We report a facile and efficient method for the covalent 2D-patterning of monolayer graphene via laser irradiation. We utilized the photo-cleavage of dibenzoylperoxide (DBPO) and optimized the subsequent radical additions to non-activated graphene up to that level where controlled covalent 2D-patterning of graphene initiated by spatially resolved laser writing is possible. The covalent 2D-functionalization of graphene, which is monitored by scanning Raman microscopy (SRM) is completely reversible. This new concept enables write/read/erase control over the covalent chemical information stored on the graphene surface.
我们报道了一种通过激光辐照对单层石墨烯进行共价二维图案化的简便高效方法。我们利用过氧化二苯甲酰（DBPO）的光裂解，并将随后的自由基加成反应优化至一定程度，使得通过空间分辨激光写入引发的石墨烯可控共价二维图案化成为可能。通过扫描拉曼显微镜（SRM）监测的石墨烯共价二维功能化是完全可逆的。这一新概念实现了对存储在石墨烯表面的共价化学信息的写入/读取/擦除控制。
