The highly rigid and planar scaffolds with π-conjugated systems have been widely considered to be indispensable for β-amyloid (Aβ) binding ligands. In this study, a library of diphenoxy compounds with different types of more flexible linkers as Aβ ligands were synthesized and evaluated. Most of them displayed good affinity (Ki1-42aggregates, and some ligands even showed values of Kiless than 10 nM. Structure-activity relationship analysis revealed that modification on the linkers or substituents tolerated great flexibility, which challenged the long-held belief that rigid and planar structures are exclusively favored for Aβ binding. Three ligands were labeled by iodine-125, and they exhibited good properties in vitro and in vivo, which further supported that this flexible scaffold was potential and promising for the development of Aβ imaging agents.

, p. 19666 - 19674 (2015/05/12)
A series of azomethine functionalized diols were synthesized by the condensation reaction of aromatic diamines with 4-hydroxy benzaldehyde. Aromatic diamines with different alkyl chain lengths have been used to prepare the bisphenols. These bisphenols wer

, p. 92 - 98 (2015/05/20)
A series of some novel epoxy-amine polymers was successfully synthesized by using DGEBA and aromatic diamines as starting materials. The cured free standing flexible polymer films were characterized by FTIR, DSC, TGA, and WAXD. The values of Tg

scheme or table, p. 10935 - 10941 (2012/04/23)
The synthesis and characterisation of two new series of liquid crystal tetramers in which four mesogenic groups are linked via three alkyl spacers is reported. In each series the length of the outer two spacers, n, is varied between 3, 4, 5, 7, 10 and 11
Semiflexible liquid crystalline tetramers as models of structurally analogous copolymers
Henderson, Peter A.,Imrie, Corrie T.
, p. 3307 - 3311 (2007/10/03)
The synthesis and characterization of a series of liquid crystal tetramers is reported. These consist of molecules containing four liquid crystal units connected via three flexible alkyl spacers. The length of the central spacer is held at six methylene u
Main chain polymers containing banana-shaped mesogens: Synthesis and mesomorphic properties
Choi, E-Joon,Ahn, Jae-Chul,Chien, Liang-Chy,Lee, Chong-Kwang,Zin, Wang-Cheol,Kim, Dae-Cheol,Shin, Sung-Tae
, p. 71 - 78 (2007/10/03)
Twelve azomethine polymers containing a banana-shaped mesogen as a repeating unit have been synthesized by polycondensation, and their mesomorphic properties were studied. The solution viscosities were measured in a 0.16 g/dL solution in H2SOs
Liquid crystalline behaviour of polymer networks based on segmented chain mesogenic polymers
Aurino,Caruso,Pragliola,Roviello,Sirigu
, p. 99 - 109 (2007/10/03)
The synthesis of some crosslinked polymers based on a segmented-chain polymeric mesogen containing variable amounts of a side chain substituent is reported. The unswollen networks show thermotropic mesomorphism of nematic character whose stability decreases with increasing substitution and crosslink density. Depending on the same parameters, the swollen networks may show optical anisotropy at room temperature whose origin is attributed to phase separation.
