    摘要: The present invention provides a highly sensitive and highly durable electrophotographic photoconductor providing a conductive support and a photosensitive layer formed thereon, the photosensitive layer comprising a bis-enamine compound of the formula (I): ##STR1## wherein "A" is a C.sub.6-12 arylene group which may have a substituent, a bivalent heterocyclic reside which may have a substituent, a C.sub.2-4 lower alkylene group which may have a substituent; "B" is a lower dialkylamino group, a lower alkoxy group, a lower alkyl group, a hydrogen atom or a halogen atom; and k is an integer from 1 to 5 provided that when k is an integer of 2 or more, "B" may be identifcal or different, may together form a ring; and n is an integer from 2 to 4. The electrophotographic photoconductor according to this invention is excellent in stability resisting fluctuations in temperature and humidity, high in electric chargeability, almost free from reduction in photosensitivity in repetitive use and also free from deterioration in image quality such as defection in toner images.

In particular, they can be used to prepare organopolysiloxanes having nonlinear optical properties and containing side groups of the general formula Ia ##STR2## in which the variables are as defined above. These novel organopolysiloxanes having nonlinear optical properties are also highly suitable for the production of Langmuir-Blodgett layers.
