Synthesis, Characterization, and Study of Electrochemical Behavior of N-alkyl Substituted Polycarbazole Derivatives

Abstract

Poly(9-dodecylcarbazole) (PDDC) and poly[(9-dodecylcarbazole)-co-thiophene] (PDDCT) were synthesized via oxidative coupling method using FeCl 3 and the polymers exhibited good solubility in polar aprotic solvents. The synthesized polymers were characterized using UV-visible, FTIR, 1 H-NMR spectroscopic techniques. The polymers exhibited thermal stability up to 300 C. The absorption spectra showed the maximum absorption peak at 414 and 443 nm (k max ), respectively, for PDDC and PDDCT. The electrochemical analysis revealed that the band gaps calculated for PDDC and PDDCT are 2.21 eV and 1.91 eV, respectively. The study of anodic peak current against scan rate showed that the electrochemical process is diffusion-limited.

Study of Optical and Photovoltaic Properties of N-Alkyl Substituted Polycarbazole Derivative and Its Copolymer with Thiophene

“…RESULT AND DISCUSSIONS Synthesis, characterization, and study of thermal and electrochemical properties of PDDC and PDDCT are reported elsewhere [27]. The physical properties of the polymers are summarized in Table 1.…”

“…Poly(9-dodecylcarbazole) (PDDC) and poly[(9-dodecylcarbazole)-co-thiophene] (PDDCT) were synthesized by the process reported elsewhere [27]. These two polymers were used as donor material in fabricating polymeric solar cells and photovoltaic properties of the same were studied.…”

Electrodeposition and Thin Film Formation of Hyperbranched Poly(N-Vinylcarbazole) on Indium-Tin-Oxide Substrates

“…While there are many studies reported on the electrodeposition of linear and dendrimeric forms of PVK, there appears to be a limited number of researches on hyperbranched PVK (Macit et al, 2005;Boudreault et al, 2010;Tria et al, 2010;Pokhrel et al,2011;. In this paper we report the synthesis of a new architecture of poly(Nvinylcarbazole) though reversible additionfragmentation chain transfer polymerization and the polymer's electrodeposition on a conducting substrate to form thin films.…”
