Donor-acceptor (D-A) conjugated polymers have gotten significant attention in the past decades. Wide application area, ease of production, and cost-effectiveness have made the D-A conjugated polymers a pivotal class of organic electronics. Organic solar cells (OSCs) became one of the most critical application areas of conjugated polymers among many. Up to the last decade, intensive research has been conducted on fullerene-based OSCs. Drawbacks of fullerene derivatives like high cost, production obstacles, and difficulties in modifying molecular structure made the academia seek new alternatives. Emerging nonfullerene acceptors (NFAs) draw a new path for academia to tune OSCs' power conversion efficiency (PCE). With the ease of synthesis and purification, modification of molecular structure via various functional groups, NFAs start outperforming fullerene-based acceptors. Thieno[3,4-c]pyrrole-4,6-dione (TPD) is widely used in D-A conjugated polymers for high-performance OSCs. As a strong electron-withdrawing group, TPD provides deepened lowest unoccupied molecular orbital energy level and wide bandgaps when introduced into polymer backbones, enhancing optoelectronic properties photovoltaic performance. Herein, an overview of the applications ofTPD-based donor and acceptor type conjugated polymers for nonfullerene and all-polymer solar cells in the last 5 years is provided.

Bicyclic strained allenes : incorporation of an allene unit into alpha-pinene and benzonorbornadiene
Kılbaş, Benan; Balcı, Metin; Department of Chemistry (2009)
The synthesis of cyclic allenes with eight or less skeletal C-atoms, known as highly strained organic compounds, has for the past decades attracted increasing interest. The first part of study describes an investigation aimed at the incorporation of an allene unit into a natural compound, being α-pinene, by using β-elimination method. The two double-bond isomers 310 and 299b were synthesized as key compounds. Treatment of 310 with t-BuOK resulted in the formation of ketone 308 and diene 313. For the formati...
Isomerization of 4,6-DinitrobenzofuroxanA DFT Study
Türker, Burhan Lemi (2011-01-01)
The present study concentrates on the isomerization process of 4,6-dinitrobenzofuroxan and the monoionic forms of its bicyclic isomers. The ionic forms shed some light on the stability of those isomers in an ionizing electric field or static charging. To achieve the goals of the study, certain density functional theory (DFT) calculations have been carried out at the restricted and unrestricted levels of B3LYP using 6-31G(d) and 6-311+G(d,p) basis sets. The stabilities and some other quantum chemical propert...
Syntheses of conjugated polymers and investigation the effect of gold nanoparticle - thiol interaction for organic solar cell application
Gülmez, Selin; Çırpan, Ali; Department of Chemistry (2022-8-31)
In this thesis, five benzo[c][1,2,5] thiadiazole-based conjugated polymers were synthesized. Four of them were synthesized via Stille and Suzuki coupling reactions and the remaining one was synthesized by post-polymerization. The effect of functional groups of the tip of the alkyl chain was analyzed. Moreover, thiol group and gold nanoparticle interaction on the organic solar cell efficiency for P1-SH were investigated. Electronic and optical band gaps of polymers were found as 1.85/1.81, 1.95/1.85, 1.83/1....
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...
Naphthazarin-Polycyclic Conjugated Hydrocarbons and Iptycenes
Dengiz, Çağatay; GUTIERREZ, Gregory D.; SWAGER, Timothy M. (American Chemical Society (ACS), 2017-07-21)
The synthesis of a set of naphthazarin-containing polycyclic conjugated hydrocarbons is described herein. Sequential Diels-Alder reactions on a tautomerized naphthazarin core were employed to access the final conjugated systems. Complete conjugation across the backbone can be achieved through complexation with BF2, as observed by (HNMR)-H-1 analysis and UV/vis spectroscopy. Precise synthetic control over the degree of oxidation of naphthazarin quinone Diels-Alder adduct 10 is additionally demonstrated and e...
