A novel fluorescence sensor based on covalent immobilization of 3-amino-9-ethylcarbazole by using silver nanoparticles as bridges and carriers

Designing model imino bifunctional chelators for radiopharmaceuticals –in vitroantitumor activity, photoluminescence and structural analysis

“…54 The increased luminescence intensity and quantum yield of compound 2 relative to compound 1 must be attributed to the 3-amino-9-ethylcarbazole linked to the salicylaldehyde backbone. It is not thought that it contributes directly to the light emission (having an emission wavelength of ∼400 nm 55 ), but it may be more effective in stabilizing the entire molecule and reducing non-radiative recombination due to its large size or the carbazole group may be excited and effectively transfer energy to the salicylidene moiety.…”

Effect of Surface Plasmon Resonance in the Fluorometric Properties of Molecules and Complexes

“…Работы по применению золотых и серебряных наночастиц в качестве флуоресцирующих зондов свидетельствуют, что эффект NSET в аналитических определениях используется как в растворах, так и на поверхности различных матриц. Наночастицы серебра находят применение для ковалентного закрепления индикаторных красителей на поверхности кварцевого стекла с целью получения флуоресцентного датчика для определения рутина [4].…”

“…При этом наночастицы серебра не участвуют в переносе энергии возбуждения. Способ позволяет определить рутин в диапазоне 2.0 •10 −6 -1.5 •10 −4 М с пределом обнаружения 8.0 • 10 -7 М [4].…”

Dielectric Properties, AC Conductivity, and Electric Modulus Analysis of Bulk Ethylcarbazole‐Terphenyl

“…Poly(Ethylcarbazole) is a conducting polymer with π-conjugated structure, which has been widely studied and used in photovoltaic and electroluminescent devices due to its excellent thermal stability and electronic properties [17][18][19]. is polymer exhibits a low dielectric constant over a wide range of temperature and frequency.…”
