A compound of formula [I]:
X—R [I]
wherein X represents the group:
1
and R is either (i) represented by the formula [II]
2
wherein n is 1 or 2, and the or each R
7
group is independently selected from the group consisting of hydrogen and halogen atoms, cyano, nitro, mercapto, carbonyl and sulfone groups, and optionally substituted alkyl, haloalkyl, hydroxyalkyl, aryl, alkoxy, aryloxy, alkylamino, arylamino, alkylthio, arylthio, ester, siloxy, cyclic hydrocarbon and heterocyclic groups;
or (ii) is selected from the group consisting of optionally substituted alkyl, hydroxyalkyl, aryl, cyclic hydrocarbon and heterocyclic groups;
wherein in each case R
1
-R
6
are each independently selected from the group consisting of hydrogen and halogen atoms, cyano, nitro, mercapto, carbonyl and sulfone groups, and optionally substituted alkyl, haloalkyl, hydroxyalkyl, aryl, alkoxy, aryloxy, alkylamino, arylamino, alkylthio, arylthio, ester, siloxy, cyclic hydrocarbon and heterocyclic groups. The compounds are useful as hole-transporting materials in electroluminescence devices.
一种化合物的化学式为[I]:X-R,其中X代表基团:1,R要么是(i)由式[II]2表示,其中n为1或2,且每个R7基团独立地选择自羟基和卤素原子、氰基、硝基、巯基、羰基和磺酰基,以及可选择取代的烷基、卤代烷基、羟基烷基、芳基、烷氧基、芳氧基、烷基氨基、芳基氨基、烷硫基、芳硫基、酯基、硅氧烷基、环烃和杂环基;或者(ii)选择自可选择取代的烷基、羟基烷基、芳基、环烃和杂环基;在每种情况下,R1-R6各自独立地选择自羟基和卤素原子、氰基、硝基、巯基、羰基和磺酰基,以及可选择取代的烷基、卤代烷基、羟基烷基、芳基、烷氧基、芳氧基、烷基氨基、芳基氨基、烷硫基、芳硫基、酯基、硅氧烷基、环烃和杂环基。该化合物在电致发光器件中作为空穴传输材料有用。
