), was extensively studied and evaluated for its potential application as a chemosensor in a polar aprotic solvent. The selectivity and sensitivity of SNDI toward a range of metal cations, including Co²⁺, Ag⁺, Cu²⁺, Fe³⁺, Hg²⁺, Ca²⁺, Mg²⁺, Cd²⁺, Pb²⁺ and Zn²⁺, were investigated. FT-IR spectroscopy analysis was done to corroborate the structure of the synthesized product. This derivative of naphthalene diimide N,N’-bis(4-sulfophenyl)-1,4,5,8-naphthalene diimide (SNDI) was found to be a good candidate for chemosensor for iron and mercury ions in a polar aprotic solvent. Keywords: naphthalene diimide, water soluble, chemosensor, polar aprotic solvent.

Bu tezin amacı, bir naftalin diimid türevinin yeniden sentezi, karakterizasyonu ve uygulaması üzerine odaklanmaktadır. N,N’-bis(4-sülfofenil)-1,4,5,8-naftalin diimid (SNDI), polar aprotik bir çözücü içinde kemosensör olarak potansiyel uygulaması açısından kapsamlı bir şekilde incelenmiş ve değerlendirilmiştir. SNDI'nin Co²⁺, Ag⁺, Cu²⁺, Fe³⁺, Hg²⁺, Ca²⁺, Mg²⁺, Cd²⁺, Pb²⁺ ve Zn²⁺ gibi bir dizi metal katyonuna karşı seçiciliği ve duyarlılığı araştırılmıştır. Sentezlenen ürünün yapısını doğrulamak için FT-IR spektroskopi analizi yapılmıştır. Bu naftalin diimid türevi olan N,N'-bis(4- sülfofenil)-1,4,5,8-naftalin diimid (SNDI), polar aprotik bir çözücüde demir ve civa iyonları için iyi bir kemosensör adayı olarak bulunmuştur. Anahtar Kelimeler: naftalin diimid, polar aprotik çözücü, suda çözülen, kemosensör
