An interesting and important question emerges with the rapid advances of the highly efficient fused-ring nonfullerene acceptors; i.e., how the acceptor mols. form aggregates in its blended film with a donor polymer/small mol. so as to offer highly efficient exciton diffusion and electron transport. To answer this question, a new acceptor mol., 3,9-bis(5-methylene-4-one-6-(1,1-dicyanomethylene)-cyclopenta[c]thiophen-2,8-dimethyl)-5,5,11,11-tetrakis(4-n-hexylphenyl)-dithieno[2,3-d:2′,3′-d’]-s-indaceno[1,2-b:5,6-b’]dithiophene (ITCT-DM), is designed and synthesized herein and its unique interpenetrating J-architecture is presented in which the acceptor mols. form compacted and displaced ππ-stacks with the distances of 3.1-4.2 Ǻ. Again the crystal structure data are correlated with the grazing-incidence X-ray diffraction (GIXRD) data of the pure acceptor and its polymer:acceptor blended films, which gives a clearer picture about the origins of the acceptor’s GIXRD signals in both the pure and its blended films. Again, these results unveil the key roles of the uses of 1,8-diiodooctane (DIO) and thermal annealing treatment in optimizing the acceptor phase morphologies in the donor:acceptor blended film, and the combination of the thermal annealing and DIO treatment leads to obtain higher crystallinity for both the donor and acceptor phases, more compacted packing, and finer morphologies. A power conversion efficiency of 10.5% is obtained. This study involved multiple reactions and reactants, such as 2,5-Dimethylthiophene (cas: 638-02-8HPLC of Formula: 638-02-8).
2,5-Dimethylthiophene (cas: 638-02-8) belongs to benzothiophene derivatives. Benzothiophene is used as starting material for the synthesis of bioactive molecules. The core structure is a part of various pharmaceutical substances and natural products. Due to its aromaticity, thiophenes do not exhibit the same properties as conventional thioethers.HPLC of Formula: 638-02-8
