| Sumario: | Promising materials have been designed and fully characterized by an effective interaction between versatile platforms as carbon nanohorns (CNHs) and conjugated molecules based on thiophene derivatives. Easy and non-aggressive methods have been described for the synthesis and purification of the final systems. Oligothiophenephenylvinylene (OTP) systems with different geometries and electron density are coupled to the CNHs. A wide range of characterization techniques confirms the effective interaction between the donor (OTP) and the acceptor (CNH) systems. These hybrid materials show potential on their integration in solar cells devices. Importantly, surface-enhanced Raman spectroscopy (SERS) effects are observed without the presence of any metal surface in the system. Theoretical calculations have been performed in order to study the optimised geometries of the non-covalent interaction between the surface and the organic molecule. Calculations allow us to extract information on the monoelectronic energies of HOMOLUMO orbitals and band gap of different donor systems. |
