Polysiloxane-Based Two-Photon Fluorescent Elastomers with Superior Mechanical and Self-healing Properties and Their Application in Bioimaging

Abstract

Two-photon fluorescent polysiloxane-based elastomers with superior self-healing property were reported for the first time. Benzoxazine-incorporated polysiloxane (P1) has been successfully synthesized via “one-pot” Mannich reaction. Unlike the typical method for fabrication benzoxazine-functionalized polysiloxanes (PDMS), benzoxazine could directly attach to the main chains of PDMS without any use of heavy metal catalysts. After thermal treatment, benzoxazine ring undergo a ring-opening process and cross-linked sites built up. Finally, novel polysiloxane-based elastomers with dynamic dual cross-linked network were obtained (Cns). Cns showed excellent self-healing property. Unique two-photon fluorescent property of Cns was detected for the first time. Moreover, C3 was selected to act as cell adhesives and exhibited fine cytocompatibility. This report represented the first example about self-healing materials with potential application in bioscience and will bring new insight to self-healing materials.
