Squaraine dyes containing diphenylamine group: Effects of different type structures on material properties and organic photovoltaic performances

Four donor-acceptor-donor (D-A-D’) unsymmetrical squaraines (USQs) with different molecular skeletons (XZ-type and YZ-type), containing diphenylamine group with/without methoxy substituent were synthesized as donor materials in bulk-heterojunction (BHJ) organic photovoltaics (OPVs). The introduction of methoxy group in USQs has little different effects on the overall photovoltaic performance. Conversely, the different molecular skeleton types of the USQs have significant influence on their material properties and photovoltaic performances. Compared to BIDPSQ and BIDPOMeSQ with XZ-type molecular skeleton, IDPSQ and IDPOMeSQ with YZ-type molecular skeleton display closer solid-state packing, much lower highest occupied molecular orbital (HOMO) energy level, higher hole mobility and smaller phase separation domain size. Consequently, YZ-type USQs exhibit the most excellent performance with power conversion efficiency (PCE) of ~4%, which is approximately 300% higher than those of XZ-type USQs. Surprisingly, even though IDPSQ and IDPOMeSQ show wide band gaps, the corresponding devices still achieve a highest PCE of ~4%, which is comparable to or even higher than the PCEs of some reported SQ-based devices with low band gaps. These results indicate the YZ-type molecular skeleton and the electron-donating diphenylamine group are very promising to construct highly efficient squaraine donor materials.

Asymmetric squaraine material as well as preparation method and application thereof

The invention belongs to the technical field of preparation of squaraine materials and in particular relates to an asymmetric squaraine material as well as a preparation method and application thereof. According to the asymmetric squaraine material, C1 and C2 substituent groups are designed and selected, so that a spectral absorption peak of the material is located in a blue green light absorptionregion and the material is used for preparing an organic green blue light-sensitive device; application requirements in green blue sensing and multi-channel light communication fields; meanwhile, theabsorption half-peak width under an asymmetric squaraine material solution and the absorption half-peak width under a thin film state are less than 110nm and the asymmetric squaraine material has very important application in the aspect of photosensitive diodes. Furthermore, the material provided by the invention has strong stability and can meet various technologies including evaporation, spin-coating, inkjet printing and the like.
