heal.abstract	The reaction of acenaphthenequinone - a low-cost commercial product with an insulator's behavior - with an active methylene (malononitrile CNCH2C(N) was carried out. This is a simple, one-pot reaction with satisfactory efficiency. Setting the experimental procedure, the introduction of one or two nitrile groups in the original molecule was made possible. In fact, a new product was synthesized, in the second case. Afterwards, the photoconductivity of the as-prepared materials was measured. Thanks to the development of extended pi-conjugated systems, as proved, the products show a remarkable photosensitivity. This synthesis can be also applied even to other active methylene compounds, such as ethyl cyanoacetate (NCCH2COOEt) [I. Mhaidat, S. Hamilakis, C. Kollia, A. Tsolomitis, Z. Loizos, Mater Lett 2007;61:321-325] and generally to nucleophilic reagents, such as p-anisidine(p-NH2C6H4OMe) [I.. Mhaidat, S. Hamilakis, C. Kollia, A. Tsolomitis,Z. Loizos, Mater Lett 2005;60:147-149). (c) 2008 Elsevier B.V. All rights reserved.	en
