Abstract
A functional molecular element with a reduced contact resistance between the constituting molecule and the electrode, a method for production thereof, and a functional molecular device are provided herein. The method consists of the following steps. A closely adhering molecular monolayer is formed on the surface of the electrodes from a π-electron conjugated molecule (one species of linear tetrapyrrole) composed of the porphyrin-like nearly discoid skeleton and the flexible side chains (alkyl chains). A π-electron conjugated molecule of the same species as the one or different species from the one is piled on the monolayer by π-π stacking to form the array structure. As the result of the foregoing steps, the π-electron conjugated molecule constituting the first molecular layer of the array structure takes on such a configuration that the flexible side chains adsorb to the surface of the electrode and the discoid skeleton orients parallel to and adheres to the surface of the electrode. The second and subsequent molecular layers constituting the array structure have their piling direction controlled by the π-π mutual action.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
