The nanocrystals based on a polar organic compound INBP (4-iodo-4′-nitrobiphenyl) have been fabricated by reprecipitation approach. For the formation of INBP based nanocrystals, the intermolecular iodo⋯nitro interaction is the dominant driving force and the micelles formed by the surfactant CTAB (cetyltrimethylammonium bromide) molecules are the efficient templates for controlling morphologies of nanocrystals. The field emission scanning electro microscope (FESEM) images demonstrated that prism-like and needle-like nanocrystals of INBP were formed in pure water and micell containing aqueous solution, respectively. XRD pattern and UV/vis absorption spectra were employed to characterize the nanocrystals.
