- In the picoline pyrolysis experiment, the methyl disengages from aromatic ring to form methane firstly, then the following reaction of the aromatic ring is similar to pyridine. 甲基吡啶的熱穩定性比吡啶差,熱解時甲基首先脫離芳香環進入氣相,隨後芳香環的反應途徑和吡啶類似;
- The observation can be due to the presence of extended planar aromatic ring(s) in these ligands that could enhance their DNA intercalating binding ability. DPPZ系列配合物與DNA的結合常數比TATP系列配合物的結合常數平均大一個數量級,表明插入配體的平面越大,與DNA的結合能力越強。
- Polyaramide with easily rotational backbone has higher gas permeability, For two polymers with the samebackbone, gas permeability is higher for one with methyl side group on its aromatic ring. 高分子主鏈的化學結構相同,苯環上帶有側甲基的聚合物有高的氣體透過係數;
