Pandey, Ashwini,Singh, Bachcha
, p. 166 - 176 (2012)
A new series of liquid crystals involving cholesterol based mesogenic units and Schiff base moiety interlinked through ester linkage were designed and synthesized. The target compounds were obtained by the reaction of 4-(3-cholesteryl oxy carbonyl)benzald

Thisayukta, Jirakorn,Kamee, Hiroyuki,Kawauchi, Susumu,Watanabe, Junji
, p. 63 - 75 (2000)
We have synthesized a new banana-shaped compound, having naphthalene as a center of molecule. This compound exhibited an unconventional smectic texture by optical microscopy where the growth of small-fractal domains was observed. Moreover, two different chiral domains were found to form in the smectic phase as well as in the Smblue phase which can be considered to possess a helical structure. The details will be discussed.

A Bodipy (4,4-difluoro-4-bora-3a,4a-diaza-s-indacene) derivative has been conceived and synthesized starting from L-aspartic acid, as a selective turn-off sensor of Cu2?+ ions. Its acid–base properties were determined to study the formation of
Scale-up of the synthesis of a pyrimidine derivative directly on solid support
Meisenbach, Mark,Allmendinger, Thomas,Mak, Ching-Pong
, p. 553 - 558 (2003)
The solid-phase synthesis of 4-(2-amino-6-phenylpyrimidin-4-yl)benzamide, a compound obtained through combinatorial chemistry and parallel synthesis, can be scaled up directly on solid support in excellent yields and high purity. By applying highly loaded aminomethyl polystyrene as solid support, a good ratio between the product and the starting resin is achieved. For comparison, the synthesis was also performed in solution. The solid-phase synthesis approach has the advantage that the desired compound is easily and quickly accessible in sufficient quantities for early development demands.

Three novel boron-dipyrromethene (BODIPY) dyes bearing borneol moieties have been designed, synthesized and characterized. The single-crystal structure of the compound 3 was also elucidated for the first time. Their photophysical properties and confocal f
Distinct formation of a chiral smectic phase in achiral banana-shaped molecules with a central core based on a 2,7-dihydroxynaphthalene unit
Thisayukta, Jirakorn,Nakayama, Yusuke,Kawauchi, Susumu,Takezoe, Hideo,Watanabe, Junji
, p. 7441 - 7448 (2000)
We have prepared a novel series of banana-shaped molecules with a central bent core based on a 2,7-dihydroxynaphthalene group, the side wings containing a Schiff's based moiety, and alkoxy flexible tails with carbon numbers n = 6, 8, 10, 12, 14, and 16. Among these, the molecules with n = 8-16 formed a novel smectic phase. Its smectic layer possessed a liquidlike association of the molecules similar to the SmA or SmC phase, although the texture that developed from the isotropic melt was unconventional. Small fractal domains initially grew and then coalesced into several large domains. Very weak birefringence and fine structure without any anisotropy are characteristic of this phase. It is interesting to note that two different domains exist showing the opposite sign of optical rotation. Strong circular dichroism (CD) with a peak at 430 nm was also observed for each domain with the opposite sign. The results suggest a natural occurrence of the helix in these materials. The right-handed and left-handed helices were formed with equal probabilities, but the left-handed helix was selectively formed by the introduction of a chiral dopant. The molecule with n = 6 formed a frustrated smectic phase, which exhibited a simple fan-shaped texture.
