By combining the well-known motifs of BODIPY dyes and cycloparaphenylenes, novel nanohoop derivatives were accessible via established procedures. Absorption and emission spectra showed overall bathochromic shifts, and their photophysical behavior can be tuned by introducing steric demand to modulate the conjugation throughout the system. F NMR spectra underline distinct differences in the conformations, and (TD)DFT calculations provide a deeper insight into the geometry, photophysical behavior, and influence of steric demand.
通过结合硼二吡咯染料和环对亚苯基的著名结构单元,可通过既定程序获得新型纳米环衍生物。吸收光谱和发射光谱显示出整体红移,并且它们的光物理行为可以通过引入空间需求来调节整个体系的共轭作用进行调整。氟核磁共振光谱强调了构象上的明显差异,而(TD)DFT计算则更深入地洞察了几何结构、光物理行为以及空间需求的影响。
