The syntheses and electrooptic properties of a new family of nonlinear optical chromophores are reported. These species feature an ethyne-elaborated, highly polarizable porphyrinic component and metal polypyridyl complexes that serve as integral donor and acceptor elements. Examples of this structural motif include ruthenium(II) [5-(4?-ethynyl-(2,2?;6?, 2?-terpyridinyl))-10,20-bis(2?,6?-bis(3, 3-dimethyl-1-butyloxy)phenyl)porphinato]zinc(II)- (2,2?;6?,2?-terpyridine)2+ bis-hexafluorophosphate (Ru-PZn); osmium(II) [5-(4?-ethynyl-(2,2?;6?, 2?-terpyridinyl))-10,20-bis(2?,6?-bis(3, 3-dimethyl-1-butyloxy)phenyl)porphinato]zinc(II)-(2, 2?;6?,2?-terpyridine)2+ bis-hexafluorophosphate (Os-PZn); ruthenium(II) [5-(4?-ethynyl-(2,2?;6?, 2?-terpyridinyl))-15-(4?-nitrophenyl)ethynyl-10, 20-bis(2?,6?-bis(3,3-dimethyl-1-butyloxy) phenyl)porphinato]zinc(II)-(2,2?;6?, 2?-terpyridine)2+ bis-hexafluorophosphate (Ru-PZn-A); osmium(II) [5-(4?-ethynyl- (2,2?;6?,2?-terpyridinyl))-15- (4?-nitrophenyl)ethynyl-10,20-bis(2?, 6?-bis(3,3-dimethyl-1-butyloxy)phenyl) porphinato]zinc(II)-(2,2?;6?,2?-terpyridine)2+ bis-hexafluorophosphate (Os-PZn-A); and ruthenium(II) [5-(4?-ethynyl- (2,2?;6?,2?-terpyridinyl))osmium(II) -15-(4?-ethynyl-(2,2?;6?,2?-terpyridinyl))-10,20-bis (2?,6?-bis(3,3-dimethyl-1-butyloxy)phenyl) porphinato]zinc(Il)-bis(2,2?;6?, 2?-terpyridine)4+ tetrakis-hexafluorophosphate (Ru-PZn-Os). The frequency dependence of the dynamic hyperpolarizability of these compounds was determined from hyperRayleigh light scattering (HRS) measurements carried out at fundamental incident irradiation wavelengths (lambdainc) of 800, 1064, and 1300 nm. These data show that (i) coupled oscillator photophysics and metal-mediated cross-coupling can be exploited to elaborate high beta0 supermolecules that exhibit significant excited-state electronic communication between their respective pigment building blocks; (ii) high-stability metal polypyridyl compounds constitute an attractive alternative to electron releasing dialkyl- and diarylamino groups, the most commonly used donor moieties in a wide range of established nonlinear optical dyes; (iii) this design strategy enables ready elaboration of chromophores having extraordinarily large dynamic hyperpolarizabilities (betalambda values) at telecommunication relevant wavelengths; and (iv) porphyrin B- and Q-state-derived static hyperpolarizabilities (beta0 values) can be designed to have the same or opposite sign in these species, thus providing a new means to regulate the magnitude of lambdainc-specific dynamic hyperpolarizabilities.
Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. Synthetic Route of 128143-88-4, If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 128143-88-4, in my other articles.
