Resumen:
Porphyrins and their derivatives may find a variety of applications in
biomedical fields due to their interesting photochemical and
photophysical properties. A tetraphenylporphyrin (TPP)-based
methacrylate monomer was synthesized and subsequently copolymerized with
oligo(ethylene glycol) methacrylate to yield materials exhibiting
thermoresponsiveness in aqueous solutions. The TPP-based monomer content
ranged from ca. 1 to 6 molar percent in the copolymers. The cloud point
of the copolymers in water was found to decrease with increasing amount
of TPP content in the copolymers, ranging from 64 & DEG;C for the
oligo(ethylene glycol)-based homopolymer to 57 & DEG;C for the
copolymer with ca. 5 mol % TPP methacrylate monomer loading. Thus, the
phase transition behavior can be tuned through the variation of the
porphyrin-based monomer loading.
