Antiparallel interaction among dipolar chromophores is the dominant force in the solid state of conventional EO chromophores (long and flat). This interaction is responsible for the formation of acentric aggregates and prevents electro-optic coefficient from scaling with chromophore concentration. Antiparallel interaction can be selectively attenuated by attaching bulky groups to the middle part of chromophore. However, it is synthetically challenging to provide sufficient steric protection without causing severe reduction of chromophore concentration. In this paper, we will present the synthesis and characterization of atom-economic ring protection of chromophores against H-aggregation and show the effect of ring protection on optical properties of the chromophores in solution and film.
