The measurement of microviscosity gradients across different regions self-assembled systems is crucial for optimizing their performance in both biological and industrial applications. However, this task has long been challenging due to the spatial barrier within systems, interference from polarity gradients, lack region-positioned probes. To overcome these challenges, we developed three kinds length-regulated aggregation-induced emission (AIE) probes resolution microviscosity. These AIE with varying alkyl chain lengths showed high sensitivity (0.81) over a viscosity range 2 435 mPa s unaffected luminescence environmental polarity, ensuring accurate measurements diverse environments. Using micelles as model were able localize selectively ranging hydrophobic core hydrophilic shell interface. results indicated that was highest gradually decreased toward outer regions. Furthermore, successfully applied monitoring hydrogels food thickeners, showing strong correlation among fluorescence intensity, tensile strength, thickening effects. findings underscore potential evaluating

Abnormal viscosity is closely related to the occurrence of many diseases, such as cancer. Therefore, real-time detection changes in living cells great importance. Fluorescent molecular rotors play a critical role detecting cellular viscosity. Developing red emission probes with large Stokes shifts and high sensitivity specificity remains an urgent important topic. Herein, novel viscosity-sensitive fluorescent probe (TCF-VIS1) stokes shift was prepared based on 2-dicyanomethylene-3-cyano-4,5,5-trimethyl-2,5-dihydrofuran (TCF) skeleton. Due intramolecular rotation, itself does not fluorescence at low With increase viscosity, rotation TCF-VIS1 limited, its obviously enhanced. The has advantages simple preparation, shift, good selectivity, cytotoxicity, which make it successfully used for cells. Moreover, showed potential cancer diagnosis cell level tumor-bearing mice by expected enrich strategies biological systems offer tool diagnosis.
