摘要

We achieved visible-light-driven [2+2] solution polymerization of phenylenediacrylate monomers via energy transfer photocatalysis. This method yields cyclobutane-containing polymers with good thermal stability and processability

which are depolymerizable

showing potential for closed-loop recycling.

Abstract

The [2+2

]

photopolymerization of bisolefinic monomers is an important method for the synthesis of polymeric materials. However

these processes are usually carried out in solid states under the irradiation of high-energy UV light

while the corresponding [2+2

]

polymerization in solution has proved to be inefficient due to the lack of preassembly of the monomers. Herein

we demonstrate that the [2+2

]

polymerization of

-phenylenediacrylate monomers can be achieved in solution under visible light by employing energy transfer catalysis with 2

2’-methoxythioxanthone as a photocatalyst. Because no preassembly is required

this solution polymerization is applicable to

-phenylenediacrylate monomers with different ester groups

affording a series of cyclobutane-imbedded full-carbon chain polymers with high thermal stability

good solubility

and processibility. In addition

by virtue of the reversibility of the photo [2+2

]

cycloaddition

this [2+2

]

photopolymerization product can also undergo depolymerization to lower molecular weight polymers

suggesting the potential of this class of photopolymerization in the development of closed-loop chemical recyclable polymers.
