The carrier transport was investigated depending upon the processes of film preparation in regioregular poly(3-alkylthiophene)s (PATs). The relatively non-dispersive characteristics of photocarrier transport were obtained in drop-cast film. In spin-coated film the transient photocurrent was strong dispersive in contrast. The dispersivity was also slightly increased with the alkyl chain length. The X-ray profiles showed the large crystallinity and the absorption spectra showed the red-shift of peaks in drop-cast film. These results indicate that the dispersivity of carrier transport in PATs is strongly affected by the casting processes of PAT film.

Photocarrier transport in processable poly(3-alkylthiophene) Reviewed

Synthetic Metals 121 ( 1-3 ) 1563 - 1564 2001.03

Authorship：Lead author Language：English Publishing type：Research paper (scientific journal)

Photocarrier transport in soluble poly(3-alkylthiophenes)(PATS) has been studied by means of time of flight method. Temperature and field dependencies of mobility were measured for a number of polythiophene derivatives having various alkyl chain lengths from butyl to octadecyl. It has been found that regioregularity has a marked effect on hole mobility in PATs with shorter alkyl group. The results of the mobility in PAT films are discussed in terms of main chain regularity and alkyl chain lengths.
