  • HYDROPORPHYRIN-DOPED NEAR-INFRARED-EMITTING POLYMER DOTS FOR CELLULAR FLUORESCENCE IMAGING
    Publication number: 20240148910
    Abstract: The present invention relates to nanoscale polymer dots (Pdots) that include strongly light absorbing semiconducting polymer nanoparticles doped with near-IR emitting dyes. The polymer functions as an antenna and transfers the excitation energy to the doped near-IR emitting dye molecules, which function as the emitting entity. The resulting Pdots feature very bright near-IR emission with emission wavelength tunability, high water solubility, and stability in biological solutions.

  • Method of making porphyrins
    Patent number: 7964720
    Abstract: A method of making a compound of Formula I: is carried out by condensing a pair of compounds of Formula II (which pair may be the same or different), or by condensing a compound of Formula III with a compound Formula IV, to produce a compound of Formula I. The condensing step may be carried out with a metal salt under basic conditions.

  • Boron complexation strategy for use in manipulating 1-acyldipyrromethanes
    Patent number: 7595407
    Abstract: A method of making a metal complex comprises combining a 1-monoacyldipyrromethane with a compound of the formula R1R2MX, wherein M is boron, R1 and R2 are each independently organic substituents; and X is an anion leaving group; to produce a metal complex of the formula DMR1R2 wherein DH is a 1-monoacyldipyrromethane. The methods and complexes are useful for the purification and synthesis of dipyrromethanes and porphyrins.
