The apparent dipole moments (μ) of 2-methoxyethanol (C1E1), 2-ethoxyethanol (C2E1), 2-(2-methoxyethoxy)ethanol (C1E2), and 2-(2-ethoxyethoxy)ethanol (C2E2) were determined in heptane solutions for the mole fraction range of 0 < x < 0.03 at T = 298.15 K. To calculate μ values the molar volumes for these solutions and the refractive indices of the pure components were determined at T = 298.15 K. FT-IR spectra for these solutions were also measured at T = 298 K. The conformations of these compounds and that of the dimer of C1E1 were predicted by ab initio calculations. In order to compare the calculated results with experimental, a statistical calculation was performed. The calculated conformers of the isolated molecules correlated well with the experimental results of the dipole moment and the IR spectra.

Highly sensitive photoinitiator takes an important role in the improvement of photo-polymerization for the advanced manufacturing of microsteric structures of the color filter. In the present work, we have investigated photosensitivity of a novel oxime ester photoinitiator with benzocarbazole as a chromophore in the polymerization process. By comparing the residual thickness of polymerized films in the color resists with those obtained by other oxime ester photoinitiators, it was found that the high absorption intensity at the i-line significantly increased the bottom-curing performance with good surface curing. Moreover, it was revealed that high quantum yield of this new photoinitiator also contributed to the increase in the high photosensitivity.

The relative permittivity (εr) and the conductivity (κ) at a frequency (f) of 50 kHz, and the dynamic light-scattering were measured for ternary systems of (AOT + r·H2O) solved in cyclohexane, heptane, octane, decane, and dodecane at a temperature of 298.15 K as a function of the amount ratio (r) of water to AOT (r = [H2O]/[AOT]) up to the onset of percolation. The molality (m) of AOT for those solutions was 0.15 mol kg−1, and increased to 0.30 mol kg−1 for solutions with dodecane. By increasing r, spherical reversed micelles were formed at r ≈ 6 in straight-chain hydrocarbons. The light-scattering measurements indicated that the mean hydrodynamic diameter of the micelles increased with increasing r, showing a sigmoid curve. The growth of micelles was promoted in a longer chain hydrocarbon. The percolation transition occurred as the particles grew to a critical diameter of about 50 nm. On the other hand, the growth of particles in c-hexane was moderate, and percolation did not occur up to r = 90, where the solution turned turbid. The growth of particles found from light-scattering measurements was well correlated to dielectric observations.
