“…These dyes attract have been paid much attention because of their use for determination of solvent polarity [3], as well as their potential application as colorimetric chemosensors for volatile organic compounds [4,5]. Charge transfer dyes have also been developed for use as photo-(PL) and electroluminescent (EL) materials in dye lasers [6,7], sensors [8], switchable viscosity probes [9], dual-ion-switched molecular brakes [10], dyesensitized solar cells (DSSCs) [11][12][13] and optical light emitting diodes (OLEDs) [14].…”

Novel donor-π-acceptor dyes bearing the pyrimidine unit as an electron-withdrawing group have been synthesized by using combination of two processes, based on the microwave-assisted Suzuki cross-coupling reaction and nucleophilic aromatic substitution of hydrogen. Spectral properties of the obtained dyes in six aprotic solvents of various polarities have been studied by ultraviolet-visible and fluorescence spectroscopy. In contrast to the absorption spectra, fluorescence emission spectra displayed a strong dependence from their solvent polarities. The nature of the observed long wavelength maxima has been elucidated by means of quantum chemical calculations. The electrochemical properties of these dyes have been investigated by using cyclic voltammetry, while their photovoltaic performance was evaluated by a device fabrication study. The experimental and calculation data show that all of the dyes can be regarded as potentially good photosensitizers for dye-sensitized solar cells.

“…73 One of the major drawbacks of Rhodamine-6G is its lack of photostability. 40,97 The system used for lasing performance studies of the fiber media was a frequencydoubled Quanta-Ray DCR Nd:YAG Q-switched laser with a repetition rate up to 30 Hz producing 8 ns pulses at 532 nm. The dye-doped fiber was longitudinally pumped and placed in a cavity consisting of a ~100% reflecting flat mirror (at 0°) and a ~70% reflecting flat output coupler (at 0° through the range 550-630 nm) at the two ends of the cavity.…”

“…These electron flowing effects of D-π -A charge transfer chromophoric system have also gained considerable importance from the viewpoint of their applications in optoelectronics materials [10][11][12][13][14]. There are many research activities [10][11][12][13][14][15][16] focused on the development for the power conversion efficiency, photo-stability and absorption or emission properties within their D-π -A structural systems. One of the key problems associated with the development for above mentioned application materials is to design the D-π -A structural system with high-performance properties.…”

Solvatochromic donor-π -acceptor (D-π -A) charge transfer dyes have been great attention from the viewpoint of their applicability as probes for the determination of solvent polarity and colorimetric chemosensors. In this work, novel solvatochromic fluorophore dyes based on D-π -A charge transfer system were designed and synthesized containing a strong electron-donating unit as a carbazole moiety and three different strong electronwithdrawing units. The corresponding molecular design and the optical properties of the D-π -A dyes were examined in various solutions with widely different polarity. The prepared dyes were found to exhibit a positive fluorescence solvatochromism. Furthermore, the energy properties of these dyes were also computationally optimized and calculated by computational simulation approaches using Material Studio 4.3 and electrochemical measurement.
