Abstract

AbstractThe synthesis of unsymmetrically peri-annulated naphthalene dyes, perimidinium imides (PrIm), is reported. Compared with the symmetrical and popular analogous naphthalenediimide dyes, PrIm showed a red-shifted absorption maximum. The water-soluble dyes showed tunable self-assembly behaviors and optical properties. The dyes retain their photoluminescence properties in water.
