Our results indicate that the dimerized model is the most stable configuration for both ethylene and acetylene when the converge is 0.5 ML, while the end-bridge configuration becomes the most favorable structure when the converge increases to 1.0 ML.

结果表明：无论是吸附乙炔还是乙烯分子，当覆盖度为0.5 ML时，最为稳定的吸附方式为dimerized模型；当覆盖度增大到1.0 ML时， end-bridge模型为最稳定的吸附方式。

Therefore, the pre-fabricated functional surface containing azide groups can be covalently anchored through click-chemistry by newly designed acetylene-appended HBCs. These HBC derivatives not only possess the potential in the formation of SAM, but their alignment modes of edge-on or face-on could be controlled by tailor-made molecular design.

因此，我们设计出末端带有乙炔官能基之HBC分子，希望在预先处理并带有叠氮(-N3)官能基的基板表面上进行click-chemistry (速配组合式化学、点击化学)，利用共价键之形式将HBC分子镶嵌於基板表面，除了藉此制作出分子自组装单层薄膜之外，利用分子设计进一步控制其排列方式为edge-on或是face-on。
