“…In this context, selenophenes and their derivatives have been widely studied due to their intrinsic biological activity [ 22 ], such as antidepressant [ 23 , 24 , 25 , 26 , 27 , 28 ], antioxidant [ 29 , 30 , 31 , 32 , 33 , 34 , 35 ], anticonvulsant [ 36 , 37 ], antibacterial [ 38 ], antitumor [ 39 , 40 , 41 , 42 , 43 , 44 , 45 , 46 , 47 ], antinociceptive [ 48 ], hepatoprotective [ 49 , 50 ] and antiapoptotic agents [ 51 ]. Besides, they have also played an important role in the materials science field, being used to build organic light emitting diodes (OLEDs) [ 52 , 53 , 54 , 55 , 56 , 57 , 58 ], organic field effect transistors (OFETs) [ 59 , 60 , 61 , 62 , 63 , 64 , 65 , 66 , 67 , 68 , 69 ], organic solar cells (OSC) [ 70 , 71 ...…”
