Push-pull chromophores have been studied extensively and gained importance throughout the years due to their significant characteristics, such as strong intramolecular charge transfer bands and high second- and third-order optical nonlinearities. These properties make them suitable for application in several areas of optoelectronics, such as organic light-emitting diodes (OLEDs), solar cells, organic field effect transistors (OFETs), and non-linear optical (NLO) devices. Synthesis of D-A-D type chromophores can be achieved by click-type thermal [2+2] cycloaddition and [2+2] cycloaddition-retroelectrocyclization reactions. Dialkylated triazene and aniline-substituted alkynes will be synthesized as the first aim of the thesis. Then, thermal [2+2] cycloaddition and [2+2] cycloaddition-retroelectrocyclization reactions of alkynes with a strong electron acceptors DDQ, TCNE, and TCNQ will be investigated to access target NLOphores. Optoelectronic properties of the target chromophoric structures will be further examined via UV/Vis spectroscopy and computational studies.
