 This article describes an summary of 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. At the point when an occasional length inside the PC structures of CLCs and CCs relates to a few hundred nanometers of the daylight frequency, the photonic band-holes (PBGs) are frequently envisioned as Bragg reflection hues. When combining fluorescence dyes within the CLCs and CCs, the stimulated laser action at PBG band edge(s) or within the PBG wavelength are often generated by optical excitation. Moreover, the optically excited laser action is controllable by external stimuli thanks to the self-organization of CLCs and CCs. This review highlights not only the research backgrounds of CLC and CC structures as PCs, but also the experimental results of their versatile soft and tunable laser applications. We believe that a good sort of CLC and CC structures will have leading roles within the next generation of optoelectronic devices of organic and polymer materials. 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 (MOFs)
