A series of 2‐methylpyrimidine skeleton‐based electron‐transporting derivatives (BPyMPM) are designed and synthesized to investigate the influence of substituted pyridine rings on the physical properties and electron mobilities (μe). The only structural difference is the position of substituted pyridine rings. The melting point (Tm) of B4PyMPM is estimated to be ca. 50 °C higher than that of B3PyMPM
一系列2-甲基嘧啶基骨架电子输送衍生物(BPyMPM)的设计和合成以调查取代的吡啶环上的物理性能和电子迁移率(影响μ ë)。唯一的结构差异是取代的吡啶环的位置。B4PyMPM的熔点(T m)估计为。比B3PyMPM高50°C,比B2PyMPM高120°C。使用紫外光电子光谱法测量,观察到电离电势按B2PyMPM(6.62 eV) B3PyMPM(88 meV)> B4PyMPM(76 meV)的顺序降低,而B2PyMPM的位置障碍为2.7,B3PyMPM的位置障碍为<1.5 B4PyMPM。
