dinuclear platinum(II) complex of (dfppy)2Pt2(dipic-BTICz) were synthesized as a single-component emitter used in the white polymer light-emitting diodes (WPLEDs), where dfppy is 2-(2,4-difluorophenyl)pyridine and dipic-BTICz is an anion of H2dipic-BTICz. The photophysical and electrochemical properties of (dfppy)2Pt2(dipic-BTICz) were investigated. Compared with the reported mononuclear platinum complex
含有二苯并三苯胺取代的吲哚[3,2- b ]咔唑(BTICz)单元的H 2二斜-BTICz的新型双吡啶甲酸衍生物及其(dfppy)2 Pt 2(dipic-BTICz )的双核铂(II)配合物合成为用于白色聚合物发光二极管(WPLED)的单组分发射极,其中dfppy为2-(2,4-二氟苯基)吡啶,didic-BTICz为H 2 dipic-BTICz的阴离子。研究了(dfppy)2 Pt 2(dipic-BTICz)的光物理和电化学性质。与报道的(dfppy)Pt(pic),(dfppy)2 Pt 2的单核铂络合物相比(dipic-BTICz)在稀二氯甲烷(10 -5 M)中在434 nm处显示红移的光致发光峰,但在其纯膜中除了在445 nm处的固有发射外,在640 nm处减弱并发生红移的聚集发射峰。在掺杂了(dfppy)2 Pt 2(dipic-BTICz)的单发射层(dfppy)中,
