Siloles are promising luminescent materials for the creation of organic light-emitting diodes (OLEDs). Attempts were made to create siloles with 4-bromophenyl, 4-t-butylphenyl, 4-trifluoromethylphenyl, and 4-trimethylsilylphenyl substituents on the 2,3,4,5-positions of the silole by using a nickel-catalyzed synthesis first proposed by Kumada in 1972. These particular substituents were chosen to compare and contrast the effects on the photophysical properties based on electron-donating versus electron-withdrawing groups. All products were characterized using proton, carbon, and silicon NMR, UV-vis absorption, melting point, and fluorescence. Further testing was done on successfully synthesized siloles to create OLED devices to test for quantum efficiencies.
