Structural, photoelectrical and thermol properties of ultra-stable Benzo[ghi]perylene trimide dimer anion

Perylene diimide and its various derivatives tend to form stable anion radicals , which can usually form a variety of aggregates with special properties. Herein, we reported synthesis and properties of the benzo[ghi]perylene trimide and its anion radical π-bonded dimer. The dimer exhibited high stable in solid status and in most organic solvents , but conversion of L-type π-bonded dimer to face to face type π-bonded dimer or π-stacked oligomer occurs in dimethyl formamide solution. The temperature and crystallization influenced the π-bonded length in the dimer and the partial memory can be reserved and probed in solution at room temperature .
