The novel 1,16:6,7:8,9:14,15-tetranaphthoterrylene tetracarboxdiimide was synthesized via a straightforward route, yielding optically active atropisomers with a high racemization barrier. Absorption, fluorescence, and circular dichroism measurements revealed high absorption coefficients and fluorescence quantum yields and enabled the stereochemical assignment in combination with quantum mechanical calculations.

Two novel core-extended terrylene diimides on the bay region (CETDIs) were synthesized via annulation of the four additional ethylene units or benzene units on the bay region of the terrylene diimide core. The optical and electrochemical properties of the two compounds were investigated. These CETDIs exhibited broad absorption spectra with high extinction coefficients, which span a wide range in the ultraviolet and visible spectrum from 300 to 700 nm.
