Design, synthesis, and aggregation behavior of sandwich mixed (phthalocyaninato)(porphyrinato) europium triple-deckers: Effect of substituent on tuning the intermolecular interaction

Two novel sandwich triple-deckers were synthesized, and fabricated into self-assembled aggregates by using a solution-based method. Comparative investigation results reveal that the substituent groups play a critical role on tuning the intermolecular stacking, and in turn impact on electrical conductivity of materials.
