eng	Synthesis and property tuning in organic push-pull molecules	Organic molecules with all -conjugated scaffolds are currently tremendously investigated organic materials. Such molecules can be widely found in (opto)electronic devices such as nonlinear optical (NLO) materials and memories, organic light-emitting diodes (OLEDs), dye-sensitizing solar cells (DSSCs), semiconductors, switches and many others. Moreover, in a -conjugated system end-capped with electron donors D (e.g. NR2 or OR groups) and electron acceptors A (e.g. NO2 or CN groups) intramolecular chargetransfer (ICT) from the donor via -system to the acceptor occurs. Such dipolar push-pull molecules represent unique class of compounds with distinct optical and electrochemical properties. In our continuing synthetic efforts, we have developed several series of organic push-pull D--A systems and have thoroughly investigated their structure-property relationships. In general, the property tuning of push-pull chromophores can be achieved by the modification of the electronic nature of appended donors and acceptors as well as variation of the -linker. Brief synthesis of several representative derivatives and tailoring of their electronic properties will be discussed.	push-pull system, intramoleculat charge transfer, structure-property relationships, chromophore
