Abstract

Polimerik bakır (II) komplekslerinin tasarımı ve sentezi, moleküler biyoloji, manyetizma ve fotolüminesans alanlarındaki potansiyel uygulamalarından dolayı büyük ilgi uyandırmaktadır. Bu çalışmada, fotolüminesans özellikler gösteren {Cu₄O₄} kübik formda, C₃₈H₄₀Cl₄Cu₄N₄O₁₀(1) kompleksi rapor edilmektedir. Kompleks 1, solvotermal reaksiyon ile sentezlendi ve element analizi, FT-IR,  katı UV-Vis spektroskopisi ve tek kristal X ışını kırınımı ile karakterize edildi. Kristal yapı çalışmaları, kompleks 1 in kristal yapısındaki dört çekirdekli birimdeki bakır(II) iyonlarının bozulmuş kare piramit geometriye sahip olduğunu gösterdi. Kompleks 1 ve ligandı H₂L’nin katı durumdaki fotolüminesans özellikleri ise görünür bölgede oda sıcaklığında incelendi. Kompleks 1 ve ligandı H₂L UV ışık ile 349 nm de uyarıldığı zaman, kompleks 1 görünür bölgede 452 nm’de şiddetli mor emisyon gösterirken, ligandı H₂L 504 nm’de yeşil emisyon göstermektedir. Bu umut verici fotolüminesans davranış, bu tip bileşikler için duyarlı moleküler cihazlar veya organik ışık yayan diyotlar (OLEDs) için olası uygulamalara kapı açmaktadır.
