DIRE—the dye‐induced reorientation effect —occurs when the optical‐field‐induced reorientation of liquid crystals (LCs) is enhanced by dyes such as the thiophene‐based oligomer TR5 shown in the Figure. The synthesis of TR5 is described and its DIRE characterized. It is shown that TR5 provides a new way of controlling LC alignment using low‐intensity light (see also cover).
