TL;DR: Takashima et al. as discussed by the authors showed that the association constants of trans-AzBA-AAm copolymers with -CD are larger than those of cis-Az-BA- AAm co-polymers.
Abstract: Yoshinori Takashima, Tomofumi Nakayama, Masahiko Miyauchi, Yoshinori Kawaguchi,Hiroyasu Yamaguchi, and Akira HaradaDepartment of Macromolecular Science, Graduate School of Science, Osaka University,Toyonaka, Osaka 560-0043(Received March 25, 2004; CL-040332)The copolymers of acrylamide and acrylamide with pendantazobenzene (AzBA–AAm) were prepared by radical polymer-ization. The association constants of trans-AzBA–AAm copoly-mers with -CD are larger than those of cis-AzBA–AAm co-polymers. The trans-AzBA–AAm guest copolymer was foundto form supramolecular gels with

TL;DR: A series of bis(dialkylamido) titanium complexes coordinated by O-E-O (E=S, CH 2 ) chelating bis(aryloxo) ligands were synthesized by the reaction of Ti(NR 2 ) 4 (R=Me, Et) with 2,2 ′ -E(4-Me-6- t BuC 6 H 2 OH) 2 (E =S,CH 2 ) as mentioned in this paper.

TL;DR: In this paper, polyisoprenes were found to form inclusion complexes with cyclodextrins with high selectivity to give crystalline compounds, and β-Cyclodextrin formed complexes only with polyisopsrene of low molecular weigth.
Abstract: Polyisoprenes were found to form inclusion complexes with cyclodextrins with high selectivity to give crystalline compounds. β-Cyclodextrin formed complexes only with polyisoprene of low molecular weigth, whereas γ-cyclodextrin formed complexes with polyisoprenes of high molecular weight. α-Cyclodextrin did not form complexes with polyisoprene of any molecular weight. The yields of γ-cyclodextrin complexes increased with increasing molecular weights of the polyisoprenes and reached a maximum of around several thousands, and then decreased.
