Supramolecular aggregates constructed by pillar[5]arene-based host–guest interaction with aggregation-induced emission

Abstract

Herein, a novel pillar[5]arene-bridged monomer and the two sides functionalized with tetraphenylethylene (TPE) and nitrile group was designed and synthesized, which could form supramolecular aggregates based on the host-guest interaction...

A luminescent supramolecular polymer based on a stiff-stilbene bridged pillar[5]arene as a Pd2+-responsive smart material

“…On the other hand, series of P[5]-based AIE systems combined with tetraphenylethylene (TPE) have been reported for the fabrication of various functional materials. 38 This prompted us to develop stiff stilbene bridged P[5] dimers with TPE for applications hinging on SAIE. The current paper describes three things.…”

Active-metal template clipping synthesis of novel [2]rotaxanes

“…Since its birth, in the late sixties [1-3], the field of mechanically interlocked molecules (MIMs), including rotaxanes, has gained significant attention culminating by recognition with a Nobel prize in Chemistry in 2016. While initially obtained as chemical curiosities, rotaxanes offer now exciting opportunities for scientific advancements in supramolecular chemistry and applications in various fields ranging from molecular machines and switches [4][5][6][7][8][9] to catalysis [10,11], molecular electronics [12], and drug delivery [13]. In spite of the important advancements in this field, the synthesis and characterization of these fascinating, complex molecules remains an important challenge and often requires intricate synthetic approaches.…”

Fluorescence-enhanced supra-amphiphiles based on pillar[5]arene: construction, controllable self-assembly and application in cell imaging

“…[11][12][13][14][15] As the newest classical macrocycle for host-guest interactions, pillar [5]arenes were initially designed and synthesized in 2008 by the Ogoshi group. 16 Composed of five hydroquinone units connected by methylene at the para-position, pillar [5]arenes have pillar-like structures [17][18][19][20][21] The symmetrical structures and easy functionalization endow pillar [5]arene with good properties in host-guest chemistry. [22][23][24][25][26][27] Owing to the significant efforts of scientists, numerous stimuli-responsive host-guest recognition motifs of pillar [5]arenes have been constructed and further utilized in the production of various materials, including pillar [5]arene-based supramolecular polymers and supramolecular amphiphiles.…”
