eng	Push-Pull Molecules: Various Shapes, Broad Applications	Organic π-systems end-capped with an electron donor (D) and an electron acceptor (A) represent a class of molecules widely known as push-pull systems. The interaction between D and A through π system generates a new molecular orbital (MO). Excitation of electrons within a new MO can be achieved using visible light, therefore push-pull molecules generally are coloured. These compounds can take various shapes, resembling letters of an alphabet. By varying of types and spatial arrangements of D, π, and A parts in the push-pull molecules, shapes resembling for example letters Y or X can be obtained. In general, organic push-pull molecules are being used in material chemistry, organic electronics and optoelectronics. Thanks to their respective properties such as light absorption and emission, those molecules may, among others, be found acting as active substances in organic light-emitting diodes (OLEDs), dye-sensitized solar cells (DSSCs), two-photon absorbers (2PAs) etc.	Push-Pull Molecules; visible light; OLEDs; optoelectronics
