The role of counter-anions in the kinetics and chirality of porphyrin J-aggregates

Chem Commun (Camb). 2016 Sep 20;52(77):11520-11523. doi: 10.1039/c6cc05768c.

Abstract

Kinetics of the growth of TPPS4 porphyrin J-aggregates slow down in the order H2SO4 > HCl > HBr > HNO3 > HClO4, in agreement with the Hofmeister series. The rate constants and the extent of chirality correlate with the structure-making or breaking abilities of the different anions with respect to the hydrogen bonding network of the solvent.
