Metal oxides represent an abundant and non-toxic class of photocatalysts for organic transformations. However, their use in larger scale processes is complicated by incompatibilities with continuous flow processing - a proven scale-up route for photochemi

Perylene diimides (PDIs) and their derivatives are excellent semiconductors, while conjugated polymers based on PDIs have limited applications because of their low electron mobility (μe) derived from low molecular weight. The reported maximum number-average molecular weight (Mn) of related polymers is only 21 kDa because PDIs have very poor solubility due to strong π–π stacking of their big planar conjugated cores. Herein, it is found that suitable semi-perfluoroalkyl groups could enhance the solubility of PDIs significantly, and a series of semi-perfluoroalkyl modified conjugated polymers with high molecular weight and electron mobility were synthesized. The maximum Mn reaches 94.8 kDa [P(4CF8CH-PDI-T2)HW]. In their space-charge-limited current (SCLC) devices, all polymers exhibit typical characters of electron transporting semiconductors, and the highest μe is up to 8.40 × 10?3 cm2?V?1?s?1 [P(4CF8CH-PDI-T2)HW], which is similar as that of widely used electron transporting semiconductor PC61BM (6.41 × 10?3?cm2?V?1?s?1).
Radical addition of perfluoroalkyl iodides to alkenes and alkynes initiated by sodium dithionite in an aqueous solution in the presence of a novel fluorosurfactant
Xiao, Zhiwei,Hu, Huawei,Ma, Jiaoli,Chen, Qingyun,Guo, Yong
, p. 939 - 944 (2013/08/23)
A new fluorinated anionic surfactant Cl(CF2) 6O(CF2)2SO3N(C2H 5)4 was prepared and characterized. The application of the fluorosurfactant allowed the fluoroalkylation to occur in the water without adding organic solvent. The addition of perfluoroalkyl iodides with olefins and alkynes under the initiation of Na2S2O4 in water in the presence of the fluorosurfactant gave the corresponding adducts in good to excellent yields. The fluorosurfactant was suitable for a radical addition process. A new surfactant Cl(CF2)6O(CF 2)2SO3N(C2H5) 4 was prepared and its properties were measured. The fluorinated surfactant was applied to the fluoroalkylation of perfluoroalkyl iodides with olefins and alkynes. The reactions gave the corresponding adducts in water and avoided the use of organic solvent. The aqueous solution with the surfactant proved to be an effective medium for a radical process.
