An organic memresitor/memcapacitor comprises of two terminal electrodes, each electrode has a membrane made of nanostructure organic conducting polymer of cyclodextrin derivatives attached thereto. By self assembling of cross-linking copolymers forming conductive membranes and separated by a mobile dopant barrier dielectric material, one side of the membrane has structure formed flat horizontal nano-bridges with array larger vertical nanopores underneath the bridge; and another side of the electrode/membrane has a negative mobile dopant polymer network forming arrays nano-islands with the membrane thickness is one third of the opposite membrane to be feasible conducting “head-tail” biphase charge and discharge at wide range of frequencies, so called the low-to-high frequency switch embedded to effectively save energy and storage energy by utilizing functional groups mimicking the positive and negative isopotential poles active sites of the acetylcholinesterase (ACHE) gorge along strengthened by a hydrophobic reagent. This invention also disclosed a method to build an organic Memristor/Memcapacitor having no hydrophobic reagent applied to lining the ACHE gorge and hence it induced an electromagnetic field that was not able to have biphase charge/discharge in an organic media.
