Abstract
Photoresponsive polymers that comprise a unit derived from an amide functional diol compound that includes a coumarin group are provided. Advantageously, the photoresponsive groups of the photoresponsive polymers may be used to control the viscosity of the photoresponsive polymer. The photoresponsize polymers may also include units derived from amide functional diol compounds with include a fatty acid chain or a polyethylene glycol chain. The photoresponsive polymers may be used for 3d printing. When an adhesive group is added to a photoresponsive polymer they may be used as an adhesive. Adhesive groups include catechol groups.
