Piperidin, heterosiklik moleküller arasında en iyi bilinen yapılardan biridir. Güncel çalışmalar bu tür bileşiklerin yapı-doğrusal olmayan optiksel performans ilişkisine odaklanmaktadır. Doğrusal olmayan optik malzemelerin fiber optik iletişim ve optik sinyal işlemlerinde hayati öneme sahip oldukları bilinmektedir. Bu çalışmada, bir piperidin türevi olan cis-2,6-bis(2-klorofenil)-3,3-dimetilpiperidin-4-one (2C3DMPO) bileşiğinin yapısal, spektroskopik, elektronik ve doğrusal olmayan optik özellikleri analiz edilmiştir. 2C3DMPO için elde edilen teorik sonuçlar deneysel değerler ile iyi bir uyum içindedirler. NMR spektrumunda, elektronegatif O atomundan dolayı, C4 atomu aşağı alanda sinyal vermiştir. HOMO ve LUMO arasındaki küçük enerji aralığı, bağ ve antibağ yörüngeleri arasındaki yoğun etkileşmeler yüksek doğrusal olmayan optik özelliklerin göstergesidir.

Structural, spectroscopic, electronic and nonlinear optical investigations on cis-2,6-bis(2-chlorophenyl)-3,3-dimethylpiperidin-4-one

Öz

Piperidine is one of the most recognizable structural entities among heterocyclic molecules. The current studies have been focused on structure–nonlinear optical performance relationship of such compounds. It is well known that the nonlinear optical materials play a vital role in the field of fiber optic communications and optical signal process. In this study, cis-2,6-bis(2-chlorophenyl)-3,3-dimethylpiperidin-4-one (2C3DMPO) compound which is a piperidine derivate has been analyzed in terms of structural, spectroscopic, electronic and nonlinear optical properties. Obtained theoretical results for 2C3DMPO are in good agreement with previously reported experimental data. In NMR calculations C4 atom gives signal at downfield region due to bonding electronegative O atom. The small energy gap between HOMO and LUMO energies, and the intensive interactions between the bonding and antibonding orbitals are indicators of high nonlinear optical properties.
