Embodiment 1

[0074] Embodiment 1: Preparation of NITI-1

[0075]

[0076] 1) Preparation of compound 3: N 2 Under ambient conditions, compound 1 (0.1mmol) and compound 2 (0.3mmol) were dissolved in 3mL sodium carbonate solution (2M) and 6mL dioxane mixed solvent, added tetrakis (triphenylphosphine) palladium (0.026mmol), avoid After reacting at 95°C for 16 h, the solvent was rotated off under reduced pressure, and the residue was separated by column chromatography to obtain orange compound 3 with a yield of 65%. MS(MALDI-TOF):1065.2[M] + .

[0077] 2) Preparation of NITI-1: N 2 Under ambient conditions, compounds 3 (0.065mmol) and 4 (0.390mmol) were dissolved in 6mL of chloroform solution, 3 drops of pyridine solution was added dropwise, reacted at 75°C for 16h, the solvent was spinned off under reduced pressure, and the residue was separated and purified by column chromatography to obtain black Product NITI-1, yield 86%. MS(MALDI-TOF):1417.3[M] + .

Embodiment 2

[0078] Embodiment 2: the preparation of NITI-2 and NITI-3

[0079]

[0080] The preparation process of NITI-2 and NITI-3 is basically the same as that of NITI-1, the only difference is that compound 2 is replaced by compound 5 or 6.

[0081] NITI-2 yield 93%. MS(MALDI-TOF):1754.2[M] + .

[0082] NITI-3 yield 88%. MS(MALDI-TOF):1754.2[M] + .

Embodiment 3

[0083] Embodiment 3: the preparation of NITI-4

[0084]

[0085] The preparation process of NITI-4 is basically the same as that of NITI-2, the only difference is that compound 1 is replaced by compound 7.

[0086] NITI-4 yield 95%. MS(MALDI-TOF):1562.1[M] + .

Abstract

The invention relates to the technical field of photovoltaic receptor materials, in particular to an indenoindene photovoltaic receptor material shown as a formula I, a method for preparing the indenoindene photovoltaic receptor material and application thereof. The indenoindene photovoltaic receptor material which is a compound, the method and the application possibly have the advantages that each indenoindene structural unit is provided with two SP<3> carbon bridges, the SP<3> carbon bridges can be connected with groups with high steric hindrance, and accordingly the indenoindene photovoltaic receptor material is favorable for phase separation of donors and receptors; indenoindene is provided with 14 pi electrons and large conjugate plane areas as compared with a fluorene structural unitof 12 pi electrons, and accordingly the indenoindene photovoltaic receptor material can be high in migration rate; the indenoindene photovoltaic receptor material which is an indenoindene small-molecule receptor material is excellent in photoelectric conversion efficiency.

Description

technical field [0001] The invention relates to the field of photovoltaic acceptor materials, in particular to an indenoindenyl photovoltaic acceptor material, a preparation method and application thereof. Background technique [0002] The development of energy is a common concern of the whole world and all mankind, and it is also an important issue of social and economic development. The main energy used by humans includes non-renewable resources such as coal, oil, and natural gas. After burning these energy sources, a large amount of carbon dioxide and other harmful gases will be produced, which will aggravate the greenhouse effect and air pollution. Reserves are fixed, so it is necessary to find alternative new energy sources. Solar energy, as an inexhaustible and pollution-free green energy, has received widespread attention. How to efficiently utilize solar energy has become a concern of people. Organic thin-film solar cells are the fastest growing and most attention...
