, p. 147 - 150 (2018)
A tetraphenylethene (TPE) functionalized cationic pillar[5]arene (CWP5-TPE) was successfully synthesized, and the intramolecular rotation of the TPE motif was restricted via cationic pillar[5]arene-based host–guest recognition-mediated supramolecular self

New PPV derivatives containing cross-linkable acetylene groups, poly(2-methoxy-5-propagyloxy-l,4-phenylenevinylene) (PMPPV) and its PPV copolymers were synthesized through the soluble precursor polymers. PMPPV film was higly cross-linked and lost its properties of a conjugated polymer at over 200 °C. The electrical conductivities of PMPPV films were measured by four probe method after FeCl3 doping. The undrawn and 10 times drawn PMPPV films showed thier electrical conductivities of 1.5 × 10-1 and 92 S/cm, respectively. Conjugation length of poly(PV-co-MPPV) was controlled by changing the PMPPV monomer feed ratio.

As complex organisms vary in vivo, it remains a challenging task to get fluorescence 'turn on' imaging for special targets. To address this task, we have adopted a new strategy of inducing pillararene based host-guest interactions onto biocompatible graphene. By means of fluorescence competition displacement, hydrazino-pillar[5]arene modified graphene has been synthesized and provided as a 'turn on' probe for paraquat through monitoring of the fluorescence signal both in living cells and mice.
Acid/Base-Controllable FRET and Self-Assembling Systems Fabricated by Rhodamine B Functionalized Pillar[5]arene-Based Host-Guest Recognition Motifs

A series of 1,2,3-triazole-containing Sorafenib analogues, in which the aryl urea moiety of Sorafenib (1) was replaced with a 1,2,3-triazole ring linking a substituted phenoxy fragment, were prepared successfully via Huisgen 1,3-dipolar cycloaddition and
Enantioselective Palladium-Catalyzed Hydrophosphinylation of Allenes with Phosphine Oxides: Access to Chiral Allylic Phosphine Oxides

supporting information, p. 27288 - 27292 (2021/11/17)
A Pd-catalyzed hydrophosphinylation of alkyl and aryl-oxyallenes with phosphine oxides has been developed for the efficient and rapid construction of a family of chiral allylic phosphine oxides with a diverse range of functional groups. This methodology was further applied in the facile construction of chiral 2H-chromene and later stage functionalization of cholesterol.
Synthesis of pterocarpans through palladium-catalyzed oxyarylation of alkoxy-2H-chromenes with o-iodophenols

The oxyarylation of alkoxy-2H-chromenes (1a-e) with o-iodophenols substituted by electron-withdrawing (CHO) and electron-donating (OMe) groups is studied under two experimental conditions: a) Pd(OAc)2, Ag2CO3 in PEG-400 at 140 °C, 10 min and b) oxime-based palladacycle, DIPEA, in PEG-400 at 150 °C, 3–4 h. Pterocarpans are obtained in moderate to good chemical yields.
