Modulating aggregation-induced emission via a non-conjugated linkage of fluorophores to tetraphenylethenes
A fluorophore consisting of two fluorescent moieties could display unusual optical behaviors that are unattainable in a single-fluorophore compound. Herein we reported two ‘‘dual-fluorophore’’ dyes: DNSlinked tetraphenylethene demonstrates bright aggregation-induced emission, while NBD-linked tetraphenylethene exhibits aggregationcaused quenching. Our results have important implications for eng...
متن کاملLocking the phenyl rings of tetraphenylethene step by step: understanding the mechanism of aggregation-induced emission.
Stepwise locking of phenyl rings of tetraphenylethene increases the emission efficiency of luminogen solutions gradually, thus verifying the restriction of intramolecular rotation (RIR) mechanism of the aggregation induced emission phenomenon. The emission of the luminogen with one "O" bridge could be tuned reversibly in solid state through repeated heating and grinding.
متن کاملAggregation-induced emission of siloles
Aggregation-induced emission (AIE) is a unique and significant photophysical phenomenon that differs greatly from the commonly acknowledged aggregation-caused emission quenching observed for many π-conjugated planar chromophores. The mechanistic decipherment of the AIE phenomenon is of high importance for the advance of new AIE systems and exploitation of their potential applications. Propeller...
متن کاملA general route to make non-conjugated linear polymers luminescent.
Photoluminescent polymer dots (PDs) were prepared by a moderate hydrothermal treatment of poly(vinyl alcohol) (PVA). A single excited state was established in the PL mechanism by ultrafast spectroscopy. Moreover, the applied method be used to prepare fluorescent polymer dots from other non-conjugated polymers, and shows general universality.
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...
