Structures of five fluorescence compounds available for
in vitro
imaging with two-photon absorption cross section greater than 500 GM and
one example of the superfluorescence properties of 2,2′-(5,5′-(9,9-didecyl-9H-fluorene-2,7-diyl)bis(ethyne-2,1-diyl)bis(thiophene-5,2-diyl))-dibenzo[d]-thia-
zole with their two-photon induced green emission
in vitro
[139-143].
