摘要

The present investigation is focused on the macro and nanocrystals of 4-(4-chlorophenyl)-7,7-dimethyl-7,8-dihydro-4H-1-benzopyran-2,5(3H,6H)-dione (CPDMDHHBPHHD), its synthesis, and the various characterization and comparative studies performed to assess its applications. Nanocrystals were prepared by milling procedure and its evaluation and utility than macro-sized entitled crystals were thoroughly discussed. The single crystal XRD study reveals the macro-crystalline lattice parameters with the empirical formula as C_(17)H_(17)ClO_3 and a= 11.9005 A, b = 5.7971 A, c = 22.608 A and β = 93.97°. The crystal system is monoclinic with space group P2,. The nanoform of entitled crystals specimen are of 16 nm of size. Characterization studies for macro- and nano-scaling such as dielectric, fluorescence (FL), photoconductivity, tribological study, and nano influx for filters were performed and reported. From the present study, it could be concluded that CPDMDHHBPHHD crystals are known to be best for electronic filters, frequency doubling circuits, second harmonic generation (SHG) efficiency, and nano level influx value which is useful for opto-electronic applications.
