[Abstract]:In recent years, more and more attention has been paid to the synthesis and application of heterocyclic polycyclic aromatic compounds. Their applications in organic semiconductor devices have attracted widespread interest, such as in the presence of airfield effect transistors. Organic photovoltaic cells and other applications in the field. Heterocyclic polycyclic aromatic compounds have the advantages of high mobility, high current switching ratio and good solubility. A series of heterocyclic phenanthrene compounds have been designed and synthesized in view of their good optoelectronic properties. The characteristic of these compounds is that all of them have a C _ 3-asymmetric structure, and all of them have C _ 3-asymmetric structure. A series of compounds synthesized with Benzo phenanthrene as parent nucleus all have relatively large conjugated systems. The first part of this paper is about the synthesis of C _ 3-asymmetric trifuran / trithiophene phenanthrene derivatives. The key precursor, 2O6, 11- trihalogen-3-trimethoxybenzofen, was prepared from o-bromophenyl ether or o-chlorophenyl ether with concentrated sulfuric acid as catalyst and ferric chloride as oxidant. Asymmetric benzophenanthrene 2o 6n 11- trihalogenated -3 haloanilo-10 trimethoxy benzophenanthrene was synthesized by trimerization, and the synthesis of C 3 asymmetric benzophenanthroline furan and its derivatives was carried out by means of 2 '611- tribromo-trimethoxybenzophenanthene (TMEB), which was used as raw material for the synthesis of C3- asymmetric benzofuran and its derivatives, and was used as the raw material for the synthesis of C3- asymmetric benzofuran. The demethylation of boron tribromoxide (BBS) was carried out to form 2n 6n 11- tribromo-3H 710-trihydroxy benzofen. Palladium catalyzed Sonogashira coupling reaction of acylated products from phenolic hydroxyl groups protected by acetic anhydride with a series of alkynes was carried out, and the products were obtained in the ring under the action of cesium carbonate. C _ 3- asymmetric benzophenothiophene and its derivatives were prepared by the demethylation of boron tribromoxide to form 2 ~ (611) -trichlorophenyl -7 ~ (10) -trihydroxy benzophenanthrene, and their derivatives were obtained by the demethylation of boron tribromoxide (B _ (3). After conversion from trifluoromethyl sulfonic anhydride to sulfonic acid ester, a series of alkynes were coupled with a series of alkynes through palladium catalyzed Sonogashira coupling reaction. Finally, the target product was obtained in the presence of sodium sulfide nine-hydrate. The second part of the thesis is the synthesis of a series of isotripolycarbazole / isotripolybenzofuran / isotripolydibenzothiophene derivatives from 2O6O6-TIBROMO-3BROMO-710TIMETHYXYBENZHENYL. (1) using 2O6O6-TIBROMO-3710- TIMETHYLBENE and o-TYDROXYBENE as raw materials. The intermediates with six methoxy groups were obtained by Suzuki coupling of methoxy phenylboric acid with the action of Pd132. Six phenolic hydroxyl compounds with biphenyl structure were obtained by demethylation with boron tribromide. The phenolic hydroxyl compounds reacted with trifluoromethyl sulfonic anhydride to obtain sulfonates and then reacted with a series of anilines to obtain isotripolycarbazole compounds. (2) using 2O6O6-tribromo-3-trimethoxybenzophenanthrene as raw material and o-chlorobenzene boron as the raw material, iso-tripolycarbazole compounds were obtained by the reaction of phenolic hydroxyl compounds with trifluoromethyl sulfonic anhydride. Acid was coupled by Suzuki under the action of catalyst Pd132. Then the methoxy group was removed under the action of boron tribromide, and finally the iso-tripolybenzofuran compound was obtained by closing the ring. In addition, the product was activated by C-H in the presence of cesium carbonate, and demethylated with tribrominated benzophenanthroline, which was used as a raw material for the removal of methyl protection group by tribromination, and the product was activated by C-H in the presence of cesium carbonate, and the product was activated by C-H in the presence of cesium carbonate. A tricyano-substituted isotripolydibenzofuran derivative was synthesized. (3) Suzuki coupling reaction took place with o-fluoroborate boric acid under the catalysis of Pd132. Then the tribromoboron demethylated to form 3o 7N 10 tris (2 fluorophenyl) -2N 611 trihydroxy benzophenanthrene, then sulfonated with trifluoromethyl sulfonic anhydride, and then the sulfonation product reacts with ethyl mercaptopropionate. Finally, isotrimeric dibenzothiophene was obtained by closing the ring of potassium tert-butanol.
