2 1. Experimental Methods 1 H and 13 C MR spectra were recorded using 300 MHz ( 1 H), 75.4 MHz ( 13 C) spectrometers. All the data are given as chemical shifts δ (ppm) downfield from Si(CH 3 ) 4. Infrared (IR) spectra were recorded using FT-IR spectrometer. The samples of the solid compounds were performed in the form of KBr pellets. UV spectra of 10 5 M solutions of synthesized compounds in tetrahydrofuran (THF) were recorded using a microcell with an internal width of 1 mm. Steady state fluorescence spectra were recorded using spectrometer. Differential scanning calorimetry (DSC) measurements were carried out in a nitrogen atmosphere with at a heating rate of 10 ºC/min. Thermogravimetric analysis (TGA) were performed in a nitrogen atmosphere at a heating rate of 20 ºC/min. Cyclic voltammetry (CV) measurements were carried out by a three-electrode assembly cell. Ionization potentials (I p ) of the films of the synthesized compounds were measured by electron photoemission in air method. Hole drift mobilities were measured by a xerographic time of-flight (XTF) method. The thickness of the charge-transporting layers were 2 12 µm. The structures of the molecules were optimized using B3LYP density functionals and 6-31G* basis sets. Ground state calculation for the neutral and cationic molecules were performed with Hartree-Fock (HF) and density functional theory (DFT) calculation. Excitation energies were obtained with both configuration interaction singles (CIS) and time-dependent DFT (TDDFT) calculations. Unless stated otherwise, the basis set employed in all calculation in the present work was 6-31G*, and the B3LYP functional was used in all DFT and TDDFT calculations. All calculations were performed with a developmental version of Q-Chem. S2
