NOVELTY - A crystalline material contains inclusion complex containing pigment having ( pi )-plane as guest molecule, and cyclodextrin or its derivative as host molecule, and has crystal structure arranged without guest pigment molecule association.    USE - Crystalline material is used for optical material, photoelectric chemical material and electrochemical material (all claimed) e.g. field emission transistor element and organic electroluminescent element. Uses include but are not limited to polarized light material, luminescent material, circular-polarized luminescent material, electrochemical material, organic pigment solar cell, and organic electroluminescent photoelectric chemical material.    ADVANTAGE - The crystalline material is economical, and can be manufactured by simple method.    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following:    (1) manufacture of crystalline material. An aqueous solution of inclusion complex containing guest pigment molecule and host molecular is prepared. The obtained aqueous solution is maintained at 100 degrees C or less, and crystallized to obtain crystalline material. The aqueous solution of insulation complex is obtained by dissolving guest pigment molecular in aqueous acid, and making the aqueous solution into neutrality or weak base property under coexistence of host molecule, dissolving guest pigment molecule in basic aqueous solution after maintaining in neutral or weakly acidic condition, dissolving guest pigment molecule in water, adding salt under coexistence of host molecule with respect to guest pigment molecule;    (2) optical material, which contains crystalline material having luminescent property with respect to polarized light, light emission, linearly polarized light, and/or circular-polarized light;    (3) electrochemical material, which contains crystalline material having electric charge or hole transport ability, and/or oxidation reduction characteristics; and    (4) photoelectric chemical material, which comprises crystalline material having charge separation and/or light energy collection ability.
