1 Introduction Scaffolds have been extensively used in tissue engineering and regenerative medicine as a structural support, a guide for tissue in-growth, and notably, in recent years, a bioactive platform interacting with the extracellular matrix and surrounding tissues to promote tissue regeneration.[1] As tissue regeneration proceeds, there is a need for implanted non-biodegradable scaffolds to be removed.

Abstract A new class of polyphosphazene elastomers has been synthesized that combines a −P═N– backbone with both 2,2,2-trifluoroethoxy and tetraphenylethyleneoxy (TPEO) side groups. The polymer syntheses and photoproperties were first modeled using small molecule cyclic phosphazenes, and these were then applied to the high polymers. The TPEO groups confer useful mechanical and photophysical properties on the polymers.
