of the resulting thioketones with MeI and BF3·Et2O/TEA yielded a wide range of products in a simple manner, with selective alkylation of each pyrrole of the indacene core and with controlled functionalization at the meso position. A comprehensive combined photophysical and computational study has been conducted to determine the impact of the alkylation pattern, as well as the role of the conformational
