HPLC of Formula: 78-69-3In 2021, Murad, Ary R.;Iraqi, Ahmed;Aziz, Shujahadeen B.;Abdullah, Sozan N.;Brza, Mohamad A.;Saeed, Salah R.;Abdulwahid, Rebar T. published 《Fabrication of alternating copolymers based on cyclopentadithiophene-benzothiadiazole dicarboxylic imide with reduced optical band gap: synthesis, optical, electrochemical, thermal, and structural properties》. 《Polymers (Basel, Switzerland)》published the findings. The article contains the following contents:

A series of alternating copolymers containing cyclopentadithiophene (CPDT) flanked by thienyl moieties as electron-donor units and benzothiadiazole dicarboxylic imide (BTDI) as electron-acceptor units were designed and synthesized for solar cell applications. Different solubilizing side chains, including 2-ethylhexyl chains and n-octyl chains were attached to CPDT units, whereas 3,7-dimethyloctyl chains and n-octyl chains were anchored to the BTDI moieties. The impact of these substituents on the solubilities, mol. weights, optical and electrochem. properties, and thermal and structural properties of the resulting polymers was investigated. PCPDTDTBTDI-EH, DMO was synthesized via Suzuki polymerization, whereas PCPDTDTBTDI-8, DMO, and PCPDTDTBTDI-EH, 8 were prepared through direct arylation polymerization PCPDTDTBTDI-8, DMO has the highest number average mol. weight (Mn = 17,400 g mol-1) among all polymers prepared The PCPDTDTBTDI-8, DMO and PCPDTDTBTDI-8, 8 which have n-octyl substituents on their CPDT units have comparable optical band gaps (Eg ∼ 1.3 eV), which are around 0.1 eV lower than PCPDTDTBTDI-EH, DMO analogs that have 2-ethylhexyl substituents on their CPDT units. The polymers have their HOMO levels between -5.10 and -5.22 eV with PCPDTDTBTDI-EH, DMO having the deepest HOMO (HOMO) energy level. The LUMO (LUMO) levels of the polymers are between -3.4 and -3.5 eV. All polymers exhibit good thermal stability with decomposition temperatures surpassing 350 °C. Powder X-ray diffraction (XRD) studies have shown that all polymers have the amorphous nature in solid state. To complete the study, the researchers used 3,7-Dimethyloctan-3-ol (cas: 78-69-3) .
