Growth and Characterization of Organic Based Marine Dye NLO Material: 7‐Bromo‐6‐chloro‐3‐[3‐[(2R, 3S)‐3‐hydroxy‐2‐piperidyl]‐2‐oxopropyl]‐4(3H)‐quinazolinone

Abstract

An organic marine dye compound (7-bromo-6-chloro-3-[3-[(2R, 3S)-3-hydroxy-2-piperidyl]-2-oxopropyl]-4(3H)-quinazolinone) was synthesized. The characteristics of this dye is soluble in water. The organic compound was made into a crystal by slow evaporation technique. The grown crystals were characterized by single crystal x-ray diffraction (XRD) analysis, FTIR studies and UV-visible transmittance studies and the NLO activity of the grown crystal has been checked by second harmonic generation (SHG) test.

Spectroscopic Studies of Photochemical Transformations of Cymantrenylquinazolinone Derivatives

“…In the last decades, compounds with photochromic properties have attracted considerable attention for the creation of devices for the registration and storage of optical information, molecular switches, chemical sensors, and reagents for fluorescence spectroscopy , . It is known that 2‐aryl(hetaryl)‐ and 2‐styrylquinazolinones show distinctive fluorescence properties and therefore have potential for the creation of non‐linear optical generators . Variation of the structures, namely, the substituents in the heterocyclic and aryl fragments, allows one to obtain optical systems with various spectral parameters .…”
