Transport Behavior Associated with Bathochromic Shift in Si and Ge Polymers

Time-of-flight drift mobility experiments have been carried out on poly(di-n-hexylsilylene) (PDHS) and poly(di-n-butylgermylene)(PDBG) over a wide range of temperature and electric field. A change in transport behavior in PDHS and PDBG associated with the conformational transitions which are responsible for the bathochromic shift in these polymers, is unambiguously demonstrated.
