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, and ca. 120 °C higher than that of B2PyMPM. The ionization potential is observed to increase in the order B2PyMPM (6.62 eV) e at 298 K of B4PyMPM is 10 times higher than that of B3PyMPM and 100 times higher than that of B2PyMPM. To extract the charge transport parameters, the temperature and field dependencies of μe are investigated. Using Baessler's disorder formalism, the degree of energetic disorder is estimated to decrease in the order B2PyMPM (91 meV) > B3PyMPM (88 meV) > B4PyMPM (76 meV), and the positional disorder is 2.7 for B2PyMPM, and e) of 2-methylpyrimidine skeleton-based electron-transporters is investigated. Although the structural difference is very small, the difference in μe is found to be quite large. At 298 K, the μe of B4PyMPM is measured to be 10 times higher than that of B3PyMPM and 100 times higher than that of B2PyMPM. Copyright
