Materials with NLO activity found wide use in 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.1 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 (Scheme 1). 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.	INDANDIONE; D-p-A-p-D; CHROMOPHORES
