Abstract

We measured detailed photophysical properties of 1,4-bis(4-trifluoromethylstyryl)benzene (3PV-CF3). 3PV-CF3 showed a high fluorescence quantum efficiency and a high radiative rate constant. Furthermore, we evaluated the emission behavior of 3PV-CF3 under excitation of femtosecond laser pulses. Microcrystals of 3PV-CF3 were prepared easily by spin-coating, and were confirmed for amplified spontaneous emission. It has a low threshold of 34 µJ cm−2.
