Df. Perepichka et al., Push-pull dithiole - fluorene accepters as electron transport materials for holography, SYNTH METAL, 121(1-3), 2001, pp. 1487-1488
A comparative investigation of photoconductivity sensitisation of poly-N-(2
,3-epoxypropyl)carbazole (PEPK) by push-pull accepters of the fluorene seri
es shows that intramolecular charge transfer (ICT) in these accepters leads
to a significant increase in the electrophotographic response. However, hi
gh stability of the radical anion of the acceptor is also a necessary.
