The invention relates to electrically doped semiconducting material comprising iii) at least one electrical dopant selected from metal salts consisting of at least one metal cation and at least one anion and iv) at least one matrix compound of formula 1
wherein each of R1, R2, R1, R2′ is independently selected from H, C1-C6 alkyl, C1-C6 haloalkyl and C6-C14 aryl or both substituents on the same aromatic ring of the xanthene skeleton are hydrocarbyl groups linked with each other to form together an anelated divalent C2-C10 hydrocarbyl group and A and A′ are independently selected from C1-C20 heteroaryl group comprising at least one sp2 hybridized nitrogen atom as well as an electronic device and a compound.
本发明涉及电掺杂半导体材料,包括 iii) 至少一种电掺杂剂,选自至少一种金属阳离子和至少一种阴离子组成的金属盐; iv) 至少一种式 1 的基质化合物
其中,R1、R2、R1、R2′各自独立地选自H、C1-C6烷基、C1-C6卤代烷基和C6-C14芳基,或者在氧杂蒽骨架的同一芳环上的两个取代基都是烃基,彼此相连,共同形成一个elated二价C2-C10烃基,A和A′独立地选自包含至少一个sp2杂化氮原子的C1-C20杂芳基以及电子器件和化合物。
