Effect of Electron-Withdrawing Substituents on Raman Spectra of Diaryl-BTBT Derivatives https://www.mdpi.com/1422-0067/27/11/5088
Abstract Low-frequency (LF, ν ≤ 200 cm −1) vibrational modes of crystalline organic semiconductors are of particular interest because they significantly affect charge transport in these materials. Herein, we study LF vibrations of [1]benzothieno[3,2-b][1]benzothiophene (BTBT) substituted by...
