Capsule particles are widely used for various industrial applications. The interfacial photo-cross-linking of spherical polymer is a facile and safe approach preparing capsule particles. However, only ultraviolet light (e.g., λ = 265 nm) the because cinnamate group has been as reactive group. In this study, we synthesize derivatives 2-cinnamoylethyl methacrylate (CEMA) by introducing different substituents (o-nitro, m-nitro, p-nitro, p-dimethylamino groups) to regulate absorption wavelength photoreactive monomers. Using polymers comprising p-nitro-substituted CEMA, reaction proceeds with 365 nm LED light. Furthermore, p-dimethylamino-substituted CEMA 465 visible source. Moreover, prepared hollow show fluorescence property. Finally, demonstrated wavelength-controlled selective particle mixture groups. successfully performed
