Effects of π-extension on pyrrole hemithioindigo photoswitches

, (2019/08/08)
The most red-shifted hemithioindigo photoswitches have been identified through systematic introduction of aryl units to a parent pyrrole hemithioindigo photoswitch. Increasing the size of the 5′-aryl substituent is ineffective at producing further redshif

A modular synthesis of unsymmetrical BODIPY dyes based on a [6π] electrocyclization to construct both pyrrole rings is presented. The products carry four aryl moieties in positions 1, 3, 5, and 7, which can be freely selected, as well as optional substitution in positions 2 and 8. The method employs acetophenones, benzaldehydes as well as glycine nitrile or glycine ethyl ester as the key building blocks.
