摘要
Theoretically,1,2,3-benzotriazole（BT）-based derivative is designed by the struc-tural tuning in 2,1,3-benzothiadiazole（BTD）-based derivative and presents potential for applications in organic light-emitting diodes（OLEDs）.Calculations show that the emission spectrum of BT-based derivative is located at the blue scope,so it can act as a blue-light-emitting material.Importantly,the oscillator strength of emission spectrum is significantly enhanced by replacing BTD with BT,implying it possess large fluorescent intensity.Additionally,BT-based derivative exhibits improved hole transportation with respect to the BTD-based derivative.
