helical molecule. Photophysical and chiroptical properties of these benzopicene and azabenzopicene derivatives have also been examined. With respect to photophysical properties, substituted benzopicenes and azabenzopicenes showed red shifts of absorption and emission maxima compared with the corresponding triphenylenes and azatriphenylenes. With respect to chiroptical properties, the CPL spectra of

铑(I)/ H 8可以方便地合成取代的苯并
吡啶和氮杂苯并
吡啶在温和条件下,–BINAP或BINAP络合物催化的[2 + 2 + 2]环加成反应。该方法用于合成基于苯并
吡啶的长阶梯和螺旋分子。X射线晶体结构分析表明,基于苯并
吡啶的螺旋分子高度扭曲,并且环的平均重叠距离明显小于基于三苯撑的螺旋分子。还已经检查了这些苯并
吡啶和氮杂苯并
吡啶衍生物的光物理性质和手性性质。关于光物理性质,与相应的三亚苯基和氮杂三苯并苯相比,取代的苯并二苯并氮杂和苯并氮杂苯并烯显示出最大吸收和发射红移。就手性而言,基于苯并
