“…Increasing the speed of the glass roller to 30 mm/min provided well-ordered alignment of microdomes with a uniform dome diameter for each complex. A similar effect of the speed was already observed for polymer solutions [14]. The drastic difference in sample morphology can be explained by looking at the dewetting mechanism.…”

“…On the other hand, a patterned substrate is very effective to selectively and precisely control the position and location for encapsulated organic NCs so as to assemble and integrate an ordered array structure. 127,128 So far, sedimentation method under gravity effect, 129 crystallization induced by capillary force, 130 and dewetting process 131 are well known to fabricate self-assembled micro-and nanostructure on a flat substrate for photonic device applications using polymer microspheres (or polymer colloidal particles) and colloidal silica particles. 123 However, these techniques cannot be unexpected to produce an ordered array structure for organic NCs.…”

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.

“…Stripe-and dot-shaped polymeric patterns in micro-or submicrometer scale are obtained by dewetting of a thin film of a polymer solution on a flat substrate [4], and the patterns are known to depend on both the concentration of polymer and the dewetting velocity [21,22]. Similarly, periodic stripes of nanoparticles are recorded by dewetting of a thin film of a nanoparticle solution [23,24].…”
