In the search for molecular materials,DNA molecules have become an intensively studied topic in the past and recent years.The most important molecular characteristic are that DNA could designing a wide variety of structures and devices resides in its molecular and sub-molecular recognition capabilities.In particular,DNA can form a well ordered and fully controllable stacking structure of π-aromatic compounds by means of π-stacking between the bases.Finding potential applications of DNA has been one of the fascinating subjects because the one-dimensional π-stacked aromatic array formed in DNA seems to be advantageous for charge conduction and magnetic exchange.The primary innovations are related as follows.
