摘要：NOVELTY - A dithiophene ethylene compound containing 2,1,3-diazosulfide unit, is new. USE - The dithiophene ethylene compound containing 2,1,3-diazosulfide unit is useful for storing high thick photons and preparing erasable light storing material and material of light-operated switch. ADVANTAGE - The dithiophene ethylene compound containing 2,1,3-diazosulfide unit has fine photochromism; where it is capable of circularly changing between the colorless and red under irradiating by ultraviolet light. Moreover, the fluorescence of photochromism mother body is very strong; the fluorescence is badly quenched after being carried out ring-closing reaction; and the fluorescence is decreased to 10% of the ring-closing body. DETAILED DESCRIPTION - A dithiophene ethylene compound containing 2,1,3-diazosulfide unit of Formula I, is new. R1, R2, R5, and R6 = H, 1-12C alkyl, 5-6-member univalent aromatic group, 5-6-member univalent aryl heterocyclic group, substituted 5-6-member univalent aromatic group, or substituted 5-6-member univalent aryl heterocyclic group; R3 and R4 = 1-12C alkyl or 1-12C alkoxyl; where the substituents of the substituted 5-6-member univalent or bivalent aromatic group, or substituted 5-6-member univalent or bivalent aryl heterocyclic group are respectively halogen, 1-6C alkyl, 1-6C alkoxyl, nitro, or -NR8R9; and R8 and R9 = H or 1-6C chain alkyl; where the hetero atoms of the univalent or bivalent aryl heterocyclic group are respectively N, S, or O.
