Replacement of every other hydrogen atom in trans-polyacetylene by other atoms, such as fluorine, results in a simple linear polymer with two carbon atoms per unit cell of the polymer chain. In such polymers, dimerization can be induced or destroyed reversibly by the application of a uniaxial stress. As a consequence, the nonlinear optical properties can be switched dramatically between those of dimerized chains, which have degenerate ground states, and nondimerized chains, which have a nondegenerate ground state.
