Optical properties of π-conjugated donor-acceptor systems with controlled hyperpolarizability
For supramolecular compounds with donor and acceptor fragments, coupled with each other by the π-conjugated methyn chain, it was ascertained an influence of Cl and Br atoms on the π-conjugation and charge transfer in them in molecular and aggregate states. Compound, which contains Br atom, crysta...

| description |
For supramolecular compounds with donor and acceptor fragments, coupled
with each other by the π-conjugated methyn chain, it was ascertained an influence of
Cl and Br atoms on the π-conjugation and charge transfer in them in molecular and
aggregate states. Compound, which contains Br atom, crystallizes into a noncentrosymmetric
polar structure and under infrared (1064 nm) laser excitation it is observed the
second harmonic generation and intense up-conversion photoluminescence in the visible
spectral region. For compounds containing Cl atom, when passing into a crystalline state,
only up-conversion photoluminescence is observed, which can be considered as twophoton
excited. Possible mechanisms of intramolecular charge transfer and collective
interactions in investigated molecular structures under one- and two-photon excitation
are considered. |
