Abstract:
1. A method of patterning a layered material, comprising: providing a layered material; forming a photoresist layer on the layered material; patterning the photoresist layer by a focused laser beam to expose a part of the layered material; and etching the exposed part of the layered material to pattern the layered material, wherein the photoresist layer has a chemical structure as shown in Formula 1, 2, 3, 4, 5, 6, or 7, and the Formulae are as follows: wherein each A independently represents a substituted or a non-substituted cyclic alkyl group; R each R each X each X each X wherein each B independently represents a substituted or a non-substituted aromatic hydrocarbon ring, a substituted or a non-substituted aromatic heterocyclic ring, or a substituted or a non-substituted condensed ring including an aromatic hydrocarbon ring; each R each X each R M represents Fe, Co, Cu, Ni, or Zn; wherein C represents a substituted or a non-substituted cyclic alkyl group; each L independently represents a substituted or a non-substituted methine group; each R each X each X each X each m independently represents an integer of 0 or 1; wherein each L′ independently represent a substituted or a non-substituted methine group; each R R each X each X X n is an integer of 0 or 1; wherein each L″ independently represent a substituted or a non-substituted methine group; each R R each X each X each X each k independently represents an integer of 0 or 1; wherein each L′ independently represent a substituted or a non-substituted methine group; R each X each X X n is an integer of 0 or 1.
