Pyrenophane (6) and an octaphenyl derivative (16) were synthesized using two different routes. Both cyclophanes contain a severely bent pyrene unit (6: theta = 93.6 degrees and 16: theta = 95.8 degrees , according to DFT-calculations (B3LYP/6-311G**)), which was generated at room temperature by a valence isomerization/dehydrogenation (VID) reaction. HOMA and NICS indicate 92-98% retention of aromaticity
                                    使用两种不同的途径合成了
邻苯二酚(6)和八苯基衍
生物(16)。根据DFT计算(B3LYP / 6-311G **),两个环烷均含有严重弯曲的pyr单元(6:theta = 93.6度和16:theta = 95.8度),这是在室温下通过化合价/脱氢(VID)反应。HOMA和NICS表明,与平面pyr相比,高度扭曲的systems体系保留了92%至98%的芳香性。
