A light emitting device is disclosed having a light emitting layer containing a porphyrin derivative compound each pyrrole group of which is characterized by having a straight-chain or branched side-chain alkyl group having 5 to 20 carbon atoms, and the central metal of which is Cr, Ni, Cu, Co, Ru, Rh, Pd, Ir, Pt or Au. The compound is light-emissive and especially has phosphorescent light emission properties and liquid crystal properties. Also disclosed is a display unit using the light emitting device.

Pyrroles substituted with long alkoxy groups are prepared by the reaction of iminodiacetic acid dimethyl ester and dimethyl oxalate and the subsequent alkylation. These pyrroles are good precursor molecules for the corresponding porphyrins, which are expected to form an ordered columnar mesophase and are able to co-ordinate to various metals.

Aliphatic derivatives of hydrazinophyrin, a new type of tetrapyrrolic macrocycle prepared by the condensation of 2,5-diformylpyrroles with hydrazine, exhibit liquid crystalline properties as judged from polarising optical microscopy; these hydrazinophyrins appear to be the first mesogens derived from an expandedporphyrin core.
developed by Merz et al. We show that the alkyl chain length has a huge influence on the polymer solubility and as a consequence on the surface morphology and hydrophobicity. Moreover, the alkyl chain length should be at least greater than eight carbons in order to obtain parahydrophobic properties. The properties are also controlled by the electrolyte nature. These materials can be used for many potential
