“…The EA of TIB−Si is the largest, which indicates that the electron transfer capability of TIB−Si is strong, and it was more advantageous of electrons injection . Comprehensive comparison of the original and designed molecules can be found that TIB−Si molecule has a smaller IP (5.41 eV) and a larger EA (2.15 eV), and TIB−Si has better charge transfer capability …”

The sulfur atoms on TIB were replaced by oxygen, nitrogen, phosphorus, silicon and selenium atoms to design a serial of new molecules. The bond lengths, dihedral angles, energy levels and energy gaps, ionization potentials, electron affinities, frontier molecular orbitals, absorption and fluorescence spectrums, reorganization energies and charge transfer rates of all molecules were calculated with density functional theory and the time‐dependent density functional theory methods. The results indicated that the structure and photoelectric properties of TIB have obvious changes after atoms substitution. Both sides of the structures of the designed molecules are distorted obviously. The energy levels, energy gaps, ionization potentials and electron affinities, adsorption and fluorescence spectrums, charge transfer and recombination rates of TIB−P and TIB−Si are better than that of other molecules. It is found that proper atoms substitution can effectively improve the photoelectric properties.

“…Some aspects of these isoindigo properties were briefly discussed in some reviews. [88][89][90][91][92] Synthetic applications of isoindigo are mainly based on the creation of polymeric structures. Variation of substituents both at the nitrogen atom and the side chain is directed towards improving the physical and chemical characteristics of the target compounds: solubility, UVvisible absorption, electron affinity and others.…”

Two indolo[3,2-b]carbazole (ICZ)-based polymers have been designed and synthesized using Sonogashira cross-coupling based on dibromoindolo[3,2-b]carbazoles and 2,7-diethynylfluorene or 9,10-diethynylanthracene. The 2, 8 positions of the ICZ moiety has been used for the bridging of arylene ethynylene structure to form the polymer backbone. The characterization has been done by Fourier transform infrared, proton nuclear magnetic resonance, ultraviolet-visible and (UV-vis) fluorescence spectroscopic methods. The polymers, moderately soluble in aprotic and chlorinated solvents, have been found to possess thermal stability above 300 C. The band gap examinations, executed through cyclic voltammetry and complemented by UV-vis studies, indicated their semiconducting nature and the possibility for their utilization for the fabrication of polymer solar cells and for optical switching applications. Interestingly, the new diethynylindolocarbazole systems have been found to act as Bronsted acid sensors as well as a Hg 2+ receptors.
