“…Photostability is a crucial property for fluorescence probes in bioimaging applications, especially in long-term tracking. 42 Photo-bleaching is a common problem in many organic fluorescence probes and limits the temporal monitoring of dynamic intracellular processes. To test the stability of the probes under continuous laser scanning, we performed imaging using CLSM for 40 min.…”

The integration of polymers, supramolecular macrocycles and aggregation‐induced emission (AIE) molecules provides numerous possibilities for constructing various functional supramolecular systems. Herein, we constructed supramolecular assembled systems based on discrete macrocyclic polymer hosts via the cooperation of hydra‐headed macrocycles containing two or three pillar[5]arene units (defined as P2, P3), the block polymer F127 and AIE molecules (alkyl‐cyano modified tetraphenylethene, alkyl‐triazole‐cyano modified 9,10‐distyrylanthracene, defined as TPE‐(CN)4 and DSA‐(TACN)2). Compared with the binary assembly between hydra‐headed hosts or F127 and AIE molecules, cascaded supramolecular assembly‐induced emission enhancement (SAIEE) in aqueous solution was achieved in discrete macrocyclic polymer‐based supramolecular assembled systems. Considering the cascaded SAIEE performance, we have successfully applied discrete macrocyclic polymer‐based supramolecular assembled systems to bioimaging and constructed an artificial light‐harvesting system (LHs) to explore more potential applications. The supramolecular assembly form of discrete macrocyclic polymers hosts and AIE molecules proposed in this work provides new inspiration for the construction and application of high‐performance supramolecular luminescent systems.

Design and synthesis of photostable triphenylamine based neutral AIE nano luminogens: specific and long-term tracking of mitochondria in cells

Abstract: Fluorescence bioimaging has become increasingly dependent on luminogens with aggregation-induced emission (AIE) properties since they are excellent at photostabilization, minimally photobleached, highly reliable, and superior in biocompatibility. Since mitochondria are...
