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 کاملAggregation-induced emission-fluorophores and applications.
Aggregation-induced emission (AIE) is a novel photophysical phenomenon found in a group of luminogens that are not fluorescent in solution but are highly emissive in the aggregate or solid state. Since the first publication of AIE luminogens in 2001, AIE has become a hot research area in which the number of research papers regarding new AIE molecules and their applications has been increasing i...
متن کاملUtilising tetraphenylethene as a dual activator for intramolecular charge transfer and aggregation induced emission.
We report a simple design and synthesis of a donor-acceptor tetraphenylethene-naphthalimide (TPE-NI) dyad, in which TPE acts both as an electron-donor for intramolecular charge transfer (ICT) and activator for aggregation induced emission (AIE). Strong solvent-dependent photoluminescence covering almost the whole visible spectrum and AIE in its nanoparticle state compared to its solution state ...
متن کاملAggregation-induced emission behavior of a pH-controlled molecular shuttle based on a tetraphenylethene moiety.
Tetraphenylethene (TPE) with aggregation-induced emission (AIE) behavior as a popular backbone is applied widely in the construction of functional supramolecular systems. In this work, a TPE-based linear molecule having amide and amine units is synthesized. Its ammonium template is used to construct the N-hetero crown ether-based [2]rotaxane by the template-directed clipping approach. Their str...
متن کاملTetraphenylethene modified β-ketoiminate boron complexes bearing aggregation-induced emission and mechanofluorochromism
Two new tetraphenylethene modified b-ketoiminate boron complexes (TTPE-H and TTPE-CN) have been rationally designed and successfully synthesized. The two D–p–A type compounds exhibit typical twisted intramolecular charge-transfer (TICT) emission and evident aggregation-induced emission (AIE) characteristics, remarkable luminescence mechanochromism, and high solid state efficiency (up to 0.785 a...
