A method comprising reducing an acenequinone to form an acenepolyhydrodiol by exposing the acenequinone to a reducing environment comprising an alkoxyaluminate.

The invention provides a triplet acceptor material with up-conversion circularly polarized luminescence and a preparation method and application thereof. The triplet acceptor material comprises a chiral structure compound as shown in a formula I or a formula II in the specification. The material has a chiral structure and contains an acene structure in the structure, so that the material can be used as an energy acceptor of a triplet annihilation up-conversion system, and can be matched with an energy donor to achieve the targets of photon up-conversion and emission of circularly polarized light. The triplet acceptor material has great application value in the aspects of chiral photocatalysis, biological imaging, and processing, displaying and storage of optical information.

The invention discloses a novel aza-condensed ring compound, its preparation method and application. The present invention has synthesized a novel aza-condensed ring compound through a very simple method, and its general chemical structure is shown in formulas (IX), (X), and (XI), wherein AR is the number of benzene rings ≥0 condensed rings, benzene ring azaheterocycles, fused ring benzazene heterocycles, benzene rings connected to halobase azaheterocycles or condensed rings connected to halobase azaheterocycles, R is ≥ 12 carbon atoms straight-chain or branched-chain alkyl groups. The synthesis method of the invention is simple and convenient, and the compound has good solubility. Compared with other acene structures, the method synthesizes a series of acene analogues with fewer steps and higher yield. The series of products synthesized by this simple method can obtain a structure with an effective conjugate length of more than sixteen rings, which is extremely conducive to the transmission of electrons, and the maximum absorption wavelength is in the visible light field. The battery (OPV) field has potential application prospects.

The present invention provides soluble, stable singlet fission (SF) compounds, compositions, materials, methods of their use, and methods for their preparation that provide efficient intramolecular singlet fission (iSF) and multiple excitons. The SF compound may be a dimer, an oligomer, or a polymer of polyoligoacenes, where for example, the compound achieves a triplet yield reaching about 200% per absorbed photon. In this system, SF does not depend on intermolecular inter-actions. Instead, SF is an intrinsic property of the molecule and therefore occurs independent of intermolecular interactions. Singlet fission has the potential to significantly improve the photocurrent in single junction solar cells and thus raise the Shockley-Queisser power conversion efficiency limit from about 33% to about 46% or greater. Quantitative SF yield at room temperature has only been observed in crystalline solids or aggregates of higher acenes.
