“…There are many recent examples of high performing co-polymers with benzothiadiazole. 16 An exemplary case is the donor polymer developed through a collaboration between UCSB and Konarka, which is an alternating copolymer of benzothiadiazole and dialkylated cyclopentabithiophene, 17 commonly known as PCPDTBT (poly [2,6- Fig. 4.…”

In this tutorial review, we discuss the factors responsible for influencing blend microstructure and how these affect device performance. In particular we discuss how various molecular design approaches can affect the thin film morphology of both the donor and acceptor components, as well as their blend microstructure. We further examine the influence of polymer molecular weight and blend composition upon device performance, and discuss how a variety of processing techniques can be used to control the blend microstructure, leading to improvements in solar cell efficiencies.

“…The most notable structural difference between these derivatives and the alkylbased DASAs is the presence of an aromatic ring, where homoconjugation may result in a bathochromic absorption shift due to enhanced hybridization of molecular orbitals between the electron-rich donors and acceptor groups, an effect commonly observed with "push-pull" systems in organic semiconductors. 35,36 Using readily available aniline-based donors, the absorbance maxima of barbituric-based DASAs were tuned from 582 to 669 nm.…”

A class of tunable visible and near-infrared donor−acceptor Stenhouse adduct (DASA) photoswitches were efficiently synthesized in two to four steps from commercially available starting materials with minimal purification. Using either Meldrum's or barbituric acid "acceptors" in combination with aniline-based "donors", an absorption range spanning from 450 to 750 nm is obtained. Additionally, photoisomerization results in complete decoloration for all adducts, yielding fully transparent, colorless solutions and films. Detailed investigations using density functional theory, nuclear magnetic resonance, and visible absorption spectroscopies provide valuable insight into the unique structure−property relationships for this novel class of photoswitches. As a final demonstration, selective photochromism is accomplished in a variety of solvents and polymer matrices, a significant advantage for applications of this new generation of DASAs.
