any undesired shuttling effect from occurring during isomerization. In addition, the insulated structure provides robust optical properties by prevention of intermolecular reactions. Bulky linked rotaxane structures on both sides of the N=N and C=C double bonds suppress E/Z isomerization; photoluminescence quantum yield (PLQY) measurements reveal that this results in suppression of PLQY reduction caused

发光材料,双键的异构化和分子间反应通常是不希望的,因为它们会导致π系统的发光性能下降。在本文中,我们报告了一种新的方法,可通过利用连接的轮烷结构的空间效应同时防止异构化和分子间反应。环单元共价连接以防止在异构化过程中发生任何不希望的穿梭效应。另外,绝缘结构通过防止分子间反应而提供了鲁棒的光学性能。N = N和C = C双键两侧的庞大连接轮烷结构抑制E / Z异构化 光致发光量子产率(PLQY)测量表明,这可抑制由异构化引起的PLQY还原。另外,说明了在光照射和空气气氛下的稳定性的提高。
