    Abstract: A homopolymer formed from monomers which contain groupings which are at least trinuclear, which are capable of absorbing the electromagnetic radiation of visible light, and which are structured so that in their thermodynamically stable state they are distended and strongly anisometric, is disclosed. The trinuclear groups of the homopolymer include at least one electron-attracting substituent which gives rise to a dipole moment which forms an angle of at least 20° with the longitudinal axis of the trinuclear groups. The homopolymer contains covalently bonded side groups branching from the backbone represented by the following formula, —§—T—Q—E. In the formula: § represents one of oxygen, sulphur and NR1; T represents a (CH2)n radical, optionally interrupted by, for example, —O—; Q represents a divalent linking group; and E represents the trinuclear group, e.g., represented by the following formula (VII),
