摘要：

Comprehensive Summary Isoindigo (IID) is widely used as organic dye and conjugated unit in opto-electronic materials. Functionalization of IID to increase its structural complexity is demanding for obtaining diversity properties. Herein, we developed a direct C-H/N-H activation method of IIDs via double alkyne annulations and synthesized pi -extended IIDs with two pairs of 5/7 membered rings. The structure of the pi -extended IIDs was characterized and confirmed by H-1 NMR, C-13 NMR, HRMS and X ray crystal analysis. Their physical properties were characterized by UV-vis absorption, cyclic voltammetry and thermogravimetric analysis. The absorption coefficient of the annulated products enhanced significantly compared with the non-annulated analogue.
