Cool down and get it together! The lower critical solution temperature (LCST) behavior of a polymer containing pyrene units was controlled by a charge‐transfer (CT) interaction with an electron‐accepting effector (see picture). The appearance of CT bands enabled quantitative evaluation of the thermodynamics of the association.

Bispyridyl hydrogen bonding receptor 1 forms colored charge transfer (CT) complexes with complementary phenols and naphthols. Despite its low association constants of similar to 10(1) M(-1), receptor 1 was highly selective forming CT complexes of varying color and intensity with different diol guests. The selectivity of 1 was correlated with the ability of its CT band to simultaneously yield information about the association constant and the electronic structure of the phenols and naphthols.

including poly(dimethylsiloxane) and oligo(dimethylsiloxane), were used to evaluate aromaticdonor–acceptorinteractionsbetween pyrene and pyromellitic diimide derivatives. The donor–acceptorinteractions were stronger in siloxane solvents than in aliphatic solvents, possibly because of the poor solubility of the aromatics in siloxanes.
