Embodiment 1

[0041] Embodiment 1: the synthesis of the sandwich type complex of tetrabenzoporphyrin-gadolinium (III):

[0042] In a 100ml three-necked flask, add 0.032mmol (20mg) of fused bicyclo[2.2.2]octadiene porphyrin and 0.09mmol (46.68mg) of gadolinium acetylacetonate (Gd(acac) 3 .nH 2 (0), under the protection of argon, the reaction bottle was placed in a heating device and protected from light. Quickly add 10ml of dried 1,2,4-trichlorobenzene. The system was heated to 220° C. rapidly, and the reaction was continued for 20 hours. The main product was a double-layer sandwich complex of tetrabenzoporphyrin-gadolinium (III).

[0043] Yield 42%; mass spectrum C 72 h 40 GdN 8 Calculated value: 1174.26, experimental value: 1174.26 ( Image 6 ); UV-Vis absorption spectrum: 400nm, 567nm, 765nm, 1344nm ( Figure 4 ).

Embodiment 2

[0044] Embodiment 2: the synthesis of the sandwich type complex of tetrabenzoporphyrin-gadolinium (III):

[0045] The method is the same as in Example 1, except that the reaction is prolonged for 48 hours, and the main product is a three-layer sandwich complex of tetrabenzoporphyrin-gadolinium (III).

[0046] Yield 37%; mass spectrum C 108 h 60 Gd 2 N 12 Calculated value: 1840.35, experimental value: 1840.36 ( Figure 7 ); UV-Vis absorption spectrum: 404nm, 573nm, 659nm ( Figure 5 ).

Embodiment 3

[0047] Embodiment 3: the synthesis of the sandwich type complex of tetrabenzoporphyrin-gadolinium (III):

[0048] The method is the same as in Example 1, except that the amount of the reaction solvent 1,2,4-trichlorobenzene is changed to 15 ml, and the yield is 41%.

Abstract

The invention discloses a preparation method and an application for sandwich type coordination compounds made from condensed bicyclo[2.2.2]octo diene porphyrin and rare earth metal gadolinium, which serve as light-absorbing materials at a visible light band in photoelectric functional material. The obvious red shift of the Soret spectral band and Q spectral band of the compounds relative to an octa-ethyl porphyrin-gadolinium coordination compound shows that the further extension of a pi conjugated system in a porphyrin ring causes the reduction of an HOMO-LUMO energy gap. Thus, the compounds 1 and 2 can have greater use to serve as light-absorbing materials at a visible light band in photoelectric functional material.

Description

1. Technical field [0001] The present invention relates to a synthesis method of a sandwich-type metal porphyrin complex and its application in solar cells, in particular to a sandwich-type sandwich complex of fused bicyclo[2.2.2]octadiene porphyrin and rare earth metal gadolinium . 2. Background technology [0002] Porphyrin compounds have good light and thermal stability, and the absorption spectrum is in the visible light range. They have many unique physical and chemical properties and other functional properties. field has been widely concerned and applied. In recent years, the use of porphyrin's unique electronic structure and photoelectric properties, the design and synthesis of photoelectric functional materials and the development of photoelectric devices have become very active research fields at home and abroad, and many important progresses have been made. In recent years, sandwich-type metalloporphyrin complexes with three-dimensional conjugated electronic str...
