Abstract: Fluorescent bioprobes are powerful tools for analytical sensing and optical imaging, which allow direct visualization of biological analytes at the molecular level and offer useful insights into complex biological structures and processes. The sensing and imaging sensitivity of a bioprobe is determined by the brightness and contrast of its fluorescence before and after analyte binding. Emission from a fluorophore is often quenched at high concentration or in aggregate state, which is notoriously known as conce… Show more

“…TPE‐based dyes have received much attention because of their relatively easy synthesis and because they are prone to further functionalization 18, 19, 20. Several TPE‐based fluorescent probes for the detection of bovine serum albumin (BSA) have been designed by Tang and co‐workers 20.…”

“…TPE‐based dyes are barely fluorescent in their separated monomer forms but highly emissive upon aggregation because of the restriction of intramolecular rotations 18, 19, 20. We expect that, when the intramolecular rotation of the TPE group is restricted, the nonradiative pathway of the TPE triplets is blocked and that the energy would transfer to the metal center (Scheme 1).…”

“…Aggregation is therefore the key of "photo-switching" in the on-off luminescent states. With this regard, the first rhodamine-based luminogen of bisbenzofuran-bisbenzopyrano-xanthene derivative [16] with AIE [17][18][19][20][21][22][23] properties was developed since its inherent rhodamine units can be easily in the confined, aggregated state.…”

“…Several traditional sensing methods have been established to detect gas, such as catalytic, thermal, semiconductors, and surface acoustic wave, infrared spectroscopic, electrochemical and gas chromatographymass spectrometric (GC-MS) techniques [14][15][16]. Most of those conventional methods have complex and costly instrumentation and invariably need a long analysis time.…”
