Abstract

A new chiral and multichromophoric macromolecular system based on a perylene diimide chromophore
consisting of two 1,4-bis(3-aminopropyl) piperazine linkers and two terminal chiral naphthalene
bisimide chromophores has been synthesized. All of the chromophoric units are not p-conjugated with
each other and could behave independently due to the presence of the nonconjugated linker. A new
symmetrical dehydroabietyl substituted naphthalene diimide was also synthesized for comparison
purposes. The bulky and chiral substituent is included at the peripheral positions of macromolecular
system to increase the solubility and introduce directionality to the intermolecular interactions. The
multichromophoric macromolecule showed new and distinctive photophysical properties that are
different from the properties in the monomeric states of the components and in blends. It exhibited
strong absorption in a wide range (320–600 nm) with enhanced light absorption due to higher molar
absorption coefficients. It is observed that the absorption, emission and electrochemical characteristics
are delicate interplay among intermolecular interactions in the macromolecule both in solutions and
solid-state. Photoinduced electronic excitation energy transfer was noticed in various solvents from
energy-harvested peripheral chromophores to the centered perylene core.
