NOVELTY - An olefin-containing compound (1 or 2) having alkyne group, is new.    USE - Novel olefin-containing compound used as electronic material and photochromic material (both claimed). Uses include but are not limited to luminescent material, pigment for dye-sensitized solar cell, light-emitting element, photochromic ink, goggles, decoration material, optical memory, coloring agent, foundation, light control type photonic crystal and optical switch.    ADVANTAGE - The olefin-containing compound which strongly absorbs ultraviolet visible light of broad wavelength and has excellent charge transport characteristics is manufactured efficiently.    DETAILED DESCRIPTION - An olefin-containing compound of formula (1 or 2) having alkyne group, is new.
