TL;DR: Analysis of the cation-binding properties of the macrocycles by (1)H NMR and UV-vis spectroscopy reveals the formation of a 1:1 complex with Ba(2+), Sr(2-), or Pb(2+) and shows that cation complexation results in a conformational transition in the pi-conjugated system.

TL;DR: Reactions of chemically generated C60(2-) dianion with halo derivatives bearing a second functional group (halo, ester, ketone) give rise to new organo C60 derivatives, leading to new C60-based dyads as exemplified by two examples.

TL;DR: In this paper, a 1,2-and 1,4-dialkyl C60 adducts were characterized by 13C NMR studies including proton-carbon correlations.

TL;DR: The target compounds have been synthesized according to the method of Prato et al. as mentioned in this paper, and preliminary investigations of their electrochemical and optical properties have been conducted with respect to the small highest occupied molecular orbital-lowest unoccupiedmolecular orbital (HOMO-LUMO) gap of nTV.

TL;DR: A photodynamic molecular architecture synthesized by covalent fixation of a photoisomerizable azobenzene group at two fixed points of a conformationally flexible pi-conjugated quaterthiophene chain is synthesized, providing a first example of photomechanical control of the electronic properties of the pi- Conjugated system.
