The perylene diimide substituted by thiophene rings at bay area shows photoactivity and can be used as a photo sensor, but another 1 substituted by mesitylene groups is photostable. The single crystal of 1,7-mesitylene perylenediimide was obtained. X-ray diffraction data of the crystal revealed that the plane of the perylene core was hardly twisted by introduction of mesitylene groups. These mesitylene groups are like clips maintaining the planarity of the perylene core. D. functional theory calculation was applied to study the difference of photophys. and photochem. properties. The discovery is valuable for design guidance of perylenediimides. Crystallog. data are given. This study involved multiple reactions and reactants, such as 2,5-Dimethylthiophene (cas: 638-02-8SDS of cas: 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. It is found within the chemical structures of pharmaceutical drugs such as zileuton, raloxifene, and sertaconazole, and also BTCP.SDS of cas: 638-02-8
