Novel push-pull fluorescent dyes – 7-(diethylamino)furo- and thieno[3,2-c]coumarins derivatives: structure, electronic spectra and TD-DFT study

Synthesis, FT-IR, structural, thermochemical, electronic absorption spectral, and NLO analysis of the novel 10-methoxy-10H-furo[3,2-g]chromeno[2,3-b][1,3]thiazolo[5,4-e]pyridine-2,10(3H)-dione (MFCTP): a DFT/TD-DFT study

“…Also, the structure-activity relationship (SAR) was studied for the antimicrobial application of the current compound (3,MFCTP). Mass spectrum, m/z (I r %): 340 (M + , 100), 312 (62), 296 (43), 269 (58), 191 (41), 175 (28), 169 (12), 147 (34), 123 (9), 118 (70), 107 (40), 91 (23), 77 (27), 64 (13). Anal.…”

“… 8 The optimized geometries of some furo[3,2- g ]chromenes have been examined by DFT-theoretical calculations. 9,10 Photoelectrical, photosensitivity, photovoltaic, photodiode, electronic spectra, solvatochromic computational and molecular docking studies have been performed on a range of furo[3,2- g ]chromene derivatives. 11–16 The experimental values of the molecular geometry, vibrational frequencies, atomic charges, dipole moment, thermodynamical properties, etc.…”

Synthesis and antimicrobial evaluation of the novel heteroannulated furo[3′,2′:6,7]chromeno[2,3‐b]pyridines: Part 1

“…[ 7 ] DFT‐theoretical calculations were used for inspection of the optimized geometries of some furo[3,2‐g]chromenes. [ 10–12 ] In addition, the spectral properties, photoelectrical, photosensitivity, and photodiode studies were performed for a diversity furo[3,2‐g]chromenes. [ 13–15 ] Biological activity is well known for furo[3,2‐g]chromenes such as antimicrobial, [ 16 ] anticancer, [ 17 ] antitumor, [ 18 ] anti‐HIV, [ 19 ] analgesic, and anti‐inflammatory activities.…”

A Highly Water-Soluble Fluorescent and Colorimetric pH Probe

“…On the other hand, fluorescence must be guaranteed by a suited emissive core. Heterocyclic molecules [7][8][9][10][11][12][13][14][15][16][17][18][19][20][21], as one of the most important classes of compounds, can play the role of fluorogenic moiety. At present, one of the major problems encountered in optimizing optical sensors is achieving the right balance between the presence of the fluorogenic unit (soluble in organic solvents) and the water solubility.…”
