Nanoscale propeller-shaped conjugated mols. based on a central triphenylbenzene core bearing three oligomeric phenylene-vinylene branches having either electron-donating or electron-withdrawing peripheral groups were synthesized. These octupolar derivatives show definite solvatochromic behavior (in absorption and even more in emission), which reveals a multidimensional intramol. charge transfer (MDICT) taking place between the center and the periphery of the mols. Correlations between the solvatochromism magnitude and the nonlinear responses (1st-order hyperpolarizabilities β) of such derivatives were established. Accordingly, boosting of the MDICT phenomenon (by elongation of the branches and benefit from appropriate peripheral groups) allowed achievement of very high hyperpolarizabilities while maintaining wide transparency in the visible region (up to ||β|| = 810 × 10-30 esu for λmax = 377 nm).
Chemistry of Materials published new progress about Intramolecular electron transfer. 112-63-0 belongs to class esters-buliding-blocks, and the molecular formula is C19H34O2, Product Details of C19H34O2.
