چکیده

Compounds incorporating the tetrathiafulvalene (TTF) donor unit and one or two cyanoethynylethene (CEE) acceptor units were prepared by Knoevenagel condensations of highly unstable, TTF-linked propargylic aldehyde or ketone derivatives. The resulting TTF-CEEs are very strong chromophores with low-energy end-absorptions beyond 900 nm. The molecules experience reversible oxidations of the TTF unit, and the optical properties of the oxidised species were elucidated by spectroelectrochemistry.

Triarylborane conjugated dicyanovinyl chromophores: intriguing optical properties and colorimetric anion discrimination.

Three new triarylborane conjugated dicyanovinyl chromophores (Mes2B-π-donor-DCV); donor: N-methyldiphenylamine () and triphenylamine ( and [with two BMes2 substitutions]) of type A-D-A (acceptor-donor-acceptor) are reported. Compounds exhibit intense charge transfer (CT) absorption bands in the visible region. These absorption peaks are combination CT bands of the amine donor to both the BMes2 ...

Modulation of the charge transfer and photophysical properties in non-fused tetrathiafulvalene-benzothiadiazole derivatives.

Bis(thiomethyl)- and bis(thiohexyl)-tetrathiafulvalene-bromo-benzothiadiazoles, containing electron donor tetrathiafulvalene (TTF) and electron acceptor benzothiadiazole (BTD) units, have been prepared by Stille coupling reactions between the TTF-SnMe3 precursors and BTD-Br2. In another series of experiments, TTF-acetylene-BTD compounds have been synthesized by Sonogashira coupling between eith...

Double-bond versus triple-bond bridges: does it matter for the charge-transfer absorption by donor-acceptor chromophores?

Much work has focused on elucidating the different abilities of alkene and alkyne units to transmit donor–acceptor conjugation. One approach is to compare the characteristic chargetransfer (CT) absorption band maxima. The CT band relies on both donor and acceptor strengths, that is, the energy of the separate HOMO of the donor and the separate LUMO of the acceptor, as well as on the electronic ...

Applying Density Functional Theory to Study NLO Properties of Benzyne-Based Chromophores

Density Functional Theory (DFT) calculations were employed to investigate the structural characteristics, electronic properties, and nonlinear optical properties of Benzyne-Based Chromophores at B3LYP/6-31G(d,p) level. The effects on the hyperpolarizabilities of various donor and acceptor substituent (H, F, Cl, Br, Me, NH2, OH, NH3+, COOH, CHO, CN, NO,NO2 ) were studied. The results reveale...

Self-Sorting of cyclic peptide homodimers into a heterodimeric assembly featuring an efficient photoinduced intramolecular electron-transfer process.

We describe the thermodynamic characterisation of the self-sorting process experienced by two homodimers assembled by hydrogen-bonding interactions through their cyclopeptide scaffolds and decorated with Zn-porphyrin and fullerene units into a heterodimeric assembly that contains one electron-donor (Zn–porphyrin) and one electron-acceptor group (fullerene). The fluorescence of the Zn-porphyrin ...
