Abstract

9‐Nitroanthracene reactant: Twenty grams (0.112 mole) of finely powdered anthracene product: 9‐nitroanthracene

Maintaining of the Green Fluorescence Emission of 9-Aminoanthracene for Bioimaging Applications

“…HCl in acetic acid under thermal conditions. 10,11 A solution of 9AA in CHCl 3 was treated with conc. HCl at 0 °C to give 9-anthrylammonium chloride ( 9AAH + ·Cl – ) as a pale red solid in 84% yield (Scheme 1).…”

“…9AA was obtained in 69% yield with >99% purity by reduction of 9-nitroanthracene 1 , which was prepared in two steps from anthracene via 9-chloro-10-nitro-9,10-dihydroanthracene, with a slurry of SnCl 2 and conc. HCl in acetic acid under thermal conditions. , A solution of 9AA in CHCl 3 was treated with conc. HCl at 0 °C to give 9-anthrylammonium chloride ( 9AAH + ·Cl – ) as a pale red solid in 84% yield (Scheme ).…”

“…Histological observations were performed using fluorescence microscopy (BX53F; Olympus Co.) equipped with a camera (Penguin 50 CL; Pixera Co.). 9-Nitroanthracene 1 , 9AA , and AQNH were synthesized according to previous reports. ,, DMSO, MeOH, CHCl 3 , HCl, HNO 3 , AcOH, anthracene, AQ , lithium aluminum hydride, lauric acid, tetradecanol, laurylamine, glucose, and Ph 3 P were purchased from Wako Co., Ltd. and Tokyo Chemical Industry Co., Ltd. in Japan. BSA, histone, and casein were purchased from Sigma-Aldrich.…”

Anthracene Based Colorimetric Molecular Sensors

“…In 1951 a similar procedure was published which already described the interstage product 9. [88] Scheme 2-11: Synthesis of 10 starting with a nitration to 9 and subsequent hydrochloric acid removal. [87] This nitration reaction of anthracene takes place in glacial acetic acid after addition of concentrated nitric acid at room temperature (Scheme 2-11).…”

“…The presence of 9 as an interstage product in the synthesis of 10 has been known for many decades [88] but was not investigated via X-ray diffraction in previous works.…”
