Self-assembly of nanoparticles is an efficient route to fabricating materials with uniform structures. Many studies so far have reported the synthesis of polymeric and metal-based particles that spontaneously self-assemble into ordered 3D superstructures. the present project is that the first to figure with hybrid metal-organic particles, adding a replacement family to the list of compounds which will be synthesised for 3D self-assembly: metal-organic frameworks. Recent developments in fabrication and uses of self-assembled photonic crystals (PCs) of organic and polymer materials, like chiral liquid crystals (CLCs) and colloidal crystals (CCs), for laser applications. Both CLCs and CCs have intrinsic capabilities to spontaneously assemble 1D-PC and 3D-PC structures, respectively. Photonic calculations show that these chiral structures can have large complete photonic band gaps. additionally , within the self-assembled chiral square crystal, we also find dual polarization band gaps that selectively forbid the propagation of circularly polarized light of a selected handedness along the helical axis direction. The self-assembly process in our proposed system is strong , suggesting possibilities of using chiral colloids to assemble photonic metamaterials. If they're describing experiments or calculations, they have to provide enough details that an independent researcher could repeat the experiment or calculation to verify the results. it's introduction and presentation for scrutiny of latest research, and therefore the critique of existing research articles.
