Herein we present the synthesis and the photochemical behavior of several new hemicarcerands containing anthracene units as photoactive species. By means of NMR investigations of compounds 9 and 11 the dimerization mode was revealed as a 9,10-9′,10′-dimerization, classically known from anthracene. Nevertheless only compound 11 could be converted to the opened form upon irradiation with 300 nm. Reopening of compounds 9 and 10 could not be achieved so far either by heating or by irradiation.
在此,我们介绍了几种含有蒽单元作为光活性物种的新型半氯化石蜡的合成和光化学行为。通过对化合物 9 和 11 的核磁共振研究,我们发现其二聚化模式为 9,10-9′,10′-二聚化,这在蒽中是众所周知的。然而,只有化合物 11 可以在 300 纳米波长的照射下转化为开放形式。化合物 9 和 10 至今无法通过加热或辐照重新开放。
