Abstract

Karbazol (Cz), 9,9’-dikarbazil (DCz), 3,9’;9,9’’-trikarbazil (TCz) ve policarbazilin (PCz) tetrasiyanoetilen (TCNE) ve p-kloranil (p-CHL) akseptörleriyle yük-transfer (CT) kompleksleşmeleri spektroskopik olarak incelenmiştir. CT komplekslerinin bağıl kararlılıkları, termodinamik özellikleri ve stökiyometrileri donör moleküllerin moleküler yapılarını ve akseptör moleküllerin bağıl elektron ilgilerini temel alarak tartışılmıştır. Çalışma sonucunda DCz, TCz, ve PCz nin TCNE ve p-CHL ile monomerik analoğu olan Cz ye göre daha kararsız kompleks oluşturdukları sonucuna varılmıştır

Charge-Transfer Complexations of Oxidative Coupling Products of Carbazole with TCNE and P- Chloranil

Abstract

Charge-transfer (CT) complexations of 9H-carbazole (Cz), 9,9’-dicarbazyl (DCz), 3,9’;9,9’’-tricarbazyl tetracyanoethylene spectroscopically. The relative stabilities, thermodynamic properties and stoichiometries of the CT complexes were discussed based on the molecular structure of the donor molecules and relative electron affinities of the acceptor molecules. It is concluded that DCz, TCz, and PCz form less stable complexes with TCNE and p-CHL than their monomeric analogues Cz
