Organic nanocrystals (NCs) are in the mesoscopic phase between a single molecule and the corresponding bulk crystals, and are expected to exhibit peculiar optical properties, depending on crystal size and shape. In the present Award Accounts, recent progress on hybridized organic NCs and ordered array structure of encapsulated organic NCs will be introduced in detail for optically functional materials toward next-generation organic device application. Hybrid material (or hybridization) is an important area in current material science. Our attention is now focused on coreshell type hybridized organic NCs, which seem to be the best suited nanostructure for providing novel optoelectronic properties and photonic function induced by coreshell interface interaction. On the other hand, it may be necessary to arrange and integrate organic NCs, including hybridized materials, on a substrate so as to receive and transmit input and output signals by electronically and/or optically accessing organic devices. Hence, encapsulations of organic NCs, patterned substrates, and tapered cell method have been employed suitably to fabricate and control ordered array structure of organic NCs on a substrate. Finally, the future scope in the relevant fields of optoelectronics and photonics will be discussed in brief.

“…The electronic and optical properties of organic molecular crystals are fundamentally different from those of inorganic metals or semiconductors due to the presence of weak intermolecular interaction forces (van der Waals type) [44]. For example, in organic nanoparticles studies, the size dependent fluorescent properties of perylene, pyrazoline and phthalocyanine have been established [45][46][47]. Thus the electronic/optical behaviors of ONPs are expected to be interesting because of their variability and flexibility.…”

“…The compound was dissolved in a hydrophilic organic solvent, and this concentrated solution was poured into a large volume of water, which acted as a counter solvent for the target compound. Precipitation occurs, which can lead to microcrystal dispersion . It has been shown that several factors influence the size and morphology of the microcrystals …”

Photoluminescence properties in solid state and its relationship with structural features of prop-2-enenitrile derivatives containing any of functional groups 4-halogenphenyl, phenyl, 4-dimethylamino, or 4-diphenylamino are investigated. The compounds show change in color from yellow to orange after treatment with dimethyl sulfoxide or dimethyl formamide. Nevertheless, the single-crystal X-ray diffraction for both, the original yellow and the treated orange crystals, does not display any major structural differences. The optical properties are related to the crystal packing and intermolecular interactions such as edge-to-face through the vertices of aromatic rings. The last is supported by the behavior of the presence of functional group. The absorption spectrum in solution for all compounds shows two absorption bands with wavelength of maximum absorption around 390-430 nm and at 290-300 nm. Regardless of the crystal type, the maximum emission in solution was between 450-570 nm. In solid state, yellow crystals exhibit an emission in the 500-530 nm range and in the 580-630 nm range for orange crystals. Results suggest that optical properties are strongly dependent on morphology and habit. Powder X-ray characterization shows a preferential orientation for orange crystals. All compounds are characterized by common spectroscopy techniques, fluorescence, atomic force microscopy and X-ray diffraction.
