In this study, we introduced N-([1,1′-biphenyl]-2-yl)-N-(9,9-dimethyl-9H-fluoren-2-yl) spiro[dibenzo[a,d] [7]annulene-5,9′-fluoren]-2′-amine (BFS2A) and N-([1,1′-biphenyl] -2-yl)-N-(9,9-dimethyl-9H-fluoren-2-yl)spiro[dibenzo[a,d][7]annulene-5,9′-fluoren]-3-amine (BFS3A) as electron-blocking materials in organic light-emitting diodes (OLEDs). We verified that these materials have suitable optical properties as well as good electrochem. and thermal stability. Devices based on these materials also exhibited excellent charge balance, which corresponded to good device lifetime. Although BFS2A and BFS3A have similar mol. structures, OLEDs with these compounds as electron-blocking materials exhibited different performance, which we attributed to the differences in the modifying positions of the spiro backbone.Tris(dibenzylideneacetone)dipalladium(0)(cas: 51364-51-3Synthetic Route of C51H42O3Pd2) was used in this study.
Tris(dibenzylideneacetone)dipalladium(0)(cas: 51364-51-3) is used in the preparation of semiconducting polymers processed from nonchlorinated solvents into high performance thin film transistors.Synthetic Route of C51H42O3Pd2 It is also used in the synthesis of polymer bulk-heterojunction solar sells as a semiconductor.
