Future challenges in the field of communication rely upon new discoveries in materials on the nanometer-length scale. Thus, the success of nanomachines depends on overcoming two challenges: (1) Fabrication of nanomachines with proper precision, lifetime, and efficiency; and (2) The effective communication with faster data transfer rate with minimum channel bit error. The current nanocommunication systems are based on mechanical phenomena, which show propagation delay and insufficient satisfactory in achievable data throughputs. <br/>Fröster Resonance Energy Transfer (FRET), a rapid non-radiative phenomenon is a promising paradigm that allows future molecular-size machines to communicate with each other over distances up to tens of nanometer. Low dependence on environmental factors, controllability of intermolecular distance, spectral similarity, and relatively wide signal transfer range make FRET also a promising candidate to be used for high-rate nanoscale wireless communication. Harnessing light-induced FRET by introducing donor-acceptor pair architecture to a nanostructured platform, molecular-level communication may allow rapid signal transfer (information bits) that occurs in nanoseconds at the proximity of usually 1-10 nm distance and can be simultaneously used in different parts of a nano-network as nano-antennas, which is like a wireless spectrum band in a cellular network.<br/>To meet this requirement, we developed a series of novel higher order nanoassemblies, bearing fused arene-based donor and acceptor moieties to exhibit long range molecular communicating properties with possessing large and stable FRET distance. The research described here pursued theoretical and experimental approaches to predictive design, synthesis, and cascading a signal via FRET energy transfer process. A quantum mechanical model of these systems used to computationally simulate energy transfer while tuning and optimizing surface scattering for signal longevity. Specific manipulation of thickness and dielectric constant of the donor-functionalized nanoporous thin films evidenced to be effective variables for device modification.
