Notes:
Herein, we report the fabrication of anthracene nanostructures and, in turn, their thinfilms at the air-water interface by recrystallization at the liquid-liquid interface. Thismethod is simple, inexpensive and allows the deposition of anthracenenanoparticulate thin films on large and a variety of substrates. The virgin films werecharacterized by X-ray diffraction (XRD), Scanning Electron Microscopy (SEM),Transmission Electron Microscopy (TEM), Hot Stage Polarizing Microscopy andUV-Visible spectroscopy. Interestingly, it was found that these thin films arecomprised of nanosized bushy clusters of anthracene molecules as revealed by TEM.Also, with increase in the thickness of the films, the formation of irregular microtapeswas evinced by SEM. The absorption spectra reveals the presence of 2 excitonicpeaks for the lowest dip sample (10 dips) whereas the spectra recorded for higher dipsamples (20 dips, 30dips, 40dips) closely match with that of pure anthracene inchloroform solution. The dramatic reduction in the melting point as revealed by hotstage polarizing microscopy is the salient feature of the work
