WebThe invention discloses a trans-dithienylethylene derivative, a preparation method and application thereof, wherein a benzene ring or a benzene ring with an alkyl chain is connected to the alpha-position of thiophene of the trans-dithienylethylene for aromatic derivation, so that the conjugation degree of the trans-dithienylethylene is improved, … WebTransient optical studies, at the nanosecond and femtosecond time scales, have been carried out on three structurally different porphyrin dyes to probe their charge transfer dynamics relevant to spectral sensitization and dye-sensitized solar cell (DSSC) operation. Two of them, showing a β substitution pattern, were previously reported: ZnB bearing an …

WebDec 25, 2008 · Fluorescence and absorption spectra and fluorescence lifetimes have been measured for alpha,omega-dithenylbutadiene (DTB) and alpha,omega-dithenylethylene (DTE) in different solvents and at different temperatures as well as in the vapor phase. It is shown that the emission of DTB consists of the S(2 … WebIn this work, we combined the phosphorescence and photochromic properties together by connect a classic photochromic dye (bithienylethene) with an efficient phosphor (thiochroman-4-one) via sp 2 and sp 3 linker (BTE1o and BTE2o). These compounds show typical photochromic phenomenon in solution and polymer matrix and have good fatigue … WebComparison of the linear and third-order nonlinear optical properties of these donor−π-acceptor chromophores shows that the elongation of the oligothiophene-based spacer or further introduction of a double bond leading to a dithienylethylene spacer produces a considerable bathochromic shift of the absorption maximum together with a dramatic ... bavaria campingplatz eging am see
