石墨炔基杂化材料的可控合成与性质研究

As a new material with China's independent intellectual property rights, graphdiyne has been attracted many concerns since it was successfully synthesized in 2010 and it has formed a new research field led by Chinese scientists. However, the hybrid materials based on graphdiyne is still in its infancy. Therefore, the key and major challenges in this area is how to develop some new techniques and methods for preparing graphdiyne hybrid materials and controlling their interaction to achieve effectively control their performance and structures. In this study, it is proposed to construct new graphdiyne hybrid materials through the designing structure by introducing functional groups in graphdiyne and develop new regulation and assembly methods. The functional groups and molecules are introduced into graphdiyne by chemical methods and orientedly assembled with inorganic / organic semiconductors through covalent and non-covalent bonding to construct graphdiyne hybrid materials and control their structure, energy and assembly method to realize the structure and property regulation of graphdiyne hybrid materials. Some new methods and techniques for constructing graphdiyne hybrid materials will be developed. A series of graphdiyne hybrid nanostructures and materials with new properties will be prepared.
