摘要
CdSe nanocrystals were modified with small ligand molecules in order to render them compatible with a conducting polymer matrix. Modified NCs were characterized by NMR, optical spectroscopy, electro-electrochemistry. Hybrid materials based on such modified nanocrystals and a conducting polymer (MDMO-PPV, chemistry. P3HT or P3OT) were prepared, characterized, and tested in photovoltaic devices. Modified NCs quench the polymer PL in solutions as well as in films. Photovoltaic devices display modest power conversion efficiencies mainly due to phase segregation.
