Pillar [n] arenes are a novel class of macrocyclic hosts reported by Ogoshi and co-workers in
2008. Because of their rigid pillar structures, interesting host–guest properties and ease of …

Pillar [n] arenes primarily comprise pillar [5] arenes and pillar [6] arenes, which belong to the
new class of supramolecular macrocyclic hosts. Pillar [n] arenes have aroused wide …

Studies on various macrocyclic arenes have received increasing attention due to their
straightforward syntheses, convenient derivatization, and unique complexation properties …

Achieving room temperature phosphorescence (RTP) of heavy-atom-free organic molecules
with near-infrared (NIR) emission in solutions is fascinating for medical and biological …

The low quantum efficiency in the solid phase and the highly efficient quenching by oxygen
are two major weaknesses limiting the practical applications of triplet–triplet annihilation …

Spatial arrangement of multiple planar chromophores is an emerging strategy for molecule-
based chiroptical materials via easy and systematic synthesis. We attached five pyrene …

Abstract Pillar [5] arene-based molecular universal joints (MUJs), bearing fused crown ether
subring (MUJ1 and MUJ3) or a ring without ether oxygen atom (MUJ2), were synthesized …

A novel type of host–guest recognition systems have been developed on the basis of a Au
(III) molecular tweezer receptor and chiral Pt (II) guests. The complementary host–guest …

Triplet–triplet annihilation upconversion that converts low-energy photons to high-energy
photons with an incoherent exciting light source is attracting considerable attention due to …

The complexation of prism [5] arenes with amino acid derivatives showed association
constants of up to 107 M− 1, significant CD with gabs of up to 0.8× 10− 2 and CPL with glum …
