Electrochemical polymerization of a new alkoxy-bridged dithieno (3,2-B:2’,3’-D) pyrrole derivative

KIVRAK, Arif | YILDIZ, Hüseyin Bekir | GÖKYER, Selahattin | ÇARBAŞ, Buket

A novel alkoxy-bridged dithieno (3, 2-B:2’,3’-D) pyrrole (DTP) derivative was synthesized and its corresponding polymer poly(1,2-bis(2-(4H-dithieno[3,2-b:2’,3’-d]pyrrol-4-yl)ethoxy)ethane) (P(DTP-alkoxy-DTP)) was successfully obtained electrochemically. The e ﬀ ects of alkoxy bridge in the structure on the electrochemical and spectroelectrochemical properties of the polymer were also investigated in detail. The results showed that the polymer ﬁ lm exhibits multielectrochromic behavior and a low band gap of 1.82 eV.

Synthesis and characterization of a new poly (dithieno (3, 2-b: 2′, 3′-d) pyrrole) derivative conjugated polymer: Its electrochromic and biosensing applications

AZAK, Hacer | YILDIZ, Hüseyin Bekir | ÇARBAŞ, Buket

Synthesis and electropolymerization of a new conjugated dithieno(3,2-b:20,30-d) pyrole (DTP) derivative, namely, 2-(2-(2-(4H-dithieno[3,2-b:20,30-d]pyrrol-4-yl)ethoxy)ethoxy)ethanamine, (DTP-alkoxy-NH2) monomer are presented. The electrochemical, spectroelectrochemical effects and biosensor capability towards to glucose oxidase enzyme of P(DTP-alkoxy-NH2) polymer ﬁ lm are investigated in detail during the placement of alkoxy-NH2 functional unit in the polymer. Electrochemical and optical results between neutral and oxidized states of the polymer ﬁ lm show that (P(DTP-alkoxy-NH2)) has reversibl ...Daha fazlası

Construction of conducting polymer/cytochrome C/thylakoid membrane based photo-bioelectrochemical fuel cells generating high photocurrent via photosynthesis

ÇEVİK, Emre | ÇARBAŞ, Buket | ŞENEL, Mehmet | YILDIZ, Hüseyin Bekir

In this study, a photo-bioelectrochemical fuel cell was constructed for photocurrent generation by illuminating the electrodes within an aqueous solution. In this purpose, gold electrode was coated with poly 4-(4H-Dithieno [3,2-b:2′,3′-d]pyrol-4-yl) aniline, P(DTP-Ph-NH2) conductive polymer ﬁ lm by using electrochemical polymerization. Then, P(DTP-Ph-NH2) conductive polymer ﬁ lm coated surface was electrochemically modi ﬁ ed with cytochrome C which covalently linked onto the surface via bis-aniline functionality of the polymer ﬁ lm and formed crosslinked-structure. The thylakoid membrane was a ...Daha fazlası
