For the first time bichromophore nonlinear optically active compounds, 3,5-bis [2- (N-ethyl-4- (4′-nitrophenylazo) anilino) ethoxy] benzyl alcohol, DF1, and 3,5-bis [6- (N-methyl-4- (4′-nitrophenylazo) anilino) hexaoxy] benzyl alcohol, DF2, have been synthesized. The synthesis of the epoxy-amine oligomers containing DF1 and DF2 dendritic fragments in the side chain was preceded by molecular design which demonstrated that the hexyl groups, binding the chromophores to the branching center in DF2, are able to provide greater mobility of the chromophores compared to the ethyl groups in DF1, thus determining the preference of the former from the viewpoint of NLO activity. Bi-chromophore compounds were introduced into the side chain of epoxy amine oligomers using the esterification reaction under mild conditions by the Steglich method. As a result, oligomers OAB-DF1 (Tg = 122 °C) and OAB-DF2 (Tg = 107 °C) were obtained with good yields, the degree of functionalization was 60 mol% and 45 mol%, respectively. The values of the NLO coefficients, d33, were measured by second harmonic generation technique; they are equal to 29 pm/V for OAB-DF1 and 40 pm/V for OAB-DF2.

New types of "X-type" NLO dendrimers, C2 and C3, in which the chromophore moieties were arranged in order, were rationally designed. The special topology of the chromophore moieties contributed a great deal to the good NLO performance of C2 and C3: the d33 value of C2 (containing only five chromophore moieties) was 157.4 pm V-1, while that of C3 (containing nine chromophore moieties) achieved 195.2 pm V-1, much larger than that of C1 (74.7 pm V-1, containing three chromophore moieties) and the fifth generation dendrimer (G5) (193.1 pm V-1, bearing 62 pieces of chromophore moieties). Through careful experimental and theoretical analysis, their structure-property relationship was explained, and discussed in detail.

-
Paragraph 0125; 0152, (2013/09/12)
Provided are compounds according to the following Formula I: The Formula I compounds are activated in the presence of reactive oxygen species (ROS) and are therefore selective anti-cancer therapeutics for cancers associated with elevated ROS. Also provided are methods and pharmaceutical compositions for treating cancers associated with increased ROS.
