Abstract

Dichroic optical spectroscopies and theoretical modelling have been used to describe the structure of aggregates of porphyrins in their gels in terms of: (i) the formation of helicoidal structures, (ii) the sign of the handedness, (iii) their extent and degree of structural order, and (iv) the annealing of the structural defects.
