説明
Photoconductivity of a polyimide with an alicyclic diamine [the polyimide film prepared from pyromellitic dianhydride and diaminodicyclo hexylmethane PI(PMDA/DCHM)], and an aromatic polyimide [the polyimide film prepared from pyromellitic dianhydride and oxydianiline PI(PMDA/ODA)] was investigated by the addition of an electron donor, N,N,N′N′-tetramethyl-p-phenylenediamine (TMPD). The addition of the electron donor increased the photocurrent generation of two polyimide films by about three orders of magnitude shifting to longer wavelength by forming intermolecular charge-transfer complex in the ground state of the polyimide films. The polyimide with the alicyclic diamine doped with the electron donor showed a larger enhancement of photocurrent probably due to the existence of only intermolecular charge-transfer complex in the polyimide film, compared to the case of the aromatic polyimide having charge-transfer complex both intra- and intermolecularly. The mechanism of the enhancement of photocurrent by the addition of the electron donor would be first due to photo-absorption by the intermolecular charge-transfer complex formed between the added electron donor and pyromellitic imide unit of the polymer backbone. Under an applied field, its excitation is followed by rapid electron transfer from the donor to pyromellitic imide to produce the radical anion of the polymer and the radical cation of the donor, resulting in the photoconductivity in the bulk polyimide films.
