Abstract

A series of molecular engineered organic glasses were synthesized based on the reversible self-assembly of aromatic/perfluoroaromatic Ar-[Ar.sup.F] dendron-substituted nonlinear optical (NLO) chromophores. These compounds improve poling efficiency and with their binary chormophore composites, they show enhanced electro-optic activities.

Abstract

The article introduces two-photon absorbing block copolymer that include energy transfer and singlet oxygen generation that serves as a nanocarrier for porphyrin. Using block copolymer as a nanocarrier encapsulates a hydrophobic porphyrin photosensitizer inside its aqueous solution. It proves that the efficient energy transfer contributes to an effective generation of singlet oxygen.
