An series of 2,7-disubstituted anthraquinone derivatives including a formula I are provided. R is a first substituted group selected from a group consisting of a hydrogen, an amino group, a nitro group, a hydroxyl group, a C1-C12 alkyl group, a C1-C12 alkyl halide group (-(CH2)nX), a C3-C12 cycloalkyl group, a benzyl group, a C1-C12 alkylamino group, a C5-C12 nitrocycloalkyl group and a heterocyclic group, n satisfies 1<=n<=12 and X is an atom selected from a group consisting of a fluoride (F), a chloride (Cl), a bromide (Br) and an iodine (I). The preparation method of the 2,7-disubstituted anthraquinone derivatives includes the steps of acetylating 2,7-diaminoanthraquinone to be one 2,7-disubstituted anthraquinone derivative, which can be further aminated to be another 2,7-disubstituted anthraquinone derivative.本發明提供一種蒽醌類化合物,具有如式(I)的結構:式(I)其中,R係選自下列取代基其中之一:氫基、胺基、硝基及羥基;(CH2)nH之直鏈烷基、帶有支鏈取代之烷基、及具有一胺基取代之烷基支鏈,且1=n=12;(CH2)nX之直鏈烷基、帶有支鏈取代之烷基、及具有一胺基取代之烷基支鏈,其中1=n=12且該X係選自氟、氯、溴、碘之鹵族元素其中之一;以及C3~C12環烷基及苯基,其中於鄰位、間位及對位更可獨立地選自下列取代基其中之一:氫基、帶有C1~C3支鏈取代之烷基、及具有一胺基的C1-C3烷基;具有一胺基的C1-C12直鏈烷基及帶有支鏈取代之烷基。
