Perylene based PET fluorescent molecular probes for pH monitoring

Naphth[1,2-d]imidazoles Bioactive from β-Lapachone: Fluorescent Probes and Cytotoxic Agents to Cancer Cells

“…The molar absorption coefficient (ε Abs ) is also an important parameter for the development of fluorescent probes. Samples prepared with naphth[1,2- d ]imidazoles IM1 – IM7 showed high ε Abs on the order of 10 3 to 10 4 M −1 cm −1 ( Table 1 ), which is consistent with the allowed transition π→π* of π-conjugated systems [ 26 , 28 , 29 , 30 ] characteristic of the imidazole nucleus [ 25 , 31 ].…”

A zeolitic imidazolate framework-90-based probe for fluorescent detection of mitochondrial hypochlorite in living cells and zebrafish

“…To date, fluorescent probe technology has been regarded as one of the most efficient tools for biological analysis due to its real-time monitoring and non-invasive features. [6][7][8][9][10] Accordingly, a large number of molecular probes have been utilized to sense ClO − primarily based on its highly oxidizing properties. However, many of them are limited by the complexity of the synthetic processes, non-specific targeting, poor water solubility, and high toxicity, which strongly hinder their application in biological systems (Table S1 †).…”

A multi-modal probe for trace water and simultaneously monitoring lipid droplets and lysosomes

“…[34][35][36][37] Fluorescence staining is an indispensable method to study biological and environmental systems. 38,39 To date, based on different response mechanisms, a large number of fluorescent probes have been designed for biological imaging and environmental monitoring, such as intramolecular charge transfer (ICT), 40 twisted intramolecular charge transfer (TICT), 41 aggregation-induced luminescence (ATE), 42,43 photoinduced electron transfer (PET), 44 etc. However, most of the probes used in the published reports for the simultaneous imaging of lipid droplets and lysosomes are based on ICT and TICT mechanisms.…”
