Fig. 1: Properties of AZ-APCs.
From: Unusual photo-tunable mechanical transformation of azobenzene terminated aliphatic polycarbonate

a Structural transformation upon photoisomerization b Molecular weights and their distributions. c An illustrative diagram of the potential energy between the cis-AZ-rich plastics and the trans-AZ-rich elastomer. Thereby achieving a photoinduced reversible transition between plasticity and elasticity to yield a flexible molding.
