Cu₄O₄ Kübik Formdaki Bakır (II) Kompleksinin Yapısal ve Fotolüminesans Özelliklerinin İncelenmesi

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.
