Photoinduced electron transfer between a self-assembled resorcinarene-[60]fullerene complex and poly(3-hexylthiophene) in Langmuir-Blodgett films

In the present study, a etoxymethylresorcinarene (EMR) is used as a trap fo r C-60 molecules at the air-water interface. The resulting self-assembled E MR:C-60 complexes form stable well-ordered monolayers which can be easily t ransferred to a solid substrate. The interlayer charge transfer between pol y(3-hexylthiophene) (PHT) and C-60 was studied using the time-resolved Maxw ell displacement charge (TRMDC) method. The structural details of the EMR m olecule were calculated by means of molecular mechanics, semiempirical and ab initio methods. The computational results predict that there is enough s pace for the C-60 molecule to be placed between the tails of the resorcinar ene molecule.
