Siloxane-modified porphyrin derivatives were fabricated using the Piers-Rubinsztajn reaction to improve the solubility of porphyrins in polysiloxanes. The solubility of the derivatives could be controlled by adjusting the siloxane chain length. The resulting silicone-modified porphyrin derivatives were doped into silicone elastomer prepolymer to obtain luminescent elastomers with good transparency and interfacial stability. The thermal stability and mechanical properties were well preserved compared with the original elastomer. Moreover, the organosilicon elastomer doped with porphyrin exhibited good processability and plasticity, allowing for fabrication of various complex three-dimensional models.
In this work, in order to improve the low solubility and expand the applications of porphyrins in polysiloxanes, a series of designed siloxane-modified porphyrin derivatives was fabricated based on the Piers-Rubinsztajn reaction. The solubility of the porphyrin derivatives in polysiloxanes could be controlled by adjusting the siloxane chain length. Furthermore, the silicone-modified porphyrin derivatives were doped into a silicone elastomer prepolymer to obtain luminescent elastomers, which also showed good transparency and interfacial stability. In addition, the thermal stability and mechanical properties were well preserved compared with the original elastomer. Finally, based on the above-mentioned properties, an organosilicon elastomer doped with porphyrin showed good processability and plasticity, and could be fabricated into various complex three-dimensional models.
