Aza-analogues of distyrylbenzene (DSB) synthesis, structures, and properties of 1,4-phenylenediamine bisimines (PDABI)
… increased bandwidth, modulation response ([pi] electron response), and decreased expense. We are focused on the creation of dipole parallel-aligned crystals as potential players for use as electro-optic materials. The successful synthesis of several near-perfect and perfect parallel dipole …

Development of Conjugated Boronate Ester-Linked Materials For Optical Sensing Applications Targeting Small Molecules
… electronic properties of these esters. Spectroscopic observations and computational studies of these compounds suggested that both the central aromatic components and substituents on the terminal diols can affect the electronic properties. The extension of pi-conjugation through the vacant p …

Synthesis, Linear and Nonlinear Photophysical Characterization of Two Symmetrical Pyrene-terminated Squaraine Derivatives in Solution
… stability in THF, and the linear spectroscopic characterization revealed high extinction coefficients, large fluorescence quantum yields and relatively low tendency of forming excimers in several solvents. The nonlinear spectroscopic study revealed two-photon absorption cross section maxima …
