Synthesis and Investigation of Electrochromic Component Stimuli- Esponsive Based on Aniline Pentamer
, M.Sc. Thesis Sharif University of Technology ; Pourjavdi, Ali (Supervisor)
Abstract
The use of polyaniline as an electrochromic conductive polymer was highly regarded. However, due to problems such as poor solubility, the researchers decided to use aniline oligomer as an alternative. Meanwhile, aniline pentamer received more attention due to its good solubility in organic solvents and acceptable conductivity. On the other hand, it is possible to increase the conductivity and also to respond more to stimuli to groups that have certain characteristics. In this study, aniline pentamer and carbazole-derived were used. First, nitro and bromoethanol groups are added to carbazole. Due to its fluorescence properties, carbazole can, in addition to increasing the conductivity, which...
Synthesis, Characterization and Emission Study of Carbazole-Based Platinum(II) Pincer Complexes and their Emission Properties
, M.Sc. Thesis Sharif University of Technology ; Jamali, Sirous (Supervisor)
Abstract
Platinum(II) complex [Pt(Carb-PPh2)Cl] (1) (Carb-PPh2 = 1,8-bis(phosphino)-3,6-di-tert-butyl carbazole) was synthesized from the reaction of K2[PtCl4] salt with PNP carbazole-based pincer ligand, 1,8-bis(phosphino)-3,6-di-tert-butyl carbazole (c) and LiHMDS in a 1:2:1.1 molar ratio. The structure of 1 was characterized by X-ray crystallography in solid state, NMR spectroscopy, UV-Vis spectroscopy, and photoluminescence spectroscopy in solution state. Platinum(II) complex [Pt(Carb-PPh2)(C≡CPh)] (2) was prepared from the reaction of complex 1 with phenylacetylene with a 3:1 molar ratio in the presence of CuI as a catalyst and triethylamine. Complex 2 was identified by NMR spectroscopy, UV-Vis...
Synthesis of Naphtalimide and Carbazole Based Ligands and their Complexes with Copper and Ruthenium Metals
, M.Sc. Thesis Sharif University of Technology ; Jamali, Sirous (Supervisor)
Abstract
In this work, we aimed to synthesize new naphthalimide and carbazole derivatives containing functional donor groups that can act as suitable ligands. To this end, the N-pyridyl carbazole ligand (3) and N-benzoic acid naphthalimide (9) were prepared via C-N bond coupling and condensation reactions between the corresponding carbazole and naphthalimide starting materials and 4-iodopyridine and 4-aminobenzoic acid, respectively. The reaction of compounds (3) and (9) with the copper (I) precursor complex CuI and the paddlewheel dimeric complex Ru2 (acetate)2Cl2 yielded the tetranuclear copper (I) cluster Cu4I4(N-pyridyl carbazole)4 (Compound A) and the paddlewheel dimeric complex...
