Annotation
Poly- and single crystalline films of 5,5′-bis(4-trimethylsilylbenzene-1-yl)-2,2′-bithiophene were grown for the first time and their photoluminescent properties were studied. Single crystalline films show exponential photoluminescence kinetics with a lifetime of 0.97 ns. Polycrystalline films demonstrate more complex photoluminescence kinetics. The relationship between the film structure and the photoluminescence kinetics is discussed.
