  potential for biological and medical applications. Herein we report the first design, synthesis, dual detection validation, and cytotoxic testing of four promising BODIPY dyes for dual 19F MRI–fluorescence detection. Using straightforward Steglich reactions, small fluorinated alcohols were easily covalently tethered to a BODIPY dye in high yields, leaving its fluorescence properties unaffected. The

  Disclosed is a process for preparing a particulate toner for developing an electrostatic image, which comprises suspending a polymerizable monomer composition comprising a polymerizable monomer, a resin dissolved therein, and a coloring agent in an aqueous medium not containing a dispersant to prepare a pre-suspension, jetting the pre-suspension through a nozzle under elevated pressure in a flowing direction which is forced to vary so that the pre-suspension collides with a predetermined plane or with each other, and then immediately passing the pre-suspension through an apparatus for throttling the path to produce back pressure and shearing stress to prepare a suspension containing a particulate polymerizable monomer and subjecting the resulting suspension to polymerization. The toner prepared by the process is a high performance toner which is free of finely divided grains and emulsion, exhibits a high chargeability, a uniform chargeability distribution, an excellent environmental stability and a high definition, and is insusceptible to fogging and unevenness.
