Systematic designed experiments were employed to find the optimum conditions for extraction of direct, reactive, and vat dyes from cotton fibers prior to forensic characterization. Automated microextractions were coupled with measurements of extraction efficiencies on a microplate reader UV-visible spectrophotometer to enable rapid screening of extraction efficiency as a function of solvent com...

The synthesis of light-harvesting arrays requires modular pigment building blocks. Boron-dipyrromethene dyes are well-suited for the photochemical sensitization of free base or metalloporphyrins. Direct access to borondipyrromethene dyes bearing reactive substituents is provided by a simple synthetic route involving two one-flask reactions. Reaction of pyrrole or 2-methylpyrrole with an aldehyd...
