Three molecular threads incorporating two viologen units attached by an oligo-ethylene glycol chain of variable length and an electron rich naphthalene moiety were prepared. The internal viologen unit is connected to the naphthalene by a rigid linker that
Rational adjustment of multicolor emissions by cucurbiturils-based host-guest chemistry and photochemistry

The host-guest chemistry of cucurbiturils and the photochemistry of azastilbene derivatives are combined for the rationally adjusting multicolor emissions through forming different host-guest complexes and their corresponding photochemical products. Cucurbit[8]uril (CB[8]) can bind with azastilbene derivatives to form supramolecular polymers emitting orange light. The supramolecular polymers further facilitate the [2 + 2] cycloaddition of C=C bonds in azastilbenes by UV irradiation, emitting blue light. Different from CB[8], cucurbit[7]uril (CB[7]) encapsulates azastilbene derivatives to form a dumbbell-shaped host-guest complex, emitting dark-purple light. This dumbbell-shaped host-guest complex undergoes cis-isomerization after UV irradiation, thus emitting green light. Therefore, this strategy is promising for fabricating advanced stimuli-responsive fluorescent materials.

Stereselectivity control in anomeric O-alkylation. Application to the synthesis of C2 symmetric glycoconjugates

Tetrbutylammonium salts strongly influence the stereoselectivity of O-anomeric alkylation and allows to shift from β to α selectivity. Allyl glucosaminide 7 prepared in this way, was used to synthesize die new type of C2 symmetric neoglycoconju
