Visible and near-infrared photoluminescence of a supramolecular complex constructed from a cycloparaphenylene nanoring and an erbium metallofullerene

Abstract

Erbium metallofullerenes exhibit near-infrared photoluminescence from the Er3+ ion, which has potential application in telecommunication, optical devices and bioscience. In this manuscript, we construct a supramolecular complex of metallofullerene Er3N@C80...

Two Rings Around One Ball: Stability and Charge Localization of [1 : 1] and [2 : 1] Complex Ions of [10]CPP and C60/70[*]

“…As hosts for numerous guest molecules such as smaller rings, [35][36][37][38] fullerenes, [38][39][40][41][42][43] fullerene dumbbells, [24,[44][45][46][47] endohedral metallo fullerenes, [36,[48][49][50][51][52] larger PAHs [53][54][55] and organic cations, [56] CPPs represent a tremendously important contribution to the world of noncovalent inclusion complexes. Bonding results from concave/convex π-π, CH-π and/or charge-π interactions between host and guest.…”

Metallofullertube: From Tubular Endohedral Structures to Properties

“…[34] Besides, a special supramolecular complex with both visible and near-infrared photoluminescence was also constructed by inserting the Er 3 N@C 80 into the cavity of [12]CPP. [35] Shortly before, an extensive overview of supramolecular purification and regioselective functionalization of fullerenes and metallofullerenes based on diverse host molecules has been published by Xavi Ribas's group. [36] For metallofullerene-based supramolecular complexes, the orientation of metallofullerene guest is interesting.…”

“…Recently, we also found that in DyY 2 N@C 80 ⊂[12]CPP the host‐guest interactions can influence the photoluminescence of fullerene cage [34] . Besides, a special supramolecular complex with both visible and near‐infrared photoluminescence was also constructed by inserting the Er 3 N@C 80 into the cavity of [12]CPP [35] .

A molecular Popeye: Li+@C60 and its complexes with [n]cycloparaphenylenes

“…Cycloparaphenylenes (CPPs) also represent very suitable host molecules for fullerenes and fullerene derivatives. Since their first synthesis by Jasti et al in 2008, 18 host-guest complexes between CPPs and pristine [19][20][21][22][23][24] and endohedral metallofullerenes [25][26][27][28][29][30][31] have been extensively studied. In 2015, Itami et al reported the first preparation and characterization of a complex between [10]CPP and Li + @C 60 .…”
