“…The polarization occurring upon irradiation results from the electron donor-acceptor interaction between the electron-donating substituents at the 3-position and the electron-accepting carbonyl group of the chromophorous system [19,20]. The bands of absorption and emission of the dyes largely depend on the electron donating power of the substituents at the 3-position.…”

“…According to the spectroscopic research, a significant increase in the quantum yield of fluorescence for 3‐acetamidobenzanthrone and 3‐methoxybenzanthrone going from toluene to N , N ‐dimethylformamide (about 3.5 times) is a consequence of the decrease in the polar media excited singlet electronic level and increase in triplet level; this reduces the probability of intersystem crossing process and increases the quantum yields. In contrary, at non‐polar media the intersystem crossing from the vibrational levels of S‐state occurs quite effectively, thus 3‐acetamidobenzanthrone has low emission quantum yield.…”

In the present study a new luminescent dye 3‐N‐(2‐pyrrolidinylacetamido)benzanthrone (AZR) was synthesized. Spectroscopic measurements of the novel benzanthrone 3‐aminoderivative were performed in seven organic solvents showing strong fluorescence. The capability of the prepared dye for visualization has been tested on flax, red clover and alfalfa to determinate the embryo in plant callus tissue cultures. Callus cells were stained with AZR and further analysed utilizing confocal laser scanning fluorescence microscopy. Performed experiments show high visualization effectiveness of newly synthesized fluorescent dye AZR that is efficient in fast and relatively inexpensive diagnostics of callus embryos that are problematic due to in vitro culture specificity.

“…Picture was obtained with 488 nm laser. Magnification ×200; laser power 38.9; pinhole 158.4 transfer in benzanthrone dyes occurs from the electron donor-acceptor interaction between electron-donating substituents at a C-3 position and the electron-accepting carbonyl group of the chromophoric system (Khrolova et al, 1984).…”

Benzanthrone derivates are now widely used in many industrial and scientific applications as dyes for polymers and textiles. In biochemical, biomedical and diagnostics investigations benzanthrone dyes are used as a lipophilic fluorescent probe since many benzanthrone derivates demonstrate bright fluorescence and they have ability to intercalate between membrane lipids. The aim of research presented here was to assess the luminescence ability of benzanthrone derivatives using microscopic visualization of biological objects. Accordingly, specimens of freshwater trematodes: Diplostomum spathaceum, Diplodiscus subclavatus and Prosotocus confusus, were stained by novel benzanthrone dyes using different fixatives. The samples were examined under a confocal laser scanning microscope. All of the dyes tested demonstrated good results for digestive and reproductive system visualization. Based on obtained results we conclude that benzanthrone dyes could be used for internal and external structure confocal laser scanning microscopic imaging of trematode specimens.
