Abstract
Novel fluorescent polyhedral oligomeric silsesquioxane (POSS) colorants are provided. The colorants are strongly fluorescing and long lasting with excellent light stability. The novel colorants can be prepared from chromophores found in common pigments and provide a simple way to convert an insoluble pigment into a soluble fluorescent colorant.
