“…In most cases the binding with alkali metal cations was studied, where both the spectroscopic and electrochemical properties of the complex were perturbed by cation binding. 131,135,137,164,165 Duan, Bai, and coworkers reported [Ru(L 13 )(bpy) 2 ] 2+ (where L 13 is 4,5-diazafluoren-9-one-2,4-dinitrophenylhydrazone) as a selective chromo-and fluorogenic dual responding fluoride sensor. 166 Not only does the presence of F − enhance the luminescence intensity but also triggers a dramatic color change from yellow to magenta.…”

This perspective review will examine the coordination chemistry and applications of metal complexes of 4,5-diazafluorene derivatives. The versatile derivatives of 4,5-diazafluorene can serve multiple roles, and display a number of coordination modes. The ambidentate derivatives with multiple coordination sites can allow for the syntheses of coordination polymers, multimetallic, and macrocyclic complexes. In addition, certain 4,5-diazafluorene derivatives can serve as spectator ligands to support reactivity at the metal centre, or as reactive actor ligands engaging in atypical reactivity patterns. The applications of metal complexes of 4,5-diazafluorene derivatives in catalysis, photochemistry and photophysics, as well as in bioinorganic chemistry are also surveyed.

Bu çalışmada 4′,5′-bis(bromometil)benzo-15-crown-5 ile 2-iyodo-3-hidroksipiridin etkileştirilerek, yeni, çift kollu taç eter ligandı (L) sentezlenmiştir. Sentezlenen ligand (L), Na+ ve K+ kompleksi elde etmek üzere sodyum pikrat ve potasyum pikrat ile tepkimeye sokulmuştur. Böylelikle, benzo-15-crown-5’in halka boşluğuna uygun olan Na+ ile 1:1 (filling) kompleksi (NaL) ve halka boşluğundan daha büyük olan K+ ile 1:2 (sandviç) kompleksi (KL2) elde edilmiştir. Ayrıca bileşik L’nin gümüş nitrat ile reaksiyonu sonucunda geçiş metal kompleksi (AgL) sentezlenmiştir. Elde edilen ligand ve komplekslerin yapısı, spektroskopik yöntemler (FTIR, HRMS, 1H-NMR, 13C-NMR) kullanılarak aydınlatılmıştır. Son olarak, sentezlenen ligand ve komplekslerin termal özellikleri TGA - DTA yöntemleri kullanılarak incelenmiş ve bileşik yapıları ile uyumlu sonuçlar elde edilmiştir.

“…35 Furthermore, these compounds can form various complexes by coordination to metal ions such as Fe 3+ , 36 Cu 2+ , 37,38 Cd 2+ , 39 Eu 3+ , 40 and Ru 2+ . 41,42 The 4,5-diaza-uorene has been chosen as an ideal structure of a uorescent chemosensor due to its large p-system and bidentate coordination ability with various metal ions. Some Ru(II) polypyridyl complexes containing 4,5-diazauorene units has been employed as uorescent probes for metal ions.…”
