Energy level, band gap, and hole mobility of photovoltaic donor polymers are crucial factors in achieving high power conversion efficiency. Controlling these characteristics, however, requires complicated synthesis routes. This work reports an effective way to control these properties simultaneously by introducing a simple terpolymer system. Simulation of energy level (band gap), synthesis of donor polymers, and calculation of solubility were systematically coordinated to explain the advantages of the terpolymer system. Anthradithiophene was introduced to elucidate the effect of the extended conjugation length on band gap and hole mobility of donor polymers. Benzodithiophene and thienothiophene which have shown good properties in bulk heterojunction organic solar cells were used as comonomers. Based on the result of the energy level calculation, terpolymers with various mole ratios of the monomers were synthesized; as the ratio of anthradithiophene to benzodithiophene increased, band gap of the terpolymers decreased while hole mobility increased. In addition, we explained the morphol. of the terpolymer:fullerene bulk heterojunction films using solubility parameters of materials. With this method, we investigated the relationship between the properties of donor polymers and device performances systematically. The terpolymer system can be widely utilized for tuning the material properties in a systematic way which is quite similar to the band gap engineering in the inorganic semiconductors. The results came from multiple reactions, including the reaction of 2-(Thiophen-3-yl)-1,3-dioxolane(cas: 13250-82-3Product Details of 13250-82-3)

A two-step synthesis of benzo[1,2-b:4,5-b’]dithiophene (BDT) was carried out starting from 3-thiophene carbaldehyde as the sole thiophene precursor. This method involved the selective lithiation of the 2-position of 3-thiophenecarbaldehyde ethylene acetal, followed by the condensation with 3-thiophenecarbaldehyde and subsequent dehydrative cycloaromatization of the dithienylmethanol intermediate to give BDT. This synthetic pathway was extended to other thiophene benzocondensed heterocycles, e.g., I.

《Metalation of 3-thiophenecarboxaldehyde ethylene acetal-the tautomeric structure of 3-formyl-2-thiophenecarboxylic acid》 was published in Arkiv foer Kemi in 1963. These research results belong to Gronowitz, Salo; Gestblom, Bo; Mathiasson, Birgitta. Category: benzothiophene The article mentions the following:

Metalation of 3-thiophenecarboxaldehyde ethylene acetal, b10 103-4°, with BuLi, followed by carbonation gave 78% 3formyl-2-thiophenecarboxylic acid (I), m. 130-1° (C6H6-ligroine). I was identified by mutual coupling of the thiophenic ring hydrogens at 5.2 cycles/sec. in the nuclear magnetic resonance (n.m.r.) spectrum and Ag2O oxidation of I to 2,3-thiophenedicarboxylic acid. The infrared spectrum of I in KBr showed C:O stretching frequencies at 5.87 and 6.09 μ, and no OH stretching absorption at 3 μ. I gave no Me ester on refluxing with MeOH without acid, but with acid a Me ester (II), m. 61-2°; v 5.81, 5.96 μ (KBr). Thus, I must exist in the open aldehydocarboxylic acid structure. The n.m.r, spectra are given for I, II, phthalaldehydic acid (III), the Me ester of III, and the anion of III in Me2CO, dioxane, CHCl3, and H2O. These spectra support the open form of I and the cyclic nature of III.

The author of 《Benzodithiophenes. A general method of synthesis》 were Gronowitz, Salo; Dahlgren, Torsten. And the article was published in Chemica Scripta in 1977. Recommanded Product: 2-(Thiophen-3-yl)-1,3-dioxolane The author mentioned the following in the article:

Through the Wittig reaction between o-bromoformylthiophenes and o-bromothenyltriphenylphosphoranes all six cis-1,2-di(o-bromothienyl)ethenes could be obtained. Halogen-metal exchange of these compounds with BuLi followed by reaction with CuCl2 yielded all six benzodithiophenes which are analogous to phenanthrene, namely benzo[1,2-b:4,3-b’]dithiophene, benzo[2,1-b:3,4-b’]dithiophene, benzo[1,2-b:3,4-b’]dithiophene, benzo[1,2-b:3,4-c’]dithiophene, benzo[2,1-b:3,4-c’]dithiophene and benzo[1,2-c:3,4-c’]dithiophene. The [b,c]-fused systems, although relatively stable in solution, could not be isolated due to dimerization or polymerization They could be characterized by reaction with di-Me acetylenedicarboxylate. After S extrusion, 7,8-dicarbomethoxynaphtho[2,1-b]thiophene and 7,8-dicarbomethoxynaphtho[1,2-b]thiophene are formed from the corresponding cycloaddition products.

Kraft, Ulrike; Anthony, John E.; Ripaud, Emilie; Loth, Marsha A.; Weber, Edwin; Klauk, Hagen published an article on February 10 ,2015. The article was titled 《Low-Voltage Organic Transistors Based on Tetraceno[2,3-b]thiophene: Contact Resistance and Air Stability》, and you may find the article in Chemistry of Materials.Quality Control of 2-(Thiophen-3-yl)-1,3-dioxolane The information in the text is summarized as follows:

The small-mol. organic semiconductor tetraceno[2,3-b]thiophene was synthesized through an environmentally friendly synthetic route, using NaBH4, rather than Al/HgCl2, for the reduction of the quinone. Low-voltage organic thin-film transistors (TFTs) were fabricated using tetraceno[2,3-b]thiophene and, for comparison, pentacene and anthradithiophene as the semiconductor. The tetraceno[2,3-b]thiophene TFTs have an effective field-effect mobility as large as 0.55 cm2 V-1 s-1 and a subthreshold swing of 0.13 V/decade. The contact resistance of the tetraceno[2,3-b]thiophene TFTs is substantially smaller than that of the anthradithiophene TFTs and similar to that of the pentacene TFTs. The long-term air stability of TFTs based on all three semiconductors was monitored over a period of 12 mo. The initial charge-carrier mobility of the tetraceno[2,3-b]thiophene TFTs is ∼50% smaller than that of the pentacene TFTs, but as a result of the greater ionization potential and better air stability induced by the terminal thiophene ring condensed at the thiophene-b-bond, the tetraceno[2,3-b]thiophene TFTs outperform the pentacene TFTs after continuous exposure to ambient air for just 3 mo. In the experimental materials used by the author, we found 2-(Thiophen-3-yl)-1,3-dioxolane(cas: 13250-82-3Quality Control of 2-(Thiophen-3-yl)-1,3-dioxolane)
