Selenophene Based Benzodithiophene And Quinoxaline Containing Alternating Conjugated Polymers For Bulk-Heterojunction Solar Cell Applications
Çırpan, Ali; Cevher, Şevki Can (2018-09-12)
Selenophene bearing benzodithiophene based alternating polymers for organic solar cell applications
Özkul Atlı, Gülten; Çırpan, Ali; Department of Chemistry (2019)
The current research trends have greatly focused on the development of new low band gap conjugated polymers featuring alternating donor-acceptor unities to achieve remarkable power conversion efficiencies for OPV devices. For this purpose, a series of new quinoxaline and selenophene based BDT bearing conjugated polymers namely P1, P2 and P3 were synthesized using Stille cross coupling reaction. The 2-(2-Octyldodecyl)selenophene ring was attached to 4th and 8th positions of phenyl ring in BDT to obtain donor...
Selenophene-containing conjugated polymers for supercapacitor electrodes
Yildiz, Dilber Esra; Cevher, Duygu; Yasa, Mustafa; Çırpan, Ali; Toppare, Levent Kamil (2021-10-01)
In recent years, studies on conjugated polymers have strengthened the researchers' thought that such polymers can play an essential role in developing new generation energy storage devices. Hence conjugated polymer supercapacitor studies have accelerated. In the present work, selenophene-containing conjugated polymers previously synthesized via palladium-catalyzed Suzuki polymerization reaction were used in the preparation of conjugated polymer-based supercapacitor electrodes. The structure and surface morp...
Selenophene-bearing low-band-gap conjugated polymers: tuning optoelectronic properties via fluorene and carbazole as donor moieties
Yasa, Mustafa; GÖKER, SEZA; Toppare, Levent Kamil (Springer Science and Business Media LLC, 2020-05-01)
In this study, two donor-acceptor (D-A)-type conjugated polymers, namely PQSeCz and PQSeFl, were designed and synthesized. Selenophene was incorporated as the pi-bridge and quinoxaline as an acceptor unit, while carbazole and fluorene were used as the donor units. Polymers were synthesized via palladium-catalyzed Suzuki polymerization reaction. All molecules were characterized by H-1 and C-13 NMR spectroscopy. The weight and number average molecular weights of the two polymers were determined by gel permeat...
Selenium containing conducting polymer based pyranose oxidase biosensor for glucose detection
Gokoglan, Tugba Ceren; SÖYLEMEZ, SANİYE; Kesik, Melis; Toksabay, Sinem; Toppare, Levent Kamil (2015-04-01)
A novel amperometric pyranose oxidase (PyOx) biosensor based on a selenium containing conducting polymer has been developed for the glucose detection. For this purpose, a conducting polymer; poly(4,7-bis(thieno[3,2-b]thiophen-2-yl)benzo[c][1,2,5] selenadiazole) (poly(BSeTT)) was synthesized via electropolymerisation on gold electrode to examine its matrix property for glucose detection. For this purpose, PyOx was used as the model enzyme and immobilised via physical adsorption technique. Amperometric detect...
