NOVELTY - An amine compound (I) is new.    USE - New amine compound is used as functionalized carbon matrix used for nanomaterial, compound, composition and composite material (all claimed). Uses include but are not limited to electronics, biomedical imaging, catalyst for catalyzing reaction of biological feedstock, high-frequency electromagnetic absorber, contrast agent for biomedical imaging, high-frequency electromagnetic absorber, magnetic-fluid hyperthermia cancer therapy, polymer electrolyte fuel cell, anode in lithium-ion battery and capacitor.    ADVANTAGE - The functionalized carbon matrix has high thermal stability, and can allow functional groups e.g. acidic or basic groups, to remain effective at higher temperatures and in more extreme conditions, thereby allowing more effective catalysis reaction, by economical process. The composite material has excellent resistant to hydrothermal degradation and high catalytic activity.    DETAILED DESCRIPTION - An amine compound of formula (I) is new.
