An A-D-A type of thiophene derivative with morphology-determining luminescent performance: Synthesis and application in a light emitting device

Structural origins of carbon quantum dot luminescence by synchrotron x-ray spectroscopy

“…Thiophene's planar aromatic nature and singly-bonded constituents allows RIM from π-stacking interactions and the enantiotropic mesomorphism mentioned previously [25,[37][38][39][40][41][42][43][44][45][46]. In general, thiophene is proven to act as a donor for a fluorescent charge transfer state in many AIE-active luminophores, but never for CQDs or any materials [40,41,45]. Additionally, in the three cases just mentioned, the acceptor in the fluorescent charge transfer was a conjugated aromatic system where two of the systems had nitrogen doping in this acceptor.…”

“…Some studies have reported using thiophene as a building block for AIE-active luminophores in small molecules, but not in materials. Thiophene's planar aromatic nature and singly-bonded constituents allows RIM from π-stacking interactions and the enantiotropic mesomorphism mentioned previously [25,[37][38][39][40][41][42][43][44][45][46].

Photoinduced modulation of refractive index in Langmuir-Blodgett films of azo-based H-shaped liquid crystal molecules

“…The liquid crystals molecules possessing azo-group are very interesting as morphology of the molecules can be changed under the influence of EM waves leading to changes in the bulk liquid crystalline phases. Two-dimensionally confined monolayers are good candidates for the development of next-generation flexible and transparent optoelectronics devices [15][16][17][18]. Due to enhanced physicochemical properties of the ultrathin films, its activity is extremely high as compared to the thick layers or bulk materials.…”
