    • The invention relates to a use of a compound according to formula (1), wherein each of R 1 , R 2 , R 1 , R 2 is independently selected from H, C 1 -C 6 alkyl, C 1 -C 6 haloalkyl and C 6 -C 10 aryl or both substituents on the same aromatic ring of the xanthene skeleton are hydrocarbyi groups linked with each other to form together an anelated divalent C 2 -C 10 hydrocarbyi group; X and X' are independently selected from C and N, R 5 is H if X is C, R 5 is H if X' is C, R 5 is lone electron pair if X is N, R 5 is lone electron pair if X' is N, and each of R 3 , R 4 , R 3 , R 4 is independently selected from H and C 6 -C 10 aryl, with the proviso that neither both R 3 , R 4 nor both R 3 , R 4 are aryl at the same time and if X is C, R 3 and R 4 are not H at the same time, and if X' is C, R 3 and R 4 are not H at the same time, or both substituents on the same phenyl or pyridyl ring are hydrocarbyi groups linked with each other to form together a divalent C 4 -C 10 hydrocarbyi group representing an anelated, substituted or unsubstituted, six-membered aromatic ring; in an electron transporting layer or in an electron injecting layer comprised in an electronic device.
    • 本发明涉及式(1)化合物的用途,其中R 1,R 2,R 1,R 2各自独立地选自H,C 1 -C 6烷基,C 1 -C 6卤代烷基和C 6 -C 10芳基, 呫吨骨架的相同芳环是相互连接形成一个双键二价C2-C10烃基的烃基; X和X'独立地选自C和N,如果X是C,R5是H,如果X'是C,则R5是H,如果X是N,则R5是单电子对,如果X'是N,则R5是单电子对, 并且R 3,R 4,R 3,R 4各自独立地选自H和C 6 -C 10芳基,条件是R 3,R 4以及R 3,R 4均不同时为芳基,如果X为C,则R 3和R 4为 不是同时为H,如果X'为C,则R3和R4不同时为H,或同一苯基或吡啶环上的两个取代基均为相互连接的烃基,以形成二价C 4 -C 10 代表非离子取代或未取代的六元芳环的烃基; 在电子传输层或包含在电子器件中的电子注入层中。
