A solution-processable material for the fabrication of optical reflector and organic memory device is disclosed having a donor–acceptor system consisting of a boron (III) moiety as the electron acceptor unit. More specifically, described herein is the utilization of boron (III) -containing donor–acceptor compounds having a chemical structure represented by the following general formula (I) as active material for the fabrication of optical reflectors and organic memory devices. wherein B is a boron atom； each boron atom can attach optionally one or two of the X1, X2, X3 and X4 and two of the Y1, Y2, Y3, and Y4； X1, X2, X3 and X4 are independently a heteroatom or carbon atom, where the heteroatom or group can be F, Cl, Br, I, or OR, and R is a substituent on specific heteroatom or carbon atom which can be selected from alkyl or aromatic groups； Y1, Y2, Y3, and Y4 are independently a heteroatom, where the heteroatom or group can either be O, S, Se, Ge, Te, PR, or NR, and R is a substituent on specific heteroatom or carbon atom which can be selected from alkyl or aromatic groups； Z1, Z2, Z3, and Z4 are cyclic structure derivatives； D1, D2 and D3 are optionally alkyl substituted aromatic groups； and n and m can optionally be any integer. |
