eng	SYNTHESIS OF D-p-A-p-D SYSTEMS BASED ON INDAN-1,3-DIONE	The design of nonlinear optical (NLO) molecules has become a focus of current research in view of their potential applications in various photonic technologies. Materials with NLO activity found use as electro-optic switching elements for telecommunication and optical information processing. A typical organic push-pull chromophore with second-order nonlinear optical (NLO) properties consists of an electron donor and an electron acceptor interacting through a p-conjugated spacer. Indan-1,3-dione and 3-dicynomethylidene-1-indanone have been chosen as main acceptor moieties of the proposed organic D-p-A-p-D systems. This strong acceptor system was further modified by electron donors such as N,N-dimethylamino group either on C2 or the fused benzene ring. The donor groups were linked to the benzene ring through the p-linkers of various shapes and lengths in order to finely tune the NLO properties.	indan-1,3-dione; chromophore; D-p-A-p-D systems
