Abstract

Electrophotographic materials used in a photoconductor include p-tricyanovinyl-phenyidicyanomethide (TCVPDM, I) (CN)2c = C C(CH)2 (I) and the reaction product of this material with an acceptor such as 2,4,7-trinitro-fluorenone (TNF) thereby resulting in a material of the following formula:

ORGANIC DONOR~ACCEPTOR COMPOUNDS

Electrophotographic materials used in a photoconductor include p~tricyanovinyl~ phenyidicyanomethide (TCVPDM, I)

and the reaction product of this material with an acceptor such as 2,4,7~trinitro~ fluorenone (TNF) thereby resulting in a material of the following formula:

TCVPDM~ TNF

The donor~acceptorinteraction between the donor of the formula mentioned above and various neutral and cationic acceptors results in charge-transfer absorption in the near infrared region of the spectrum and hence to sensitivity in this region.

Illustrative examples of materials that can be used as acceptors include neutral molecules such as TNF or p-chloranile and cationic acceptors such as triaryl pyrylium or -triapyrylium. One specific material used is the 2,4,6-triphenyl- triapyrylium salt of I. The compound p-tricyanovinyldimethylaniline may be used instead of I in such complexes.
