So many results that aren't mine?
References in many bibliographies are sometimes referred to as "Surname, I", so the citations of academics whose Surname and initials are the same may occasionally interfere. This problem is often the case with citation indexes all over the world.
How can I see only citations to my article?
After searching the name of your article, you can see the references to the article you selected as soon as you click on the details section.

Abstract:

Bu çalışmada, 3-aminopropiltrietoksisilan (APTES) ve N-(2-aminoetil)-3-aminopropiltrimetoksisilan (AEPTMS) kullanılarak iki farklı polihedral oligomerik silseskioksan (POSS) sentezlenmiştir. Elde edilen bu POSS bileşikleri, salisilaldehit ve 5-bromosalisilaldehit ile kondenzasyon tepkimesi sonucu POSS Schiff bazları sentezlenmiştir. POSS ve ligand özelliğindeki türevlerinin yapıları spektroskopik (Elementel analiz (C, H, N), 1H-NMR, 29Si NMR, FT-IR) yöntemlerle aydınlatılmıştır. Schiff Bazlarının Cu(II) ve Ni(II) metal kompleksleri sentezlenmiştir. İzole edilen POSS Schiff bazı metal komplekslerinin yapıları FT-IR, Magnetik duyarlılık terazisi ve ICP-OES ile aydınlatılmaya çalışılmıştır. Sonuçlar, metal iyonlarının Schiff bazlarına fenolik oksijen ve azometin azotu üzerinden bağlandığını göstermiştir.

Synthesis and Characterization Of Schiff Bases and Cu(ii) and Ni(ii) Complexes Of Polyhedral Oligomeric Silsesquioxane (poss) Compounds
2022
Author:  
Abstract:

In this study, two different polyhedral oligomeric silsesquioxane (POSS) were synthesized using 3-aminopropyltriethoxysilane (APTES) and N-(2-aminoethyl)-3- aminopropyltrimethoxysilane (AEPTMS). POSS Schiff bases were synthesized as a result of the condensation reaction of POSS compounds with salicylaldehyde and 5-bromosalicylaldehyde. The structures of POSS and its ligand derivatives were by spectroscopic (Elemental analysis (C, H, N), 1HNMR, 29Si-NMR, FT-IR) methods. Cu(II) and Ni(II) metal complexes of Schiff Bases were also synthesized. The structures of the isolated POSS Schiff base metal complexes were tried to be clarified with FT-IR, Magnetic susceptibility balance and ICP-OES. The results showed that metal ions bind to Schiff bases via phenolic oxygen and azomethine nitrogen.
