In the present study, we designed three novel compounds via the combination of two precious nitrogen-containing scaffolds; 1,4-dihydropyridine (DHP) and azole, in the same molecule. To synthesize the title compounds, initially, azolyl benzaldehydes were obtained through the nucleophilic aromatic substitution reaction of 4-fluorobenzaldehyde with pyrazole, imidazole or 1,2,4-triazole. Subsequently, an unsymmetrical Hantzsch reaction was applied to achieve DHP scaffold, thus the target molecules. After structural characterization, the effects of various azole rings on optical and non-linear optical (NLO) properties were investigated by computational methods. Band gaps, chemical hardness/softness, dipole moments, average polarizability, first hyperpolarizability values were computed for the target compounds at the CAM-B3LYP/6-31++G(d,p) level of theory. The comparable results confirmed the potential of DHP-azole hybrids to be utilized in NLO devices. The title molecules were further tested for their antibacterial and antifungal activities following the evaluation of their drug likeness properties. The compounds containing imidazole or triazole rings represented better antifungal properties than antibacterial activities. Molecular docking studies were performed in the catalytic site of lanosterol 14α-demethylase, CYP51, from Candida albicans to explain the obtained biological results and suggest molecular modifications to endow this class of molecules with improved antifungal effects.

Enhancing electrochemical and electrochromic performances of carbazole comprising monomer via copolymerization with 3,4-ethylenedioxythiophene (EDOT) Kalay, Isil; Yigit, Deniz; GÜLLÜ, Mustafa; DEPCİ, TOLGA; Toppare, Levent Kamil; Hacioglu, Serife O. (Elsevier BV, 2020-09-01) In this study, two novel electrochromic copolymers (CoP1.3 and CoP1.5) were synthesized via electrochemical methods and characterized. The comonomers used in the synthesis were 3,4-ethylenedioxythiophene (EDOT) and a carbazole comprising monomer; 9-(2-(4-(Phenyldiazenyl) phenoxy) ethyl)-3,6-di(thiophen-2-yl)-9H-carbazole (M1). Carbazole containing monomer (M1) and EDOT were combined with two different comonomer feed ratios, 1: 3 and 1: 5 respectively in order to investigate the effect of increasing EDOT amo...
Synthesis and characterization of novel quinoxalinebased and thieno[3,4-c]pyrrole-4,6-dione-based conjugated polymers and their applications in organic electronics Karabağ, Aliekber; Günbaş, Emrullah Görkem; Department of Polymer Science and Technology (2017) In this thesis novel quinoxaline-based and thieno[3,4-c]pyrrole-4,6-dione (TPD)- based monomers were firstly synthesized. Structural analysis of each material synthesized was performed with Nuclear Magnetic Resonance (NMR) Spectroscopy and High-Resolution Mass Spectroscopy (HRMS). Two novel quinoxaline-based monomers were polymerized with electrochemical and/or chemical polymerization whereas TPD-based monomer was polymerized with benzodithiophene-based acceptor via Stille coupling polycondensation reaction...
Electrochromic properties of a soluble conducting polymer of 1-benzyl-2,5-di(thiophene-2-yl)-1H-pyrrole Tarkuc, S.; Sahmetlioglu, E.; Tanyeli, Cihangir; Akhmedov, I. M.; Toppare, Levent Kamil (Elsevier BV, 2007-02-20) In this study, synthesis of a thiophene functionalized monomer, 1-benzyl-2,5-di(thiophene-2-yl)-1H-pyrrole (SNBS) was achieved. A new polythiophene derivative was synthesized by both chemical and electrochemical polymerization. The polymer synthesized via chemical oxidative method was soluble in organic solvents and characterized by nuclear magnetic resonance (H-1 and C-13 NMR) spectroscopy. The average molecular weight of the chemically synthesized polymer was determined by gel permeation chromatography (G...
Electrochemical synthesis of new conjugated polymers based on carbazole and furan units Oguzturk, H. Esra; TİRKEŞ, SEHA; Önal, Ahmet Muhtar (2015-08-01) In this study, synthesis of four new monomers; 3,6-di(2-furyl)-9H-carbazole (M1), 3,6-di(2-furyl)-9-ethyl-carbazole (M2), 2,7-di(2-furyl)-9-H-carbazole (M3), 2,7-di(2-furyl)-9-(tridecan-7-yl)-9H-carbazole (M4), was achieved via Stifle cross-coupling reaction. The monomers were electrochemically polymerized, via repetitive cycling in acetonitrile-tetrabutylammonium hexafluorophosphate electrolytic medium. Optical and electrochemical properties of the monomers and their corresponding polymers were investigate...
