The analysis is performed by Raman and UV/Vis absorption/excitation/fluorescence spectroscopy in combination with density functional calculations. Theoretical calculations show that substitution with carbonyl groups and perfluorohexyl chains induces progressive quinoidization of the π‐conjugated backbone in comparison to the carbonyl‐free compound 5,5′′′‐dimethyl‐2,2′:5′,2′′:5′′,2′′′‐quaterthiophene (DM‐4T) used as reference. Raman spectra are dominated by a strong Raman line which mainly corresponds to a combination of CC/CC stretching vibrations spreading over the whole thiophene core. This band undergoes a remarkable downshift as a consequence of the structural changes induced by the electron‐withdrawing groups on the π‐conjugated backbone. The band splitting on incorporation of a central carbonyl bridge evidences the formation of two structural domains in the molecule. The excitation and fluorescence spectra recorded at low temperature show well‐resolved vibronic structures associated with the most intense collective CC/CC stretching mode. Optical absorption and fluorescence bands exhibit remarkable bathochromic dispersion on carbonyl functionalization, indicative of extension of π conjugation. TDDFT calculations enable a detailed description of the trends observed in the absorption spectra. Resonance Raman spectra reflect the structural changes predicted for the S0→S1 electronic transition and evidence the cross‐conjugated character that the central carbonyl group confers on 3.},

abstract = {AbstractHerein, we report a new family of naphthaleneamidinemonoimide‐fused oligothiophene semiconductors designed for facile charge transport in organic field‐effect transistors (OFETs). These molecules have planar skeletons that induce high degrees of crystallinity and hence good charge‐transport properties. By modulating the length of the oligothiophene fragment, the majority carrier charge transport can be switched from n‐type to ambipolar behavior. The highest FET performance is achieved for solution‐processed films of 10‐[(2,2′‐bithiophen)‐5‐yl]‐2‐octylbenzo[lmn]thieno[3′,4′:4,5]imidazo[2,1‐b][3,8]phenanthroline‐1,3,6(2 H)‐trione (NDI‐3 Tp), with optimized film mobilities of 2×10−2 and 0.7×10−2 cm2 V−1 s−1 for electrons and holes, respectively. Finally, these planar semiconductors are compared with their twisted‐skeleton counterparts, which exhibit only n‐type mobility, in order to understand the origin of the ambipolarity in this new series of molecular semiconductors.},
