N-type pyrazine and triazole-based luminogens with aggregation-enhanced emission characteristics.
نویسندگان
چکیده
N-type pyrazine-based 1,4- and 1,5-disubstituted 1,2,3-triazole derivatives, showing unique aggregation-enhanced emission characteristics, were facilely prepared via Cu- and Ru-catalysed azide-alkyne cycloadditions, respectively. Thanks to their electron-deficient properties, they could readily form red-emissive charge transfer complexes with electron-donating triphenylamine in the aggregate and solid states.

Aggregation-enhanced emission and efficient electroluminescence of tetraphenylethene-cored luminogens.
A new design of luminescent materials by decorating a tetraphenylethene core with four aromatic chromophores is proposed. The generated luminogens exhibit aggregation-enhanced emission and excellent solid-state fluorescence efficiency (93-99%). Efficient non-doped OLEDs based on them afford remarkable efficiencies up to 11 cd A(-1).
متن کاملFrom tetraphenylethene to tetranaphthylethene: structural evolution in AIE luminogen continues.
Replacement of phenyl ring(s) in tetraphenylethene by naphthalene ring(s) generates a series of new luminogens with aggregation-induced emission (AIE) characteristics, demonstrating that bulky naphthalene rings can serve as a rotor to construct AIE luminogens.
متن کاملTetraphenylpyrimidine-Based AIEgens: Facile Preparation, Theoretical Investigation and Practical Application.
Aggregation-induced emission (AIE) has become a hot research area and tremendous amounts of AIE-active luminogens (AIEgens) have been generated. To further promote the development of AIE, new AIEgens are highly desirable. Herein, new AIEgens based on tetraphenylpyrimidine (TPPM) are rationally designed according to the AIE mechanism of restriction of intramolecular motion, and facilely prepared...
متن کاملBiosensing by luminogens with aggregation-induced emission characteristics.
Fluorescent biosensors are powerful analytical tools for studying biological events in living systems. Luminescent materials with aggregation-induced emission (AIE) attributes have attracted much research interest and have been identified as a novel class of luminogens to develop fluorescent turn-on biosensors with superior sensitivity. In this Tutorial Review, we present an overview of the AIE...
متن کاملA probe with aggregation induced emission characteristics for screening of iodide.
The dilution controlled aggregation enhanced emission of spherically aggregated form of a triazole based probe dies down upon detecting iodide over other inorganic anions. The sensing is realised as a dynamic quenching mechanism dominated event. Being highly selective for iodide, the probe finds application in the detection of iodide in human urine.
