Syntheses of benzodithiophene and thienopyrroledione containing conjugated random polymers as components for organic solar cells Azeri, Özge; Çırpan, Ali; Department of Chemistry (2017) In recent years organic solar cells (OSC) have attracted considerable attention as promising candidates for renewable energy technology because of their low cost, light weight and flexibility. In this study, in order to improve the efficiency of a bulk heterojunction solar cell, two conjugated random polymers were designed. For this purpose, benzodithiophene and thienopyrroledione containing two random copolymers were synthesized. The effects of several acceptors such as benzotriazole and benzothiadiazole o...
Syntheses and Characterization of Benzotriazole, Thienopyrroledione, and Benzodithiophene Containing Conjugated Random Terpolymers for Organic Solar Cells Goksu, Kardelen; Hizalan, Gonul; Udum, Yasemin Arslan; Hacioglu, Serife Ozdemir; Cevher, Sevki Can; Akrema, Akrema; Toppare, Levent Kamil; Çırpan, Ali (The Electrochemical Society, 2019-11-20) Two random terpolymers bearing alkoxy-benzodithiophene as an electron-rich unit and N-octylthieno[3,4,c]pyrrole-4,6-dione (TPD) as an electron deficient group with thiophene and selenophene pi bridges, were synthesized and characterized. Electrochemical, optical properties of the polymers were analyzed to get an insight on the effect of different p bridges. Photovoltaic performances of the polymers were investigated with a conventional device architecture. PBTS, PBTSe based polymer solar cells (PSCs) exhibi...

Syntheses and characterization of benzotriazole, thienopyrroledione and benzodithiophene containing conjugated random terpolymers for organic solar cells Göksu, Kardelen.; Çırpan, Ali; Department of Chemistry (2019) Two random terpolymers, PBTS and PBTSe were designed and synthesized successfully as the donor units for polymer organic solar cell. Desired terpolymers contain alkoxy-benzodithiophene as an electron rich unit and Noctylthieno[3,4,c]pyrrole-4,6-dione (TPD) as the electron deficient group. Furthermore, thiophene and selenophene π bridges were introduced to benzotriazole unit as the acceptor moieties into copolymer backbone. The properties of synthesized terpolymers solar cell device were investigated by opti...
Syntheses of novel fluorinated dibenzo[a,c]phenazine comprising polymers for electrochromic device applications Hacioglu, Serife O.; Aktas, Ece; Hizalan, Gonul; Akbasoglu, Naime; Çırpan, Ali; Toppare, Levent Kamil (2022-7-01) In this study, two novel fluorinated dibenzo[a,c]phenazine derivatives, 2,7-bis(5-bromo-4-hexylthiophen2-yl)-11-fluorodibenzo[a,c]phenazine (TFBPz) and 2,7-bis(2,3-dihydrothieno[3,4-b][1,4]dioxin-5-yl)-11- fluorodibenzo[a,c]phenazine (EFBPz), were synthesized by coupling fluorodibenzo[a,c]phenazine (FBPz) with electron rich 3-hexylthiophene and ethylene dioxythiophene (EDOT) units. The monomers were polymerized electrochemically and their electrochemical, spectroelectrochemical and electrochromic behavi...
