Synthesis, crystal structure and photochromism of a novel spiro[indoline–naphthaline]oxazine derivative

Synthesis and Crystal Structures of Two New Oxaspirocyclic Compounds

“…In recent years, many efforts have been devoted to the preparation and characterization of spiro compounds due to diverse industrial and biomedical applications in medicine [1][2][3], catalysis [4], 18F-radiolabeling [5] and optical material [6][7][8]. The asymmetric characteristic of the molecules, owing to the chiral spiro carbon, is one of the important criteria of the biological activities.…”

Fabrication and Characterization of Bifacial Dye‐Sensitized Solar Cells Utilizing Indoline Dye with Iodine‐ and Cobalt‐Based Redox Electrolytes

“…The role of the long alkyl chain is to passivate the TiO 2 surface so that the electrons are screened from reaching the oxidized cobalt ions, thus suppressing the back electron transfer by charge recombination. [32][33][34][35]…”

The crystal structure of 1,5-di(naphthalen-2-yl)-3-(pyridin-2-yl)pentane-1,5-dione, C30H23NO2

“…With the advantages of unique pharmacological activity [4,5], high catalytic activity [6], photoelectric properties [7], biological activity [8], simple operation and low cost, pyridine derivatives were widely used in the areas of pharmacy and chemical industry [9,10]. Obviously, the synthesis of new pyridine derivatives have drawn attentions in recent decades.…”
