摘要：

The impact of molecular packing and alignment of 7,14 -bis ((triethylsilyl)ethynyl)dibenzo[b, def]chrysene (TES-DBC) and 7,14-bis((triisopropylsilyl)ethynyl)dibenzo[b,def]chrysene (TIPS-DBC) on OFET performance was investigated. The bulk solid state packing of these angular polycyclic aromatic hydrocarbons (PAHs) was analyzed via single crystal X-ray analysis, and their molecular stacking arrangements on HMDS modified SiO2 substrate were studied using near edge X-ray absorption fine structure spectroscopy (NEXAFS) at the carbon K-edge. Our studies found that TES- and TIPS-DBC have significantly different solid state packing arrangements and tilt angles, yet have OFET mobilities that are comparable at 1.6 x 10(-3) and 1.0 x 10(-3) cm(2)/Vs, respectively. The deposition method also has a dramatic impact on film morphology.
