聚二氯磷腈(PDCP)与N-(6-羟基己基)咔唑发生亲核取代,得到了热稳定性良好(约290℃)、玻璃化温度较低(约36℃)的光电导材料聚双(6-咔唑基己氧基)磷腈。稳态荧光光谱表明,N-(6-羟基己基)咔唑和聚双(6-咔唑基己氧基)磷腈的荧光发射最大波长分别在410nm和393nm,其荧光强度相比于咔唑的最大波长420nm依次减弱并发生蓝移;瞬态荧光光谱表明聚磷腈的线型主链结构和孤立的dπ-pπ杂化轨道体系导致其空间位阻增大,破坏了原有的共轭体系,使聚双(6-咔唑基己氧基)磷腈在不同发射波长下的荧光寿命普遍减小。
Nucleophilic substitution of PDCP and N- (6-hydroxyhexyl) carbazole gave a photoconductive material with good thermal stability (about 290 ° C) and low glass transition temperature (about 36 ° C) Poly bis (6-carbazolylhexyloxy) phosphazene. The steady-state fluorescence spectra showed that the maximum fluorescence emission wavelengths of N- (6-hydroxyhexyl) carbazole and polybis (6-carbazolylhexyloxy) phosphazene were 410 nm and 393 nm, respectively, The maximum wavelength of 420nm in turn weakened and blue shift occurs; transient fluorescence spectra show that polyphosphazene linear backbone structure and isolated dπ-pπ hybrid orbital system resulting in increased steric hindrance, the destruction of the original conjugate System, polybis (6-carbazolylhexyloxy) phosphazene generally has a different fluorescence lifetime at different emission wavelengths.
