Lai, Yu-Ying published the artcileSynthesis, Molecular and Photovoltaic Properties of an Indolo[3,2-b]indole-Based Acceptor-Donor-Acceptor Small Molecule, Application In Synthesis of 105752-04-3, the main research area is conjugated polymer indoloindole acceptor donor synthesis photovoltaic property; heterojunction solar cell indoloindole acceptor donor photovoltaic property.
Indolo[3,2-b]indole, containing two fused indole units, is an unexplored but promising electron-rich mol. for constructing donor-acceptor materials due to its planar, sym., and extended conjugated structure. A new synthetic pathway is successfully developed to prepare 2,7-diboronic ester-indolo[3,2-b]indole, which was then reacted with dithienodiketopyrrolo-pyrrole acceptor to afford a new acceptor-donor-acceptor (A-D-A) conjugated mol., 2,7-bis(dithienodiketopyrrolo-pyrrole)indolo[3,2-b]indole (2,7-DPPIIDPP). II is used to stand for indolo[3,2-b]indole in order to emphasize that this compound is constructed from two indole units. The A-D-A linkage through the 2,7-positions of II not only preserves the phenylene units in the para-conjugation but also renders stronger electron-donating strength. This material exhibited good thermal stability, high crystallinity, and broad UV/Vis absorption. The solution-processed bulk heterojunction device using the configuration of ITO/PEDOT:PSS/2,7-DPPIIDPP:PC71BM/Ca/Al exhibited a Voc of 0.72 V, a Jsc of 6.88 mA/cm2, and an FF of 49.6%, leading to a power conversion efficiency (PCE) of 2.45%.
