An amphiphilic maltoheptaose-tetraphenylethylene (Mal-TPE) conjugate can assemble in an aqueous medium and the aggregates exhibit an aggregation-induced emission (AIE) effect. The sizes of Mal-TPE aggregates decrease with the increase in temperature, resulting in temperature-dependent fluorescence properties.

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.

Abstract: Luminescent organic nanoassemblies have received great attention in recent years due to their potential applications in material science and bioimaging. Since most of the fluorophores undergo aggregation-caused quenching in the solid state, thei

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.

Real-time monitoring of cell apoptosis could provide valuable insights into early detection of therapy efficiency and evaluation of disease progression. In this work, we designed and synthesized a new live-cell-permeable, fluorescent light-up probe for real-time cell apoptosis imaging. The probe is comprised of a hydrophilic caspase-specific Asp-Glu-Val-Asp (DEVD) peptide and a hydrophobic tetraphenylethene (TPE) unit, a typical fluorogen with aggregation-induced emission characteristics. In aqueous solution, the probe is almost nonfluorescent but displays significant fluorescence enhancement in response to caspase-3/-7, which are activated in the apoptotic process and able to cleave the DEVD moieties. This fluorescence "turn-on" response is ascribed to aggregation of cleaved hydrophobic TPE residues, which restricts the intramolecular rotations of TPE phenyl rings and populates the radiative decay channels. The light-up nature of the probe allows real-time monitoring of caspase-3/-7 activities both in solutions and in living cells with a high signal-to-noise ratio. The probe provides a new opportunity to screen enzyme inhibitors and evaluate the apoptosis-associated drug efficacy.
