Novel Series of Diaminoanthraquinone-Based π-Extendable Building Blocks with Tunable Optoelectronic Properties

[Image: see text] We have achieved the first series of DAAQ-based building blocks, viz., n-TIPS-DAAQs (n = 1–4), and unraveled a rational design of their π-extension. Sequentially increasing numbers (n) of the exocyclic π-linkers showed (a) a systematic bathochromic shift in both absorption and emis...

description [Image: see text] We have achieved the first series of DAAQ-based building blocks, viz., n-TIPS-DAAQs (n = 1–4), and unraveled a rational design of their π-extension. Sequentially increasing numbers (n) of the exocyclic π-linkers showed (a) a systematic bathochromic shift in both absorption and emission spectra, (b) selective stabilization of the lowest-unoccupied molecular orbital (LUMO), and (c) unselective changes in the S(0)/S(1) states. To our surprise, the LUMO level of 4-TIPS-DAAQ (−3.72 eV) was found to be comparable to that of PC(60)BM.
