Abstract

Summary form only given. Semiconducting 6,7,15,16-tetrakis(alkylthio)quinoxalino [2´,3´ :9,10] -phenanthro[4,5 - abc]phenazine, TQPP-[SR]₄ for R= C₁₂H₂₅, C₁₀H₂₁, C₈H₁₇, and C₆H₁₃ has been synthesized as a solution-processable potential charge transport material for organic electronics applications (Kaafarani et al., 2007). We characterize the microstructure of TQPP-[SR]₄ in films using a combination of polarized photon absorption spectroscopies (X-ray, vis, and infrared), X-ray diffraction, and scanning probe techniques. This effective characterization strategy allowed the complete determination of crystal order and molecular orientation within thin films of this complex molecule.
