A series of novel organic conjugated molecules (5a-5d) comprising 2,3-benzopyridiazine as electron-withdrawing core and thiophene derivatives as electron-donating arms have been synthesized successfully in good yields. The ultraviolet-visible (UV-Vis) absorption spectra and fluorescence spectra of 5a-5d revealed that the optical properties are strongly influenced by the interactions between nitrogen and sulfur atoms in the conjugated backbone, as well as the position of the alkyl chains in the thiophene rings. The experimental results and theoretical calculation data clearly indicated that the band gap and the energy levels of LUMO and HOMO could be fine-tuned by the position of alkyl chains in the thiophene rings. Thus, the structure-property correlation of this class of conjugated molecules can be well established. A series of organic conjugated molecules containing 2,3-benzopyridiazine as electron-withdrawing core and thiophene derivatives as electron-donating arms have been synthesized successfully. The optical properties and electrochemical behaviors of these molecules can be fine-tuned through changing the position of alkyl chains in the thiophene rings. Copyright
