Using metallation and cross‐coupling reactions, we report the synthesis of a new series of push‐pull compounds with a pyrido[4,3‐ d ]pyrimidine system as the central core. Two of them were tested and their NLO properties highlighted. Incorporation of triple and double bonds as spacer between the central core and the substituted aryl groups has been performed to allow an extension of conjugation.
