Tarkuc, Simge published the artcileThe relationship between molecular structure and electronic properties in dicyanovinyl substituted acceptor-donor-acceptor chromophores, Name: 9,10-Diethynylanthracene, the publication is Tetrahedron (2017), 73(33), 4994-5004, database is CAplus.
In this contribution the authors describe a combined exptl. and theor. study of the relation between the mol. structure and the electronic properties of conjugated donor-acceptor type chromophores for light-harvesting applications. A series of model systems was synthesized where a central anthracene (electron donor) is connected to dicyanovinyl units (electron acceptor) through a π-conjugated spacer. The study of the redox and optical properties of these chromophores and of reference compounds without dicyanovinyl units allows the authors correlate the electronic properties to the presence of the electron withdrawing groups and the mol. conformation. Comparison with calculated electronic structure shows that the construction of chromophores that consist of electron donating and accepting units does not always follow the simple rules that are generally used in the design of such mols. The results show a subtle relation between the charge transfer character and the geometry of the mols. In some cases this leads to significant contribution of charge transfer excitation to the absorption spectra of some chromophores while such contributions are completely absent in others.
