【摘要】 <正> 有色化合物中,包括下列一种結構类型的化合物:其中B为吸电子基团,如—NO₂,>C=O…等;K为共軛体系,如—C₆H₄—等;Q为連接二个共軛体系的基团,可以是使BK与AK共軛的—CH=N—,—N=N—也可以是不使BK与AK共軛的—CONH—,—CH₂—NH—,—CH₂CONH—…等;A为給电子基团,如—OCH₃,—NH₂等。發現当Q为—CONH—,更多还原

【Abstract】 A type of organic coloring compounds can be represented as:B—K—Q—K—A in which B and A are electro - acceptor （—NO₂,>C=O,…） and electro-donor （—OCH₃, —NH₂…） respectively: K is a conjugated system （—C₆H₄ —, …） and Q is the connecting link between the two conjugated systems. discovered that even if B—K and K—A are insulated by such group as —NH—CH₂—, —COH, or —CH₂CONH—, the compounds are still colored and he explained that the color is due to intermolecular conjugation.The same type of compounds could be prepared from gallic acid: among which compounds Ⅱ Ⅳ and Ⅴ are unknowns. In comparing the color of the compound Ⅰ with Ⅱ or Ⅲ with Ⅳ and Ⅴ, we are convinced that the color of these compounds could be explained by theory.更多还原
