  Band Gap Control in Conjugated Oligomers via Lewis Acids

  摘要：

  A simple and effective strategy for optical band gap control is demonstrated through the use of a novel small acceptor/donor/acceptor molecule, 1, and group-13 Lewis acids. Chromophore 1 contains a dithienolesilole donor unit end-capped with benzo-2,1,3-thiadiazole (BT) acceptor units. Addition to 1 of stoichiometeric quantities of Lewis acids of varying strength resulted in the formation of Lewis adducts with progressively red-shifted primary charge-transfer absorption bands. These complexes have absorption spectra that approach those of known conjugated copolymers containing related units. NMR spectroscopy and X-ray diffraction studies revealed that 1 binds 2 equiv of Lewis acid via the nitrogen at the 3-position of BT.

  A method for altering the electronic and optical properties of a chemical compound having a band gap and a framework that includes π-delocalized electrons. The method includes complexing a Lewis acid to a basic site within the framework to form a Lewis acid adduct having a band gap that differs from the band gap of the chemical compound. The λ max of the Lewis acid adduct can be shifted to a longer wavelength in comparison to the λ max of the chemical compound. In various versions, the chemical compound can be a conjugated oligomer, a conjugated polymer, or a small molecule comprising a conjugated π-electron system. Electronic devices that include Lewis acid adducts are also provided.

  The transient absorption of radical cations of a variety of substituted polysilanes is discussed quantitatively in terms of the molar extinction coefficient and oscillator strength by nanosecond pulse radiolysis. Oxygen -saturated polysilane solutions in benzene exhibit a strong transient absorption band ascribed to the polysilane radical cation. The transient species react with N,N,N,N-tetramethyl-p-phenylenediamine (TMPD) to produce TMPD radical cations. On the basis of the molar extinction coefficient of the TMPD radical cation, the molar extinction coefficients for the radical cations of polysilanes are found to increase in the range 3.3 x 10(4) to 2.0 x 10(5) M(-1) cm(-1) with increasing polymer segment length. The stepwise increase in the total oscillator strength with an increase in the number of phenyl rings directly bonded to the Si skeleton suggests the delocalization of the positive polaron state and/or the SOMO state over the phenyl rings, indicating the importance of phenyl rings in intermolecular hole transfer processes.
