eng	Heterocyclic Moieties in Push-Pull Molecules: Design, Synthesis and Property Tuning.	Organic pi-conjugated molecules attract considerable attention of organic as well as material chemists. Especially those having push-pull arrangement possess unique and peculiar properties such as dipolar character, colour, electrochemical and (non)linear optical properties. Direct interaction of the electron donor and acceptor in D-pi-A systems results in so-called intramolecular charge-transfer (ICT) and these systems found widespread application across the fields and devices such as NLO, DSSC, OLED, OFET etc. In my group, several new classes of push-pull molecules of various shapes and lengths were developed to date. In these derivatives, heterocyclic moieties were employed as a part of the pi-conjugated path and, more often, as new heterocyclic accepting moieties. Hence, in this contribution, new heterocyclic pi-conjugated scaffolds, their design, synthesis, property tuning and applications will be reviewed. Five membered imidazole, thiophene as well as six membered pyridine, pyrazine, pyrimidine etc. will be discussed. Applications of such derivatives span the nonlinear optics, two-photon absorbers, guest molecules for intercalation and photoredox catalysts.	push-pull molecules, nonlinear optics, intramolecular charge-transfer, imidazole, thiophene, pyridine, pyrazine, pyrimidine
