Fusion of benzene, naphthalene, and phenalene rings with the D ring of the planar Blatter radical leads to extension of the π-system and increased spin delocalization. The effect of this π-extension and the position of the ring fusion on the electronic structure of the radicals was investigated by UV-photoelectron spectroscopy and DFT CAM-B3LYP/6-311G(d,p) method. The experimental data obtained for 3 out of 8 derivatives were correlated with DFT-derived ionization energies.
苯环、萘环和苊烯环与平面布拉特自由基的D环融合会导致π体系的扩展和自旋离域的增加。通过紫外光电子能谱和DFT CAM-B3LYP/6-311G(d,p)方法研究了这种π扩展以及环融合位置对自由基电子结构的影响。对8种衍生物中的3种获得的实验数据与DFT推导的电离能相关联。
