Abstract:

In this paper, a donor-acceptor-type molecule, 2,2'-(-(((2,9-bis(5-(2-decyltetradecyl)thiophen-2-yl)-6,13-dioxo-6,13-dihydrodiindolo[3,2,1-de:3',2',1'-ij][1,5]naphthyridine-7,14-diyl)bis(thiophene-5,2-diyl))bis(methaneylylidene))bis(3-oxo-2,3-dihydro-1H-indene-2,1-diylidene))dimalononitrile(MT-BAI-TM) was synthesized using the strategy of bay-annulation. The compound possessed deep absorption spectra extending to 820 nm and low-lying LUMO level of -3.98 eV. The distribution of frontier molecular orbits was calculated by density functional theory(DFT). A face-on orientation between MT-BAI-TM molecules in spin-coating film(sample S-1) was observed by grazing incidence wide angle X-ray scattering(GIWAXS). The characteristics of deep absorption, high electron affinity and face-on orientation of the compound indicate the nature of acceptor-type organic semiconductor. Hence, the MT-BAI-TM is an attractive candidate as acceptor materials for potential application in organic photovoltaic devices.
