Two conjugates of tetraphenylethene (TPE) and diketopyrrolopyrrole (DPP) were synthesized and their fluorescence properties were investigated. Both DPP1 and DPP2 show intense fluorescence and large Stokes shifts in both solution and solid state. In dilute

Pathogenic bacteria and their biofilm formation are responsible for a broad spectrum of microbial infections. A novel enzyme-responsive reporter molecule (ERM-1), which can specifically recognize AmpC β-lactamase (Bla) in drug resistant bacteria, has been developed to enable the selective localization of biofilms.

Herein, we designed and synthesized a compound, Di-TPE, which has the torsional, locked stacking effect in aggregation with aggregation-induced emission properties in solution. The carbon chain of Di-TPE molecule centered on the nitrogen atom acts as a linker to connect two tetraphenylethylene groups. Di-TPE has a torsional stacking effect in the aggregation state, which is very different from the face-to-face stacking mode of TPE. Under the torsional stacking effect, Di-TPE aggregates will also form intra-locked conformation, resulting in the electron cloud distribution of Di-TPE aggregates with the sandwich biscuit shape. This is completely different from TPE and has a profound effect on the spectral properties of Di-TPE. Di-TPE with aggregation-induced emission properties under torsional stacking effect may provide a beneficial help for researchers to expand the field of fluorescent molecules, luminescent devices and biological fluorescent probes.
A ratiometric fluorescent system for carboxylesterase detection with AIE dots as FRET donors
Wu, Yinglong,Huang, Shuailing,Zeng, Fang,Wang, Jun,Yu, Changmin,Huang, Jing,Xie, Huiting,Wu, Shuizhu
, p. 12791 - 12794 (2015)
A ratiometric fluorescent system for CaE detection with AIE dots as the FRET donors was designed. Upon enzymatic reaction, electrostatic interaction between the cationic TPE-N+ dots and the enzymatic reaction product - the negatively charged fluorescein molecules - allows the FRET process to proceed, thus affording the ratiometric fluorescence CaE assay.
Intermolecular hydrogen-bond interaction to promote thermoreversible 2'-deoxyuridine-based AIE-organogels

An amphiphilic polymer bearing tetraphenylethene (TPE) moiety was synthesized by convenient reactions. The polymer exhibits unique aggregation-induced emission (AIE) characteristics and can self-assemble to size-tunable particles in DMF/water mixtures. Th

Understanding the physical mechanisms governing aggregation-induced-emission (AIE) and aggregation-caused-quenching plays a vital role in developing functional AIE materials. In this work, tetraphenylethene (TPE, a classical AIEgen) and naphthalimide (NI, a popular fluorophore with ACQ characteristics) were connected through non-conjugated linkages and conjugated linkages. We showed that the nonconjugated-linkage of TPE to NI fragments leads to substantial PET in molecular aggregates and ACQ. In contrast, the conjugated connection between TPE and NI moieties results in the AIE phenomenon by suppressing twisted intramolecular charge transfer. This work provides an important guideline for the rational design of AIE materials.
