Two different donor subunits substituted unsymmetrical squaraines exhibited a totally different aggregation.

The USQ-11/PC71BM blend film displayed quite smaller domains size than that of the USQ-12/PC71BM.

The PCE of USQ-11-based solution-processed BHJ-SMOSCs was much higher than that of USQ-12 (4.27% vs. 2.78%).

2,3,3-Trimethylindolenine unit should be an excellent D subunit for construction of squaraines photovoltaic materials.
