Title:
PORPHYRIN COMPOUND
Document Type and Number:
Japanese Patent JPH04257586
Kind Code:
A
Abstract:

PURPOSE: To obtain a porphyrin compound having an absorption spectral range corresponding to the spectral range of light rays released from a semiconductor laser, and improved in optical, chemical and electrically conductive characteristics.

CONSTITUTION: Lithium-tetra-naphthoporphyrazin free radical compound shown by formula I and dilithium-tetra-naphthoporphyrazin compound shown by formula II. Both of these compounds absorb rays at ≥750nm wavelength and are soluble in a polar organic solvent. The dilithium-tetra-naphthoporphyrazin free radical compound is usable for producing a tetra-naphthoporphyrazin compound having the other metal and the lithium-tetra-naphthoporphyrazin free radical compound is a new true molecular semiconductor.
