Life systems have evolved to utilize weak noncovalent interactions, particularly CH-π interaction, to achieve various biofunctions, for example cellular communication, immune response, and protein folding. However, for artificial materials, it remains a great challenge to recognize such weak interaction, further transform it into tunable macroscopic properties and realize special functions. Her...

A novel route to highly aromatic polyimides is presented and used form multiblock copolymers which inherently difficult achieve via traditional routes for this important polymer family.

Heteronuclear dipole-to-dipole cross-relaxation has been applied to exploring intermolecular interactions and intramolecular spatial proximities in a large supramolecular structure comprised of a beta-barrel membrane protein, OmpX, in complex with a polymeric surfactant, amphipol A8-35. The experiments, performed in either the laboratory or the rotating frame, reveal the existence of intermolec...

A microbial fermentation system was designed to convert glucose to 4-hydroxyphenyllactic acid (DHPA), which is an aromaticcontaining derivative of lactic acid. By methylation, DHPA was transformed to a diol monomer for synthesis of bio-based polyesters with benzene rings in their backbone. The polycondensation of the DHPA diol was performed with a series of aliphatic diacid chlorides to produce...

A novel quinoid–donor–acceptor strategy to design a quinoidal–aromatic conjugated polymer PAQM-BT is established. hole mobility of up 5.10 cm 2 V −1 s in OFETs realized, which among the highest values for polymers.

Laccases oxidize variety of aromatic and non aromatic compounds by using oxygen as the electron acceptor and producing water as by-product. Generally laccases need mediators for catalyzing the removal of lignin from pulp. The potential of laccase mediator system (LMS) to degrade lignin polymer has been demonstrated by many researchers, but still the high cost and possible toxicity of artificial...

The 6 H -[1,2,5]thiadiazolo[3,4- e ]thieno[3,2- b ]indole-flanked para -azaquinodimethane ( p -AQM)-based polymer semiconductors PQ-1 and PQ-2 are rationally designed through a ?-extended aromatic-quinoidal design strategy.
