Liquid-crystalline behaviour and electrorheological effect of phthalocyanine-based ionic liquid crystals

Poly(l-Lactide) Liquid Crystals with Tailor-Made Properties Toward a Specific Nematic Mesophase Texture

“…The analysis of the X-ray pattern of the pressed PLLA with thread-like texture at 25 °C (Figure , PLLA110) shows the presence of the reflections at wide angles confirming a crystalline fraction and an amorphous halo in the 2θ region 8°–26° on the flat film diffractogram, which arises from the interchain spacing and is responsible probably for N* mesophase existence . It is known that a nematic mesophase only shows a diffuse halo in a high-angle region. , The X-ray analysis confirmed the results of DSC and POM investigations and indicated that the obtained materials exhibited both crystalline and nematic behavior. However, detailed information about the molecular organization within the various phases at different temperatures can be obtained by X-ray diffraction measurements as a function of the temperature.…”

Nematic-to-Isotropic Phase Transition in Poly(L-Lactide) with Addition of Cyclodextrin during Abiotic Degradation Study

“…The analysis of the X-ray pattern of pressed PLLA/RM-β-CD at 25 °C ( Figure 6 ) shows the presence of the reflections at wide angles, confirming a crystalline fraction and an amorphous halo in the 2θ region of 5–27° on the flat film diffractogram, which arises from the interchain distances, and is probably responsible for the existence of the N* mesophase [ 46 ]. It is known that a nematic mesophase only shows a diffuse halo in a high-angle region [ 47 , 48 ]. The point here is that the LC regions can cover all or only a part of the material.…”

Synthesis, characterization, DNA interaction, molecular docking, and α-amylase and α-glucosidase inhibition studies of a water soluble Zn(ii) phthalocyanine

“…Phthalocyanine compounds are unique macrocyclic molecules with an 18 π electron system that are used in many areas such as catalysts, liquid crystals and organic semiconductors as well as therapeutic agents for anticancer, antibacterial and antiviral treatments. [1][2][3][4][5][6][7][8][9][10][11][12][13] The piperidine ring is a valuable saturated heterocyclic compound with various biological activities found in the structures of many natural alkaloids. [14][15][16][17][18] The DNA molecule is one of the primary targets for many drug molecules used in anticancer, antibacterial, antiviral and antimalarial treatments, due to its main cellular functions such as replication and transcription.…”
