The present application discloses the first rare-earth-free metal organic framework (MOF) yellow phosphors that can be effectively excited by blue light and assembled in a white light emission (WLED) device with a blue chip. The compounds of the present invention exhibit significantly enhanced emission intensity compared to the constituent ligand and high quantum yield and high thermal and moisture stability and photoluminescence. The invention also includes light emitting devices comprising any of these MOF yellow phosphors and methods of preparing these compounds and devices.
