“…The fusion of aromatic rings affects the aromaticity of all units, and so the five-membered ring in carbazole molecule is less aromatic than in the free pyrrole. Analyzing the results, we observed that the most sensitive aromaticity index is the zz component of NICS (1). The data from Table 5 were recalculated and presented graphically in Fig.…”

DFT and experimental studies on structure and spectroscopic parameters of 3,6-diiodo-9-ethyl-9H-carbazole

et al. 2015

The first report on crystal and molecular structure of 3,6-diiodo-9-ethyl-9H-carbazole is presented. Experimental room-temperature X-ray and 13 C chemical shift studies were supported by advanced theoretical calculations using density functional theory. The 13 C nuclear magnetic shieldings were predicted at the non-relativistic and relativistic level of theory using the zeroth-order regular approximation. Theoretical relativistic calculations of chemical shifts of carbons C3 and C6, directly bonded to iodine atoms, produced a reasonable agreement with experiment (initial deviation from experiment of 44.3 dropped to 4.25 ppm). The changes in ring aromatic character were estimated via a simple harmonic oscillator model of aromaticity and nucleus-independent chemical shift index calculations. A good linear correlation between experimental and theoretically predicted structural and NMR parameters was observed.

“…have greater solubility than rigid-rod conjugated polymers, facilitating thus their processing as thin films from solution. In the class of carbazole-based polymers, an important place is taken by poly (N-vinylcarbazole) (PVK) because it is easily synthesized and soluble in common organic solvents [15]. The controlled radical polymerizations of N-vinyl carbazole (VK) monomers are considered to be difficult because radical precursors are highly reactive due to the nature and strong electron donating pendant groups [16,17].…”

Abstract. benzyl methacrylate] with well-defined molecular weight and low polydispersity was prepared by atom transfer radical polymerization (ATRP) using 4-(diphenylamino) benzyl 2-bromo-2-methyl-propanoate as initiator and CuBr/2,2!-bipyridine as catalytic complex. Electrochemical behavior and optical properties of the polymers were investigated by cyclic voltammetry and UV-Vis and fluorescence spectroscopy. Cyclic votammetric studies revealed that the redox processes were accompanied by dimerization of triphenylamine pendant groups. The initial polymer was postmodified, in solution or bulk, by electrochemical oxidation leading to a crosslinked and insoluble network with electrochromic properties, accompanied by strong color changes with high coloration efficiency. The crosslinking reaction took place between triphenylamine groups through para free positions leading to tetraphenylbenzidine bridges. The structure of polymers was confirmed by Fourier transform infrared (FT-IR) spectroscopy and 1 H and 13 C-nuclear magnetic resonance spectroscopy. Morphology studies of the cross-linked film have evidenced a smooth and continuous aspect without any pinholes or defects.

“…In recent years, polymers with different optical properties have been attracted much attentions due to their applications in the sensors 1 , light-emitting diodes [2][3][4] , and others 5,6 . The optical properties of these materials can be easily tuned by controlling contents of the different concentrations.…”

In this research natural bio polymer "chitosan" was synthesized using fish shells, Chitosan is made from chitin by a chemical process involving demineralization (DA), deproteinization (DP) and deacetylation (DA). Chitosan was doped with (NiCl 2 ) by using casting method. The effects of addition of nickel chloride concentration optical properties of chitosan have been studied in the wavelength range (200-800) nm. The absorption coefficient, energy gap, refractive index and extinction coefficient have been determined. The results show that the optical constants change with increase of nickel chloride concentration.
