Abstract
Two new organic electron-donors derived from carbazole and phenothiazine, 9-Octyl-6-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl) carbazole-3-carbaldehyde and 10-octyl-7-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenoxazine-3-carbaldehyde, have been synthesized successfully. The process was initiated with multistep reactions, alkylation, formylation, bromination and finally borylation, to give the final products. The successful formation of each structure was confirmed by IR, H-1 NMR, C-13 NMR, and HRMS. The newly synthesized key electron donors could have promising roles as key intermediates in different synthetic approaches.
