  摘要：

  The 2pπ*–3dπ interaction in the excited state of aromatic silanes has been studied by means of absorption and emission spectroscopy. Broad and structureless fluorescence spectra of phenyldisilanes and naphthyldisilanes with large Stokes shifts have been observed and they have been attributed to the emissions from the intramolecular charge-transfer (c.t.) states with large dipole moments. Evidence that

  The photophysical properties of two series of oligosilanes, (1-naphthyl)-(SiMe2)(n)-(1-naphthyl) (1-5) and (9-anthryl)-(SiMe2)(n)-(9-anthryl) (6-10) with n = 1-4 and 6, were investigated. In these compounds, two types of interactions, a pi-pi interaction between two aromatic groups and a sigma-pi interaction between aromatics and: a silicon chain unit, were observed. Intramolecular excimer emission was observed in cyclohexane when n greater than or equal to 2. The strongest excimer emission of 2 and 7 is different from the Hirayama rule (n = 3) proposed for carbon analogues and also shows that intramolecular cycloaddition is minor. The time-resolved fluorescence speptra of an anthryl series revealed that the time constant of excimer formation varied depending on the chain length (82-152 ps). In the cases of 4, 5, and 10, charge-transfer (CT) emission was observed in acetonitrile or THF. The time constant of the CT-state formation for 10 was relatively slow (45 ps), which may indicate a conformational change. Monomer emission from the locally excited state was observed for I and 6 in both cyclohexane and acetonitrile.
