Son zamanlarda, kolorimetrik ve floresan sensörler, sulu ortamdaki ağır ve geçiş metal iyonlarının duyarlı ve seçici olarak tayin çalışmalarında düşük maliyet, kolay kullanım, yüksek performans, karmaşık olmayışı, test kiti olarak hazırlanma gibi avantajlar sağladıkları için önemli derecede ilgi çekmiştir. Bu çalışmada, kumarin temelli yeni bir kemosensör sentezlenmiş ve elementel analiz, FT-IR, Tandem kütle, 1H NMR ve 13C NMR spektroskopileri kullanılarak karakterize edilmiştir. Daha sonra, sensör C1’in seçicilik ve duyarlılık özelliği, biyolojik ve çevresel açıdan öneme sahip bazı metal iyonlarına karşı DMSO-H2O (v/v, 2:1) ortamında araştırılmıştır. UV-vis absorpsiyon ve floresan deneylerinden elde edilen sonuçlar, kemosensör C1’in sadece demir (II) iyonlarına yönelik seçicilik ve duyarlılık gösterdiğini ortaya çıkarmıştır.
