“…It is of interest that related studies involving julolidine-stilbazolium salts were found to result in moderate χ (2) values. 11 The julolidyl functionality was expected to result in more efficient π-donation by allowing more efficient overlap with the aromatic ring and by virtue of the ortho-substitution, which had been shown to result in increased values of χ (2) in related derivatives (p-nitroaniline; β ) 35 × 10 -30 esu vs MNA (2-methyl-4-nitroaniline); β ) 42 × 10 -30 esu). In this case, incorporation of the julolidyl functionality had a pronounced effect resulting in χ (2) values that were less than that of the standard, urea.…”

A series of neutral pyridyl adducts involving the strong Lewis acids BF 3 and B(C 6 F 5 ) 3 has been prepared, and their second-order nonlinear optical coefficients (EFISH method) have been examined. The formation of the pyridyl-boron bond leads to enhancement of the dipole moments and second-order NLO coefficients (β and β(0)). Reactions of DMAP (4-Me 2 N-C 5 H 4 N) with BH 3 , BF 3 , and B(C 6 F 5 ) 3 give the corresponding neutral pyridine adducts DMAP‚-BH 3 (orthorhombic, Pbca, a ) 9.6914(7) Å; b ) 11.7173(9) Å; c ) 22.718(2) Å; V ) 1622.4(5) Å 3 ; Z ) 8; p ) 1.114 g cm -3 ), DMAP‚BF 3 (orthorhombic, Pbca, a ) 10.430(3) Å; b ) 8.111(2) Å; c ) 20.295(7) Å; V ) 1717.0(9) Å 3 ; Z ) 8; p ) 1.470 g cm -3 ), and DMAP‚B(C 6 F 5 ) 3 (orthorhombic, Pbca, a ) 12.322(1) Å; b ) 20.556(2) Å; c ) 28.455(3) Å; V ) 7207.4(14) Å 3 ; Z ) 8; p ) 1.508 g cm -3 ).

“…Before discussing the SHG efficiency of MPMS + I - , it is interesting to compare the second-order NLO properties of the new MPMS + chromophore versus those of the well-known DAMS + -related molecule. ,,, The UV−visible spectra of MPMS + I - and DAMS + I - recorded in ethanol are compared in Figure . It can be easily observed that both chromophores exhibit a similar intense, low-lying transition located at 484 nm (ε = 46200 mol -1 cm -1 ) and 481 nm (ε = 40 800 mol -1 cm -1 ) for MPMS + I - and DAMS + I - , respectively.…”

A new chiral cyanine dye, 4′-[2-(methoxymethyl)pyrrolidinyl]-1-methylstilbazolium iodide (MPMS + I -) is reported. It crystallizes in the monoclinic P2 1 space group. a ) 16.559(2) Å, b ) 6.263(1) Å, c ) 24.477(3) Å, β ) 109.20(1)°, Z ) 2. The hyperpolarizability of MPMS + Iis compared versus that of 4′-dimethylamino-1-methylstilbazolium iodide (DAMS + I -). MPMS + Iis phase matchable and exhibits an efficiency up to 80 times that of urea in second-harmonic generation (SHG). Both compounds (C + I -) react with tetracyanoquinodimethane (TCNQ), and the resulting C + (TCNQ 2 )exhibit conductivities in the range 10 -3 -10 -2 S cm -1 . The possibility of combining conductivity and optical nonlinearities is discussed.

Macroscopic non‐linearities of some stilbazolium derivatives and the calculatium derivatives and the calculation of their molecular hyperpolarisability

Abstract: The synthesis of some optically non-linear stilbazolium salts is described. Since their solid state non-linearities were small, MOPAC5 was used to compare their relative molecular non-linearities.
