Mechanically Interlocked Nitrogenated Nanographenes

Herein,
we report the synthesis of mechanically interlocked nitrogenated
nanographenes. These systems have been obtained by clipping different
tetralactam macrocycles around a 1.9 nm dumbbell-shaped nitrogenated
nanographene. Thermal, optoelectronic, and electrochemical characterization
of the different mechanically interlocked nanographenes evidence enhanced
thermal and photochemical stability, and also absorption and emission
properties that vary with the structure of the macrocycle.

本文报道了机械互锁型氮化纳米石墨烯（nitrogenated nanographenes）的合成研究。该类化合物通过将不同的四内酰胺大环（tetralactam macrocycles）套合于1.9 nm哑铃形氮化纳米石墨烯外围制得。对不同机械互锁型纳米石墨烯开展的热学、光电子学及电化学表征结果表明，其热稳定性与光化学稳定性均得到提升，且其吸收与发射特性随大环结构的不同而发生变化。
