Billions of years of evolution has produced a variety of functional and complex components that enable life on Earth. The notable examples are chlorophylls that have a vital role in converting the energy of the Sun into chemical energy, and nucleobases that act as the building blocks in DNA/RNA, which store and convey the genetic information in living organisms.
The thesis investigates synthetic supramolecular chlorophyll-polymer assemblies that mimic the biological antenna structure. The work establishes how the increasing chlorophyll density or varying the chemical structure of the molecules changes the optical response within the assemblies. Moreover, atomic/molecular layer deposition is utilized as a novel method to create fundamentally new three-dimensional sodium networked uracil assemblies with intriguing optical properties. The thesis also further develops economical nanofabrication methods to create large-scale plasmonic substrates for Raman scattering and fluorescence enhancement.
The results obtained in this thesis could pave the way for new biomimetic photonic materials and enable the utilization of economic and large-scale nanofabrication methods in creating new plasmonic materials.
